Other Parts Discussed in Thread: OMAPL138

Iam currently using the hawk board containing OMAP l138 processor. I have downloaded the rCSL examples from link

http://processors.wiki.ti.com/index.php/QuickStartOMAPL1x_rCSL

I tried to use the examples present in it for OMAPL138..Iam using CCS4 and XDS100v2.

Processor goes to infinite run after executing the below function

// Intrinsic Function; Gain 'supervisor' privileges
_call_swi(ARM_PRIV_MODE_KEY);

Iam confused what may be the problem.I have even given some value corresponding to stack and heap in the CCS project, still problem exists..

Kindly help me in solving this issue.

Hi,

Talking to the person who did the CSL testing on the OMAP13x, he is not sure what is the problem here. He said that he had ran all the examples on both L137 and L138 using the Spectrum Digital and Logic PD EVMs; however, no testing has been done on the hawkboard.

Just out of curiosity, did you import the project or did you build your own project using the source files? This could be an issue if you did not include the assembly file to set up the stack for software exceptions, or if you did not execute the assembly file (should occur before main).

Hope this helps.

Thanks,

Tai Nguyen

Hi,

Can you please also let us know which version of the examples (1 or 2) you are using as well as which examples you notice this issue? Is the issue consistent on all the ARM L138 examples or just one or two?

Thanks,
Kevin
