    I got an error like this

    SYSTEM: IPC: [DSP1] Notify recvfrom failed (Link has been severed, 67) !!!
    [HOST] [HOST ] 148.767004 s: SYSTEM: IPC: [DSP1] Notify recvfrom failed (Link has been severed, 67) !!!
    [HOST] [HOST ] 148.767004 s: SYSTEM: IPC: [DSP1] Notify recvfrom failed (Link has been severed, 67) !!!

    [HOST] [HOST ] 148.767065 s: SYSTEM: IPC: [DSP1] Notify recvfrom failed (Link has been severed, 67) !!!

    The SurroundView application is running in DSP core. In the algorithm an xml file has to read from the SD card.

    Everything was working fine before having this xml read in DSP core. Got this error when tried to read xml file from SD card for the code running in DSP core.

    Below one is the usecase:

    UseCase: chains_nullSrc_Display

    NullSource (A15) -> Decode -> VPE -> Sync (A15) -> Alg_SurroundView3d (DSP1) -> SgxCarDisplay (A15)

    SgxCarDisplay -> Display_M4 (IPU1_0)

    In "Alg_SurroundView3d" xml read is to be done.

    SDK version 03.07.00.00
