Part Number: TDA2PXEVM

Hello All,

I am currently working on the following usecase,

NullSource (A15)->Decode->VPE->Sync->Alg_A (DSP1)-> Display_M4 (IPU1_0)

 


But while running the usecase, I am getting the below error

[HOST] [EVE2 ] 58.035014 s: SYSTEM: SW Message Box Msg Pool, Free Msg Count = 1023

    Hi Shanthanu,

    [ 51.305543] remoteproc1: crash detected in 40800000.dsp: type mmufault

    This confirms there is some illegal memory access in DSP's algorithm. Please check this command to confirm this. 

    What does your Alg_A link do?

    cat /sys/kernel/debug/remorteproc/remoteproc1/trace0

    Bypass DSP and check if the issue comes. 

    Thanks

    Hi RamPrasad

    I have removed the invalid free call from the usecase which is I think creating this issue. 

    The issue has been resolved. Thank you for the support.

    Regards
