Strange Behaviour on DSP-Bios project DM 6437

Heramb Kuwelkar

Hello,Currentlywe are doing a SPI driver for DM6437 using Mcbsp (refering spru943)section 2.9.We have been able to configure it properly and the transfer are happening.Our problem is

1)We have to step-in the code everytime to see the output.If i do "run" the controls goes to DSP-Bios instruction and hangs.So transfers do not happen at real time.

2)Also the control does not reaches to main() directly when we "Run" and gets hang at some DSP Bios instruction .But when we "step in" some DSP-BIOS instructions and then try then it reaches to main() properly.

Can you please let me know why this strange behaviour is occuring.Am i missing some settings related to DSP-BIOS or CCS that needs to be done.??

Is this your own hardware or the DM6437 EVM? It sounds like something is fundamentally wrong in your setup. Are you able to simplify your program to a point where you can run without things crashing?

Hello Brad

sorry for late reply.There was a problem with the GEL file which when we replaced,everything started working fine.

Thanks a lot

Hi Heramb

Can you share the code that supports the SPI in the DM6437 + required gel file changes?

Thank you,

Ronen
