OMAP L138 or CCS suddenly stops working

Johannes Lang

Part Number: OMAP-L138

Hi,

I am developing on the OMAP L138 LCDK evaluation board and all the code in use is bare metal C.

Until last week everything was working fine. But now after some short time the processor jumps to strange addresses.

In the disassembly I can see that at such addresses either IDLE or NOP is written and therefore the processor gets stuck.

My setup:

Windows 10
XDS200 Debug Probe
- TMSEMU200-U
- Blackhawk
OMAP-L138 DSP+ARM9 Development Kit (LCDK)

What I obtained is, that I can step through the code for approximately two functions.

In my "Set Direction" function the values passed to it are totally different to the ones I have passed.

The problems I am facing are similar to the one described in this post: https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/114816/ccs-4-2-xds100-suddenly-stop-working . I also tried the suggested solutions - however nothing works.

I am really desperate at the moment as I am really do not know what to do.

Hello,

Does this happen when you just load and run the application and then the application just gets stuck somewhere? Or does it happen during debugging (setting breakpoints and source stepping)?

Thanks

Hi Ki, this happens both times. Whats strange about it is that it worked before. Also I used a Starter Ware Project to test the general function and there it works totally fine. I know starter ware is not supported anymore. Do you have an example or pre configured project for bare metal programming of the OMAP? I assume that there is something wrong with the project itself.

Also I can confirm that if I create a new Hello World project with the code composer studio everything works fine.

Yes, it could be some issue with the specific project or some dependency for it:

I will need to bring this attention to the device experts. They can answer best

Thanks

Hi Johannes,

Please find example projects from this page: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/975156/faq-omap-l13x-c674x-resources-and-faq. Please look for "Where are the PDK example projects?" from the page.

To use these sample projects, you'll need to install the Processor SDK RTOS for OMAP-L138.

Jianzhong
