MityDSP Software Release Notes

1. All Windows software transitioned to VS 2010 and Qt version 4.8.2 to support automated building. MDK versions advanced, but no significant changes beyond those listed here.

1. Advanced version number for consistency.

1. On MityDSP-PRO, force PHY link lights on National Part to be link+activity.

1. Fixed a bug in tcDspI2C2 base class driver for I2C core version 2.0. The tcDspI2C2::read() failed to return a gnI2C_NO_ACK when a device failed to ACK the read request.
2. Added a tcDspAwgDual class (based off of tcDspAwg), for controlling a dual Arbitrary Waveform Generator FPGA core.
3. Added RECONFIG_CLOCKS macro in dsp_macros.h to support the MityDSP_Pro. It supports the following frequencies: CPU_FREQ_600MHZ, CPU_FREQ_800MHZ, CPU_FREQ_1000MHZ, and CPU_FREQ_1200MHZ.

1. Added support for tcp_sendflash command to upload complete FLASH image to a remote server via a simple TCP/IP protocol.
2. Added support for xmodem_sendflash command to upload complete FLASH image to a PC connected via serial port connection.

1. Add support for tcp_sendflash to extract FLASH image from connected MityDSP.
2. Fixed up state machine logic for flash image upload to properly close dialogs.

1. Fixed a bug in tcDspI2C2 base class driver for I2C core version 2.0. A TSK_lock handle was being used before it was initialized, resulting in unpredictible behavior.

1. Added tcDspI2C2 base class driver for I2C core version 2.0. Left tcDspI2C intact to support legacy I2C version 1.x cores fielded.

1. Fix a bug that occurred when a HSUSB port connection is made and the UART interfaces show no activity (e.g., are quiet / pulled down). Bugzilla #2020

1. Added the NIC IP address to the selection combo Bugzilla #2008.

1. Fixed a bug in the tcDspRomFs::open function where errors were returning error codes instead of just -1. This caused file descriptors to get used up after fopen returned with an error, eventually making it impossible to open any new files. Error codes are indicating by setting errno instead. Bugzilla #2006.
2. Fixed a bug in tcDspRomFs::lseek that caused any seek on a file, including an attempt to "rewind" the file to the beginning, to just seek all the way to the end of the file. Bugzilla #2006.
3. Updated DspMacros.h to change the internal PLLM output from 600 MHz to 400 MHz in the RECONFIG_CLOCKS macro. This alters the available CPU frequencies that may be used by the DSP (most importantly, 150 MHz is not an option anymore). This change is necessary due to a recent lot of MityDSPs that no longer function reliably with 600 MHz PLLM outputs. It appears to be a silicon issue at TI, but has not been confirmed. Applications using this macro should be rebuilt and redeployed using the DspMacros.h file in this release.
4. Updated constructor for DspCameraLink to handle cases where code is reloaded or initialized but the FPGA Camera Link core is active. Bugzilla #2002.

1. Fix but where GGUI was computing invalid region of text, leading to failure to update the display region that may have changed. Bugzilla #2005.

1. Added the ability to launch the MityGUI with a command line argument containing an ini file. (ex: MityGUI.exe –i “C:\Program Files\Alstom\TestFixtureGui\bin\MityTF.ini”)
2. New ini parm: mbHideGUI – will hide the gui from the user so that it can be run from another program
3. New ini parm: mRestartTimeoutmS – timeout value in which the gui will close if a target is never connected
4. New ini parm: mnStatusX, mnStatusY – if the gui is hidden then the status messages are displayed in a dialog box, so the calling program has feedback
5. Added the ability to run the batch command to only download the app file and the fpga file
6. Added an error code to be returned by the MityGUI when it closes
7. (4.0.3) Fixed bug in ethernet interface seleciton causing app to always use first listed interface.
8. (4.0.3) First time log is displayed, position it next to main window
9. (4.0.3) Fix tab order in ethernet options dialog

2. The bootstrapper now writes it's version number and version date information to the first two words of the base module scratch RAM after loading an application and prior to launching it. This will allow retrieval of the bootstrapper version number from the bootloader and the main application. Also copies the remainder of the scratchpad memory from old loaded to newly loaded fpga. Bugzilla #1179

1. Add trailing newline to Waiting for HEX file status text to support the high speed USB interface. Bugzilla #1732
2. Add preliminary support for the high speed USB core into the bootloader. Bugzilla #1553
3. Add optional TimeOut field for ipsetup DHCP command. Clear IP settings prior to running a DHCP request (via ipsetup dhcp command) in order to avoid nominal timeout issues with pickier routers. Bugzilla #1697
4. Add support for catching compressed DSP images and writing them to FLASH without byte swapping the data. This is an alternative to byte swapping the gzipped image prior to converting to an intel hex file.
5. Initialize ethernet receive thread priority to 1 higher than stack priority. Bugzilla #1760
6. Fix number of bytes written on bootstrapper flash operation. Bugzilla #1773

2. Fixed tcTelnetd class to comply with RFC 854 (control characters) and RFC 857 (support of remote echo control). Bugzilla #1634
3. Used netif_access to locate certain fields in a netif structure. This makes the Network library independent of the following lwipopt.h settings: LWIP_DHCP, LWIP_AUTOIP, LWIP_SNMP, LWIP_IGMP, LWIP_NET_HWADDRHINT. Bugzilla #1647
4. Added set_timeout() method to tcDspNetClientHttp to adjust the default HTTP timeout, if required. Bugzilla #1673

1. Added netif_access function to the lwIP library porting layer. This allows the Network library to access netif structures regardless of the build settings used in lwipopts.h. Bugzilla #1647

1. Correct text and label drawing bug due to lack of correct text box calculation and bug with | operator of internal tcRect class. Bugzilla #1672

5. Updated DspMacros.h RECONFIG_CLOCKS MACRO to only allow changing CPU speed, correctly handle speeding up or slowing down CPU speed, and correctly identifying MityDSP-XM memory topologies in all scenarios. Also added harmless write to FPGA to ensure FPGA DCMs are locked following a PLL reset (if it was required). Bugzilla #1253
6. Corrected error in LVDS interrupt service routine that was allowing stalls to occur under heavy load. Bugzilla #1281

1. Modified tcDspNetClientsHttp to provide support for secure connectios (HTTPS). This is accomplished through use of an SSL "helper" class based on the pure virtual base class tcDspNetClientsSslHelper. This allows applications that do not require HTTPS to not include the overhead of the XySSL library. Bugzilla #1255
2. Worked around bug introuduced by TI with Code Generation Tools 6.1.2. Their own "errno.h" header must be included after any DSP/BIOS header files. Bugzilla #1283

2. Fixed bug in FAT_open where it was returning error codes other than -1. The BIOS runtime assigns the return value from FAT_open to the file descriptor in the _ftable array. It uses the magic value -1 to determine if the entry if free. Bugzilla #1279

1. Corrected error that was causing all application FPGA images to get written to the FLASH location defined for the first application. Bugzilla #1265
2. Removed check that was only allowing application FPGA images to be written to FLASH bank 0 for the MityDSP-Pro. Bugzilla #1265

1. Modified build procedure for compatibility with TI's new Code Generation Tools (v6.1.2) Bugzilla #1284

1. Corrected stall in tcDspQdma (impacts MityDSP-Pro only). Bugzilla #1207

1. Fix scroll bar enable logic in the tcGuiListBox class. Bugzilla #1183

1. Added parameter to default .ini file to enable Ethernet features by default. Bugzilla #1187
2. Corrected cut and paste error between BlinkLeds and SendArp threads. Bugzilla #1204

1. Separated lwIP (3rd-party) library from the MityDSP network library. Imported the latest lwIP code baseline and re-wrote the porting layer. The lwIP source code and project file is now provided in all MDK distributions so end users may modify lwipopts.h (config file) as needed and rebuild the library. Bugzilla #317
2. Combined the network drivers and network interface support from the previous Net library and combined it with the Clients, Httpd, Wins, and Telnetd libraries. Some include path, library dependencies, and application code changes are required. See the FAQ's for detailed porting instructions. Bugzilla #317
3. Re-architected the network interface layer to improve significant inefficiencies in the previous design. Bugzilla #1058
4. The new architecture also addressed issues with (now unnecessary) intermediate ring buffers. Bugzilla #1055
5. New driver code maintains strict adherence to TI's SPRU656, Cache User's Guide. This addresses cache coherency issues reported with the previous code. Bugzilla #1057
6. HTTP read_buffer timeout was reduced. Corrections were also made to both HTTP code and lwIP which should prevent future deadlocks. Bugzilla #1024

1. Separated lwIP (3rd-party, open source) code from the remaining Network Library. Full source code and project file now provided in all MDK releases to allow user customization of lwIP library (usually via changes to the lwipopts.h file). Source code baseline captured from lwIP CVS head as of 12/11/2007. Bugzilla #317
2. New lwIP code addressed issues with the first packet to a new address being lost, possible data loss in tcp_receive, and a stall when under heavy IGMP load. Bugzilla #688, #964, #1067

2. Fixed wrap around bug error in tcDspCircBuffer class. Bugzilla #1062 Bugzilla #293
3. Added pre-initialization function _cl_int00 to the library to address issues with non-initialized global variables. The ISO standard requires these variables be set to zero, but the TI compiler is non-compliant (and requests to TI to address the issue were denied). While all MityDSP code does not depend on this feature, some 3rd party or legacy code does. Note that use of this function is required with the 3rd-party lwIP library! See the core library documentation for detailed instructions on using this function. Bugzilla #1093
4. Fixed tcDspTouchScreen class to initialize touch semaphore in constructor. Added method to retrieve tcDspTouchScreen touch semaphore. Bugzilla #1101
5. Corrected error in QDMA processing which could cause DMA transfers to stall. This impacted only the MityDSP-Pro. Bugzilla #1139

1. Removed obsolete DspRtc.cpp and DspRtc.h files from MDK. Bugzilla #950
2. Rather than write directly to a frame buffer, created a tcDspDisplayDriver base class to provide a consistent interface to all display devices. Derived the specific class tcDspQvga16 from this base class to support a quarter VGA 16-bit color LCD panel. Modified tcDspDisplay to interface to the new tcDspDisplayDriver base class. Bugzilla #928
3. Added the ability to register an ISR callback in tcDspGpio. This is more flexible and consistent with other core library classes. The existing semaphore based notification is still supported. Bugzilla #927
4. Added tcDspTouchScreen class to support for 4-wire touch screen overlay. Bugzilla #641
5. Modified tcDspDisplay class to use new DMA interface to frame buffer. Bugzilla #640

3. Added the capability to specify multiple CCD readout code instructions (up to 8). Added the ability to specify the sequence that each up these (up to 8) sets of readout codes is used when a multiple image acquisition is being performed. This sequence can be up to 16 long and repeats when it reaches the end. Bugzilla #959
4. Modified the temperature and cooling thread to use a PID loop to drive the CCD temperature to a target value while still enforcing maximum temperature rate of change limits of the device. Bugzilla #958

1. Modified tcDspFlash to not return bank select to zero if compiled for the Bootstrapper. This fixes an issue where FPGA images outside of FLASH bank zero could not be loaded. Bugzilla #926

2. Moved default application ID to the configuration screen and only downloaded it when the configuration datai was sent to the MityDSP. Bugzilla #957

1. Modified tcDspFlash to attempt to complete a read request even if bank selection fails. This supports the Bootstrapper, which must still read from FLASH before firmware (and the bank selector is loaded). An error code is still returned. Bugzilla #911

1. Rebuilt Bootstrapper to use latest tcDspFlash, which will complete a read request even if bank selection fails. Note that the FLASH bank should already be positioned in bank 0 when the Bootstrapper runs. Bugzilla #911

1. Allow "EDMA_OPT_PRI_ANY" to be passed into tcDspQdma functions as a valid priority. This will cause the tcDspQdma class to first attempt to obtain a hig-priority channel, and if this fails, attempt to obtain a low-priority channel. Bugzilla #868
2. The constructor in the tcDspDacTlv5610 class was not waiting for DAC initialization to complete before de-asserting chip select. This has been corrected. Bugzilla #802

6. Removed unnecessary semaphores in tcDspFirmware which could have caused a deadlock if pended on in an ISR. Bugzilla #689
7. All tcDspFlash operations return bank select to zero, reducing the chances of a reset starting from the wrong FLASH bank. Bugzilla #680
8. Fixed error in tcDspIntDispatch that allowed the software to be susceptible to spurious interrupts. Bugzilla #653
9. Added an optional user parameter to all existing callback functions in order to allow an application to provide an arbitrary value when the callback is activated. One potential application is to register a "this" pointer so a member function of a class instance may be dispatched as a callback. This change impacted tcDspAdcBase, tcDspCounter, tcDspI2C, tcDspPulseIntegrator, tcDspRamBlock, tcDspSerial, tcDspSpi, tcDspTimingGenerator, and tcWatchdog. Bugzilla #618
10. Added tcDspThermBase class to provide a consistent method of computing and storing temperatures for thermistor devices. Also added derived class tcDspThermERTJV1G ispecifically for ERTJV1G devices. Bugzilla #617

1. First external release of the Critical Link Camera support library.

1. Corrected error in LWIP that would allow a thread to hang indefinitely if the memory allocated to TCP messages was ever exhausted. Bugzilla #864
2. Fixed an internal bug in DspNetClientHttp which was miscounting the number of characters returned by a server in response to a query, sometimes resulting in a communications failure. Bugzilla #803
3. Added GetPhyType() and GetPhyStatus() methods to tcNetDrvr_B class to provide information on the type of PHY in use, and the status of the link. Bugzilla #676
4. Added assertion to sys_thread_new to ensure that all LWIP threads are created at a lower priority than the stack itself. Bugzilla #675
5. Correct tcp output longevity problem associated with continuous transmission of packets on a maintained tcp socket that may include odd length packet sizes. Bugzilla #622
6. Correct return code for send() calls of tcp sockets that employ MSG_DONTWAIT or the IO_NODELAY ioctl and are able to send some (but not all) of the requested message block. Bugzilla #591
7. Original LWIP code declared some variables as "long" or "unsigned long". On the 67xx a "long" is 40-bits, rather than 32. These declarations have been changed to int32 or uint32. Bugzilla #517

1. Fixed problem with timeouts due to the use of the time() function, which is not functional when the emulator is not present. Bugzilla #751
2. Corrected potential hang during HTTP operations by providing a timeout. Bugzilla #529

1. Added additional diagnostics and status checks to catch failed FLASH writes. Bugzilla #668
2. Updated maximum firmware size and other configuration block checks for the MityDSP-XM version. Bugzilla #638
3. To support firmware debug, the MityDSP Bootloader application monitors the serial port cores and re-initializes them if it detects that a new version of firmware has been downloaded via the emulator. Bugzilla #589
4. Allow Application Data sections with zero size. Bugzilla #533
5. Added advanced command ("fwrev") to print out revision information for selected firmware cores. Bugzilla #513

2. Provided software access to new firmware base-module features (base module version, watchdog, scrathpad memory). Bugzilla #496
3. Made sure that tcDspConfig and Bootloader handled conversion of older FLASH configuration blocks in exactly the same manner. Bugzilla #425
4. When the McBSP chip select scheme was modified as part of MDK 1.9, an error was introduced where chip select could be released too soon following an attempt to write to a device through the McBSP. This caused certain devices (such as the DAC7616) to behave in an unreliable manner. The McBSP status register is now properly checked to ensure that all bits have been written prior to releasing chip select. Bugzilla #424

1. Corrected LOG_printf with too many parameters (caused a garbled trace log entry in the debug library). Bugzilla #397
2. Added Non-Blocking support for sockets api send() call (lwip_send). If the socket is NONBLOCKING (via ioctl) or is send() uses the MSG_DONTWAIT option, send() will return immediately if there is no buffer space left in the stack (EWOULDBLOCK condition) or the socket has a terminal error condition (e.g., has been reset or closed by the peer, etc). Also added needed support for getting the errno, as well as adding a lasterr(int sock) method for thread safety as well as use the TSK_seterr() method. Bugzilla #464

1. Corrected potential hang during DNS lookups. Bugzilla #497

1. Corrected issue where multiple MityDSP's starting at once could end up communicating to each other, rather than the Downloader GUI. This impacted Ethernet connections only. Bugzilla #488

1. Added "-mi10000" compiler switch to all libraries to ensure that interrupts may not be disabled by the compiler for more than 10000 clocks (100usec @ 100MHz, or 50usec @ 200MHz). Bugzilla #408

1. Added class (tcDspFpgaIir) to control the Quad Infinite Impulse Response (IIR) FPGA core. Bugzilla #360
2. Modified tcDspParserBase and tcDspParseIHex to allow portability to Windows(tm) environment. This allows the same parser code to be used on both sides of a PC to MityDSP interface. Bugzilla #371
3. Added a user parameter to the parser callback in tcDspParserBase. This allows the application to provide information or additional parameters to the parser callback. Bugzilla #372
4. Modified the SetWaveformSamples method in tcDspAwg to account for discontinuous waveforms properly (e.g., a ramp). The change is backwards-compatible with the initial implementation, which only allowed for continuous waveforms (e.g., a sine). Bugzilla #382
5. A provided type definition to read ADC and SPI FIFOs was 5-bytes long instead of 4-bytes. Using this structure with DMA transfers would cause incorrect data to be read. The structure size has been corrected. Bugzilla #399
6. Reboot hanging up, Level 1 cache needed to be flushed. Bugzilla #401
7. Support new interrupt vector mask. This allows interrupts to be installed and enabled in any order. Bugzilla #327

6. Added class to support the TLV5610 DAC via the McBSP interface. Added a base class for DACs using the McBSP for commonality with the DAC7616. Bugzilla #340
7. Removed obsolete tcDspChipsel class. The tcDspOutputLatch template should be used in all cases. Bugzilla #353
8. Added convert_time methods to tcDspRtcBase to allow conversion between a tsCLTime structure and seconds since the start of the current epoch. Bugzilla #347
9. Updated the tcDspAdc8343 class with some small enhancements and to fix a minor bug (setting the "flip bit" - for 2's complement output - was not being done in the constructor). Bugzilla #342
10. Corrected corrupted core name text in tcDspFirmware.h. Only an aesthetic bug. Bugzilla #341
11. Fixed tcDspAdcBase class to not clear BurstComplete when setting other control attributes (e.g., Enable, FIFOPack, channel mask, etc). Bugzilla #351

1. Changed TCP Window Size to 2920 (two full 1460-byte packets) in order to cut down on missed packets with servers capable of serving packets at the full 100 Mbps rate. Bugzilla #364

1. Alert GUI at initialization of bad config is detected. Implement all default values when creating a config for the first time. Completed remaining checks for bad board configiurations. Bugzilla #354
2. Added support for TCP image download, via the TCP_PROCESS command. Bugzilla #357
3. Worked around issue where a router was stealing the MityDSP's initial ARP and redirecting the Downloader GUI to an invalid location. Bugzilla #337
4. Added reset of EMIF and L1 cache flush to Bootstrapper. Also added a GEL file to perform an L1 cache flush when using the emulator. Bugzilla #359, 126, 282
5. Corrected error with non-existant parameters being parsed. Allowed HTTP downloads to be more forgiving of server errors. Bugzilla #365
6. Added board ID filters to Downloader GUI to limit connection to a range of board ID's when connected via Ethernet. Bugzilla #349
7. Modified Downloader GUI to write temporary files only to the startup directory. Bugzilla #355

1. Corrected issue in tcBootstrapper class that was allowing downloads to get corrupted. A cache operation was not being allowed to complete before copying the Bootstrapper to SRAM. Bugzilla #335

1. Rebuilt against Core v0.10.1 to address unreliable download issue. Bugzilla #335

1. Added tcDspBootstrapper class to reactivate CLUB Bootstrapper to load a new executable (effectively a software reset). Bugzilla #306
2. Added new include directory for CLUB files (inc/boot). The configsect.h header now lives in this area (removed from top-level inc). Bugzilla #315
3. Updated tcDspConfig to work with new v3 configuration blocks. Reads and internally converts v2 blocks to v3 format. Added support for multiple application data areas, retrieving the default application ID, and accessing a static copy of the full config block (always in v3 format). All previously existing methods are fully backwards compatible. Bugzilla #318
4. Added tcDspAdc8402 to support Burr Brown ADS8402 devices. Bugzilla #324
5. Updated interrupt handling code to deal with register race condition and force disabling of intergrator prior to reading data. Resolves intermittent errors seen during continuous operation. Resolves Buzilla #332

1. Corrected UDP/TCP checksum issue. Depending on buffer alignment, certain messages were sent with incorrect checksums. Bugzilla #316
2. Updated TCP Maximum Segment Size to be the more "standard" 1460 bytes, rather than 1024. This resulted in a small performance increase. Bugzilla #310
3. Version 0.6.0 added DMA capability directly to the net_drvr_b ISR. Unfortunately, the class to handle the DMAs (tcDspQDMA) is a singleton... a class that automatically creates an instance the first time it is called. The previous code did not guard against the ISR being the first caller, so creation could occur in the ISR. This is illegal, since malloc/new operations are not permitted in an ISR. This resulted in corruption of one of the internal locks around heap, which manifested itself downstream with various unexpected behaviours. This is now corrected. Bugzilla #319
4. The LWIP stack now sends a gratuitous ARP at initialization, and whenever its IP address is changed. Bugzilla #320
5. DHCP could fail because of a check to ensure that the IP address offered by a DHCP server was not already in use. The DHCP server itself could respond to the ARP probe of the address, making the MityDSP think the address was invalid. The extra check has been removed. Bugzilla #321
6. Corrected bug for out-of-sequence FIN handling (TCP messages were corrupted when the remote side closed the connection before LWIP finished processing all the data). Bugzilla #325
7. Fixed LWIP code for producing a gratuitous ARP. The ARP is actually broadcast to all users instead of just itself. Bugzilla #328
8. Fixed deadlock in LWIP code that could occur under heavy load. A queue was written with an indefinite timeout by the same thread that was responsible for reading the queue. If the queue became full in the meantime, the thread would lock up. Bugzilla #329

1. Now known as CLUB (Critical Link Unified Bootloader). The previous Bootloader is split into a separate Bootstrapper and Bootloader. The Bootstrapper runs in SRAM and is responsible for copying and activating SW and FPGA code. The Bootloader is now a full fledged application with enhanced features (inluding ethernet download) Bugzilla #75

1. Added modem controls to tcDspSerial Bugzilla #260
2. Added "Flip Bit" (2's compliment) support to tcDspAdc8343 class. Bugzilla #288

4. Added baseline version of tcDspPulseIntegrator Bugzilla #215
5. tcDspAdcBase class modified to handle 8 channel devices. The existing tcDspAdv8343 class will now work with ADC8344 devices. Bugzilla #256
6. Modified tcDspFlash so only BOOTLOADER-specific code is to enable bank 0 writes. Bugzilla #301
7. Corrected tcDspFlash to work properly with RoHS parts. Bugzilla #297
8. Added a base class for generic parsing capability (tcDspParseBase), as well as a derived class to parse Intel HEX files. Bugzilla #298
9. The setBank method of tcDspBankSelect now returns "true" only if the proper bank is indicated by the firmware. Bugzilla #307

1. Added rudimentary NTP client. The client will return a time_t value representing the seconds since the start of the epoch as set by the NTP server, ignoring network delays. Bugzilla #281
2. Added ability to retrieve nameserver addresses from DHCP server and store them in the netif data structure. Bugzilla #270
3. Changed FD_SETSIZE to increase number from 16 to 64. Bugzilla #300
4. General clean-up of net_drvr_b code. Updated MII read routines to match firmware implementation. Scheduled DMA transfers directly within ISR in an attempt to improve throughput (requires one less context switch). Bugzilla #245, #249, and #302
5. Add PHY address as a parameter to GetMIIRegister and SetMIIRegister in net_drvr_b. Default of 0 provided for backward compatibility. Bugzilla #308

1. Added ability to get host IP from nameserverBugzillia #280
2. Added a simple HTTP/1.0 client capabilityBugzillia #286
3. Added minimal HTTP/1.1 support so that GET requests may select a byte range to transfer. Required to support code download via web servers. Bugzilla #296
4. Corrected memory corruption error in the read_line method of tcDspNetClientHttp. Bugzillia #303

1. Corrected a stall in tcDspStepper due to velocity being allowed to go to zero. Bugzilla #278
2. Corrected documentation errors with tcDspAdcBase, tcDspCounter, tcDspI2c, tcDspSpi, tcDspPulseIntegrator and tcDspRamBlock. Bugzilla #272

1. Bugzillia #273

1. Updated tcDspQDMA class to allow usage directly from an ISR. Bugzilla #187
2. Added tcTmp0506, a class to provide access to the TMP05/06 temperature sensors. The class is derived from tcDspRamBlock. Bugzilla #252
3. Added a base class (tcDspRamBlock) to support the RAM Block interface to be used by simple MityDSP firmware cores. Bugzilla #251
4. Fixed DspConfig GetAppDataOffset() and GetAppDataSize() methods to return unsigned integers as they now return byte offsets and sizes instead of sector offsets and sizes. Resolves Bugzilla #243.
5. Added tcDspRtcM41T81, a derived tcDspRtc class to support the M41T81 real-time clock. Bugzilla #242
6. Corrected issue with some code usage examples being cut-off in the documentation Corrects Bugzilla #241
7. Added tcDspDac8534 to provide support for the DAC8534 digital-to-analog converter using the generic SPI interface. Bugzilla #238
8. Added tcDspSpi, a generic I2C interface (transmit only) Bugzilla #233
9. Added tcDspI2c, a generic SPI interface (transmit only) Bugzilla #231

2. ADC Base class rearchitected to better support family of high speed ADC's. Superset of features added to base class, while derived classes disable features that don't apply. Rather than making the end user register an interrupt handler, the interrupts are automatically handled, and hooks are provided to allow applications to add specific functionality by registering ISR callbacks. Resolves Bugzilla #196.
3. Added derived high speed ADC class to support the 8343 ADC. Resolves Bugzilla #236.
4. Updated Real-Time Clock (RTC) class to allow support for multiple devices. Old DspRtc replaced with a base class (DspRtcBase) and a derived class for the DS1305 RTC (DspRtcDS1305). Resolves Bugzilla #222.
5. Fixed issue with chip select not being released properly within DspTlv254x. Replaced old chip selector interface with the more flexible DspOutputLatch method. Resolves Bugzilla #213.
6. Added the option to have DspError report timestamps in msec since boot, rather than HH:MM:SS (which is only valid when running the emulator or with a RTC and a custom clock routine). Resolves Bugzilla #216.
7. Stepper interface class updated after final baseline testing with firmware class and' available hardware. Move, Reset, Sleep, Abort, SetParams, Locate, Seek, and count/position commands tested with TS1 and TS2 terminal switches. Overshoot/iterate logic for locating switches TS3-TS7 (not terminal switches) not tested with this delivery. This drop Resolves Bugzilla #176.

1. Updated DspFlash to use the Common Flash Interface (CFI), allowing this class to be used with multiple Flash devices. Resolves Bugzilla #143
2. Added DspPwm to provide interface to new PWM core module. Resolves Bugzilla #101
3. Removed call to log error file name/line numbers to LOG_obj in DspError. replaced with a application-defined (optional) callback. Resolves Bugzilla #185
4. Fixed bug with DspSerial that can result in stalls on transmits. Resolves Bugzilla #186
5. Added Beta version of Stepper interface class. This drop is an initial build to address Bugzilla #176. However, complete functionality is not yet implemented. Supported methods include the ::Move command and the ::SetPulseParams. Methods involving locating or seeking switch positions are unimplemented; therefor the associated Bug is not yet resolved.

1. Fixed Bugzillia #88 - Applications hang or crash if the Ethernet cable is unplugged while an active TCP connection exists.
2. Added an assertion check if a thread is registered with the TCP/IP stack which has a higher priority than the TCP/IP thread.
3. Added a field to the tsDSPNetStackInit structure so that the TCP/IP priority may be application adjusted by the DSPNetStackInit() function. Previously the TCP/IP thread was hardcoded to be priority 5, which can cause problems since all threads which access the socket interface must be a lower priority than the TCP/IP thread.
4. Added a field to the tsDSPNetStackInit structure so that an application specified assertion hook function may be specified. This allows users with the binary only library to trap LWIP assertions in debug builds without having the source code to place a breakpoint in. Note: When an LWIP assert is called, the function jumps to the DSP BIOS abort() function and the callstack is not available in the debugger. This hook allows the user to see the call stack and/or the assert message with file name and line number where the assertion occured.
5. Synched up with LWIP CVS. Two fixes came from the synch...
   File: core/tcp_in.c CVS Version: 1.57
   Description: Duplicate FIN ACK race condition fix by Kelvin Lawson.
   Note: Did not take version 1.56 changes... ...Introduced cc.h formatters and removed SO_REUSE from transport layers.
   File: core/tcp.c CVS Version: 1.50
   Description: Remove PCBs which stay in LAST_ACK state too long.
   Note: Did not take version 1.49 changes... ...Introduced cc.h formatters and removed SO_REUSE from transport layers.

1. Added DspIntDispatch to provide the capability to have multiple ISR's on each of the external interrupts (4-7). Bugzilla #92.
2. Updated DspGpio and DspSerial to use DspInterruptDispatch.
3. Added support for automatic interrupt level and vector determination in DspGpio and DspSerial (new firmware feature).
4. Added support for reading/writing the new interrupt vector masks in DspFirmware (part of Bugzilla #92).
5. Also added support for reading the automatic interrupt level and vector information from each core to DspFirmware.

1. Updated net_drvr_b to use DspInterruptDispatch (Bugzilla #92).
2. Added support for automatic interrupt level and vector determination in net_drvr_b (new firmware feature).
3. Updated net_drvr_b to use local core interrupt enable, rather than global interrupt enable, when performing DMA transfers (Bugzilla #98).
4. Made DMA usage in net_drvr_b to be run time configurable via optional constructor parameters. Also allowed DMA receive thread priority to be user-modified.
5. Corrected unitialized variables in TCP stack that would sometimes cause a stall if a TCP packet was sent before one was received.

1. Added DspGpio core to provide a general purpose digital I/O capability.
2. Corrected potential compilation errors in DspSerial.h.
3. Added full baud rate support in tcDspSerial. EMIF speed and type of UART (hardware or MityUART) is sensed and used to create proper baud settings.
4. Added support for hardware flow control in tcDspSerial.
5. Added tcDspFirmware class to provide generic firmware access methods to report version information, set global interrupt masks, report EMIF clock speed, etc.

1. Added board configuration that is stored in flash. Separated FPGA images
2. into boot and application. Added peek and poke commands. Added support for
3. download of board configuration from Bootloader GUI and execution of peek and
4. poke commands from the Bootloader GUI.

1. Modified stack memory initialization to allow for runtime configuration of the amount of buffers that will be available for the stack rather than only having the predefined buffer space available. This is a backward compatile fix. Bugzilla #42, #40 & #44
2. Added task registration functions so that a task created through the standard TI runtime functions can safely access the network stack. This task registration function may be used in place of using the LWIP task creation functions. This is a backward compatile fix. Bugzilla #40
3. Added a pre-IP address udp port hook function to allow use of custom bootp like protocols. Bugzilla #38
4. Fixed array overflow in mem.c. Buzilla #44

1. Updated network interface driver B to not sleep 1 ms following each packet receipt.
2. Changed LWIP options to use 512 KBytes for buffer space, increased TCP window sizes in order to improve TCP and UDP throughput.
3. Updated LWIP sys_arch.c to correctly handle timeouts structure in multi-threaded environments. Timeouts structures are no longer keyed by priority, but instead by task ID number.
4. Turned on LWIP statistics.
5. Enabled DHCP in LWIP.

1. Fixed incorrect core.pjt file, so that the new tcDspQDMA class actually gets built into the library.

1. Added tcDspQDMA class to Core library.
2. Added MityDspDownloader aplication to the tools directory.

1. Added MityDSP network driver B to net_drvr section. Includes DMA based interface to 32 bit FPGA ethernet core.

4. Fixed namespace error in the definition of the runtime version check variables.
5. Added a tcDspSerial demo project.
6. Changed includes within the headers so that you do not need to have C:/MityDSP/x.x/inc/core in your projects include path. You now just need C:/MityDSP/x.x/inc in your path.
