- GS 12:01 PM Software Development: RE: Loading UBL and U-Boot
- Hi,
Thanks Tom. It works thanks to null modem cable.
Does fpga_pwm.ko use the pwm core in FPGA ?
Does ehrpwm.ko and davinci-pwm.ko are equivalent to fpga_pwm.ko but this latter offered more flexibiliy ?
If the application Ind... - TC 09:26 AM Software Development: RE: Loading UBL and U-Boot
- Gregory -
In the development kit there is both a small cable that adapts the dual-row header to DB9 and also a DB9 to DB9 serial cable, they both must be used together as the DB9 to DB9 is a null modem configuration. Perhaps you are ... - MW 07:37 AM Software Development: RE: Loading UBL and U-Boot
- Hello Gregory,
When you received the board, it should already have been programmed with u-Boot and should come up to that prompt on power up. All units are tested before they are shipped, so the unit should be working to that level. ...

- Hi,
I can't see BOOT ME using Terminal (115200 N 8)
the button on the board is S100 (Boot) ?
Do you cab loaded the Linux Kernel into the OMAP ?
I want to understand about fpga_pwm.ko. Does it controls the signal on the pins o... - MW 03:08 PM Software Development: RE: Loading UBL and U-Boot
- We've not tried using the serial flasher with the linux mono framework. It has only been tested using Microsoft Windows .NET framework.
For sanity, you might try a terminal program such as putty at 115200 and reset while holding the ... - (Posted on behalf of a customer)
I received the MityDSP-L138F Development Kit (80-000268RI-2A) today. I am unable to recevive "BOOT ME" via UART for loading UBL and U-BOOT on it.
I use the following command line : >mono sfh_OMAP-L... - MW 07:21 AM Software Development: RE: Using the EMIFA interface on the Mitydsp-1810
- Hi,
We use the EMIFA (16 bits) to interface to our FPGA on SOMS including an FPGA. The pinmux and initial chip select settings for the EMIFA are configured, by default, out of the u-Boot application (see "boards/davinci/mityomapl138/... - Hi,
I was wondering where in the linux source I should be looking to add changes if I wanted to use the EMIFA interface to communicate with an asic in 16-bit parallel, async mode. I assume there are pinmux and possibly chip select se... - TI 07:18 AM Software Development: RE: mtd->read (...) returned ECC error

Did you use the filesystem creation notes from the wiki [[Linux_Root_File_System]] ?
We have found that you need to use the pre-fill memory and write in page sizes
to keep the jffs2 filesystem correct.
Hope this helps..

We have one mitydsp L138 board which keeps coming up with these mtd->read (....) returned ECC error.
We have several other boards that boots without any errors.
This has been seen on other boards as well, but might have gone when...

- 6.1.9 is *really* old, Rich. Last time I checked, we are using at least 6.1.19 here. You might consider checking the release notes on the newer builds and see if any STL stuff is mentioned. I believe STL was "new" feature in 6.1.

- Hi Mike,
At the moment I'm using the 6.1.9 toolchain hosted on the PC side through CC v3.3
I'm primarily vectoring intrinsic types but there are a few places where I'm
vectoring something like:

- Hi Richard,
What version of the code gen tools are you using? If it's an older chain, TI may have already found/fixed it. You might cross post this on "TI's E2E Site":http://e2e.ti.com as well.
We have used the std::vector clas...
Has anyone used the standard template library vector class on the DSP side of the OMAP-L138?
I have a large memory intensive algorithm that is being adapted from a corresponding MATLAB
program and up til now have been using STL vec...

Are you using the same build of the kernel (e.g., the same .config file) as the one that is running?
Did you use the same toolchain for both builds?
I haven't seen this particular issue. Can you post your .config file th... - Hi,

That did it !
I now have a working kernel, that I have built. Onward now to getting the DSP stuff to work :)
Many thanks,

- MW 11:23 AM Software Development: RE: L138 UART and DSP
- Hi Andrew,
With the MityDSP-L138F, you have two options for UARTs: you can use one of the three UARTS provided on the OMAP-L138 processor, or you can use one or more UART cores (made available by Critical Link) instantiated in the FP... - Hi,
For the project that I am currently engaged in we have a remote ADC device that feeds data down a fibre optic link into a UART.
I want the UART to be read by the DSP which will then perform a variety of manipulations and calc... - MW 10:14 AM Software Development: RE: Kernel Hang

- Ok,
Sorry guys. I need to update the instructions on that page. The devel branch is no longer maintained, and you should always reference new work off of the master. The proper instructions, for the Industrial I/O board, should be ... - AH 10:02 AM Software Development: RE: Kernel Hang

I built the kernel as per the instructions here: http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Kernel
I have made no local changes, I can't get the vanilla one to work :)

Can you please identify where you got the kernel (is it from support.criticallink.com, arago, the TI PSP, or mainline?) and what commit point you are working with? You might also want to include the .config file so that we ... - Hi,
I have a MityDSPL138 in the industrial IO board. I have built a new kernel, (2.6.34-rc1) It hangs when I try to boot.

- Mike,
The new boards boot with the 2011-08-01 uImage. I still need to check if this image is backwards compatible with the older MityDSP boards.
Thanks,
Dave

- MW 11:16 AM Software Development: RE: Kernel Hang Anomaly
- Hi Dave,
I think you might want to use the uImage located in the release_2011-08-01.run file under MDK_2011-08-01/images/uImage. There are several bug fixes from the May 2010 release that may be causing the hang.
If that doesn't h...

Can you please post the complete text of the boot attempt, from the start of power up to the hang?
Also, can you please type "factoryconfig" as well as "config" and dump the results from u-Boot?
