SW 10:12 AM Software Development: RE: uPP/DMA registers: Shahzad, I have not found uPP drivers for the ARM in linux. My suggestion in developing them is to read the TI uPP manual, get it working in loopback mode and them transition that to you application. Be sure you set the pin mux for th... Scott Whitney

MW 06:25 PM Software Development: RE: TI C6EZAccel library with MityDSP Platform - OmapL138: Hi Michele,
If you would like to use the full TI DVSDK (including C6EZAccel), you can install it from TI (along with the Code Sourcery tool chain). You can use TI's libraries and filesystems, etc. The only thing you will need to do ... Michael Williamson
MC 06:05 PM Software Development: TI C6EZAccel library with MityDSP Platform - OmapL138: Dear Sirs,
does anybody there managed to install and use the C6EZAccel library for the OMAPL138 processor, using the MityDSPL138F carrier board?
It's said to be a library that can abstract Signal Processing libraries of the C647 DSP ... Michele Canepa

MW 10:19 AM Software Development: RE: uPP/DMA registers: If you are not using the on-Board NAND in your design (e.g., booting to a RAMDISK or off of MMC or something), then the EMIFA would probably work. Though, you may still have to roll up a kernel module/driver to fetch the data (I would r... Michael Williamson
SM 09:52 AM Software Development: RE: uPP/DMA registers: Hi Mike,
Thanks for the prompt reply. Actually the data stream is from an H.264 encoder in an FPGA, so im not sure if VPIF would be helpful here. Thats why I was looking for a uPP driver. The other option seems to be the EMIFA interfa... Shahzad Malik
MW 08:18 AM Software Development: RE: uPP/DMA registers: Hello Shahzad,
Unfortunately, there is still no UPP driver available. Have you looked at pushing the data in using the VPIF? Supposedly, there has been some work done by TI to push a couple of different modes of camera data using th... Michael Williamson
SM 04:11 AM Software Development: RE: uPP/DMA registers: Hi Mike,
I am looking for a uPP driver for linux and I was searching around when I came across this thread. I know im replying to a very old thread, but I noticed that you mentioned that critical link does not have a uPP driver yet. F... Shahzad Malik

KF 12:21 AM Software Development: RE: FS Corruption due to dropping power: Hi Mike,
Thanks for the reply. This is reasuring that it is a FS corruption problem. I have instigated a read only file system, based on your notes, and its seems to work, as in everything is mounted read only, and the application st... Keith Fletcher

MW 12:57 PM Software Development: RE: Starterware EMIFA to FPGA example code: Hi Emmett,
Are you using linux or starterware? On starterware, if you are launching from u-Boot (which configures the EMIFA to have some nominal timings for CS5 space), then all you need to do is perform memory read or writes to 0x66... Michael Williamson
EB 12:37 PM Software Development: Starterware EMIFA to FPGA example code: Hello,
I have used your "EMIFA_iface" VHDL example to make a simple FPGA to test by reading/writing to registers routed to the expansion I/O on the base board.
I need example C code to make the EMIFA transfers.
In the Starterware, I... Emmett Bradford

MW 06:31 PM PCB Development: RE: RTC Battery Drain: Hi,
Wanted to follow up on this. We have seen RTC battery drainage, but at the time we looked at it we were using Revision A silicon OMAP-L138 parts, which had some errata about power leakage that was fixed in the Revision B (standar... Michael Williamson
MW 06:28 PM Software Development: RE: FS Corruption due to dropping power: Hi Keith,
I have seen these symptoms before, and I'm pretty sure it's filesystem corruption related (I suspect udev related, not installing the /dev/ttyS* files due to a corrupted cached tarball of /dev which is by default stored off ... Michael Williamson

KF 04:29 PM Software Development: FS Corruption due to dropping power: Hi, We are developing a system where the user is unlikely to power down gracefully, even if asked to do so and ultimately intend to use a read only file system. However in testing we have not done this and have been dropping power to swi... Keith Fletcher

MW 09:46 PM PCB Development: RE: SODIMM Pin 53 ...: SPI1_SCS0 is indeed connected to that pin on the module. It is also connected to the chip-select on the on-board SPI NOR FLASH, which is used for loading the first stage bootloader (UBL) as well as u-Boot. The pin was brought out to th... Michael Williamson
TC 09:33 PM PCB Development: SODIMM Pin 53 ...: (Posted on behalf of a customer)
The datasheet for the MITYDSP-L138F shows Pin 53 as reserved, however the Industrial IO board uses it for SPI1_SCS0. Why does the datasheet show it as reserved?
Thomas Catalino

MW 07:40 AM Software Development: RE: StarterWare question ...: Quick note. The new u-Boot command to load up the Starterware image was "bootelf" not "loadelf". I've corrected the wiki page. Sorry for the confusion (I was trying to post that before having to climb on an airplane!). The u-Boot im... Michael Williamson

SP 02:56 AM Software Development: RE: StarterWare question ...: see [[StarterWare]] Stéphane Peter

MW 02:33 PM Software Development: RE: StarterWare question ...: Hi guys,
Just wanted to give you a heads up that we've been able to get the EVM UART echo example in the TI startware up and running here at Critical Link. We've been able to load with with the debugger/emulator as well as load the E... Michael Williamson
