DSP Bios crash hook function.

Other Parts Discussed in Thread: DM3730

I'm using the Beagleboard XM (DM3730), my application has a bug that causes the dsp to crash,

is it possible to hook a function to handle the crash and send a message to the arm ?

can I send the call stack ?

how ?

 

I can't use the simulator because the crash happens after a long time,

running on the board.

    Please take a look in the C64x+ CPU & Instruction Set Reference Guide for the TMS320DM3730. Find section 6 on CPU Exceptions and see if some of the DSP's error checking exceptions will help you.

    BIOS has support for DSP exceptions, but I am not sure they would be sent to the ARM. The nice people at the BIOS forum may know better, so we will have this thread moved there for you.

    Motti, what's your SW stack look like?  Are you using BIOS on the DSP?  Which version?  How about other SW (and versions) like DSP Link, DSP Bridge, etc.?

    I'm not sure there's an out of the box solution for you, but knowing more about your system might spark ideas from others.
