raw logs show unknown error

I am currently chasing a memory corruption error and am having trouble understanding the errors in my raw log file.

I am using a custom board with an OMAP L138, Linux on the ARM and DSP/BIOS 5.41.13 on the DSP.  I am using CCSv5  Compiler 7.3.4

The raw logs show the following errors numerous times when I am running -

"PRD begin- <unkown handle> (0x00000000)

Unknown event ID 65535"

These show up several times in the log file prior to my memory corruption.

Sometimes I will also see an SWI - unkown handle. 

 

Please advise,

Thanks,

Joyce

    Hi Joyce --

    It appears that your LOG buffers are also being corrupted.   The BIOS LOG module places event ids and arguments into a circular buffer in memory.   "Unknown event id" means that the event id is not a legit value.  Event ids are integers between 0 and 12-15 (I forget max).   "Unknown handle" means that the PRD handle is not a valid PRD address.  

    I think that your LOG buffers are being corrupted by your application somehow.
