Problem with (ARM + DSP) system in OMAP-L137 EVM

Other Parts Discussed in Thread: OMAP-L137

Dear Sir/Madam,

I developed a mixed system including ARM processor and DSP processor. ARM receives data from audio device and sends it to DSP via DSPLink. I customized the read/write example for my purpose that is in the OMAP-L137 package. This example uses PROC_READ and PROC_WRITE functions of DSPLink library to read from and write to DSP memory and PROC_LOAD to load an out file on DSP. I have a problem as follows:

When ARM loads a small program (.out file) on DSP, all things are OK and system works well. However, when I compile a complex program and want to load it via ARM on DSP the system hangs. I think the program is not loaded on the DSP. On the other hand, the PROC_LOAD does not return any error status.

What is the problem?

 

Thank you in advance
