Other Parts Discussed in Thread: OMAPL138

Hello,

I changed the code from the linux dsplink mplist sample on my custom OMAPL138 board.I added HWI SWI and TSK to my dsp project.When I called PRO_load function in gpp application,the gpp stopped and the dsp application executed.In my opinion,the gpp application shouldn't stop,it should continue running to next step(In my app is PRO_start()).Did the system collapse when I call PRO_load?

How to solve the problem?

Thank you in advance.

I found a solution here:

http://processors.wiki.ti.com/index.php/Troubleshooting_DSPLink_configuration_issues#Problem:_I_see_a_crash_as_soon_as_I_run_a_DSPLink_sample.

Possible cause: There is an overlap in the configuration of timers on Linux and DSP/BIOS. This problem has commonly been seen on OMAPL137 and DA830 where the timer 0 is used by DSP/BIOS and Linux. In that case: Update the sample to change the BIOS timer to use a different timer. See a sample configuration to change to timer 1.

Clock = xdc.useModule(‘ti.sysbios.knl.Clock’);
Clock.timerId = 1;

Can anyone tell me where i can change that?
