- MW 09:00 AM Software Development: RE: Kernel documentation
- Hi Dennis,
It doesn't look like there is a uPP driver for the linux / ARM side available from TI at the moment. They do have drivers for DSP/BIOS, which might work if you wanted to use the DSP core of the OMAP-L138. It may not be to...

- Ran the make's using the existing .config (make menuconfig, make uImage plus environment fluff).
Hit a problem with the kernel compile.

I'm using the gdbserver that I built since my company has me behind a firewall and won't recognize the mityOmap as an authorized machine. :-(
Anyway, I didn't see anything related to multiple threads in Eclipse and how to sw... - MW 04:55 PM Software Development: RE: dsplink debugging issue
- Rich,
Are you using the gdbserver that you built or the one from opkg? You should be able to do thread level debugging. I'll see if I can reproduce. Keep in mind on the eclipse context that multiple threads can be running, and if y... - RB 04:07 PM Software Development: RE: dsplink debugging issue

I think I have a handle on what's going on.
The system seems to go into limbo immediately after a call to pthread_create() inside a function called _NOTIFY_Init in _notify.c module, which is part of the dsplink library. It se... - RB 03:22 PM Software Development: RE: dsplink debugging issue

The app is the "message" sample app provided by TI in their dsplink release. It runs to completion normally when executed outside of the debugger and communication between the ARM and DSP appears to be working correctly based... - MW 02:18 PM Software Development: RE: dsplink debugging issue

If you are trying to use the EMIFA on one of the chip select spaces for the FPGA with custom FPGA code, you will need to write a kernel module driver to provide access to the physical memory in linux. There is a "pretty go...

Sounds like you need up update the uboot image on that board. I think you got that one before the others and there were some changes
made to uboot for this issue. You will want to run

I think the key thing will be to ensure that you are using the same BIOS settings (the .tci/.tcf file) as the DSPLink is configured for. Specifically, the load addresses / segments sizes are consistent between your builds. The...
