J721S2XSOMXEVM: DSP Debugger Support for EVM

Part Number: J721S2XSOMXEVM

Tool/software:

Hi team,

I'm looking for a debugger tool with setup instructions for Vision apps DSP application with algo_graph Changes 

I'm able to debug the bare metal standalone DSP application using XDS560v2 debugger through CCS tool.
But I'm not able to boot A72 core through CCS.

Do we have any debuggers to debug the DSP application with Vision apps framework ?


Can you please support me to get the debugger setup for debugging tiovx graph application (where A72 will be host and C7x will be the target )  ?

    Hi Kiran,

    You cannot debug a72 code through ccs, I would suggest to use gdb to debug from the evm.

    To debug c7x target application using ccs you can enable debug build in the sdk and copy the debug firmware to ccs. Boot the evm and connect to ccs then select the c7x core from the listed cores in ccs and connect. Then load the symbols for that c7x core. 

    Since host and target is involved it is not straight forward to debug c7x firmware. if you want to debug a process_callback function of a kernel then find the address of that function in .map file and keep breakpoint at that location. Then when you run the application from A72 the process_callback will trigger and hit the breakpoint, after that you could able to see the source file in ccs which is currently executing.

    Regards,
    Gokul
