Hi TI,

I am working on a DM8148 Custom Board ,i am using latest EZSDK 5_05_02 . We have integrated drivers for custom video decoders in the hdvpss source in the EZSDK 5_05_01_04 . Now i am trying to migrate to hdvpss source in the latest EZSDK 5_05_02 . I have done the integration of the drivers for the video decoders in the latest hdvpss source . Using the latest hdvpss fimware when i ran the OMX app ,I see my app hangs at capture control ( TVP ) state execute and the logdump shows the below error .

    Hello,

    It seems to me is that VPSS M3 core crashed.

    Could you check for errors, when the VPSS module is loading at the beginning ?

    Best Regards,

    Margarita

    Hi Margarita,

    Thanks for the reply . I don't see any errors when VPSS and the hdvpss,hdvicp firmwares are loaded . Now I am getting this type of error logs in the CCS console ,

    I can step through the code in CCS , I see the crash is happening at retVal = channel->drv->drvOps->control(channel->drvHandle,cmd,cmdArgs,cmdStatusArgs);when the IOCTL_VPS_VIDEO_DECODER_GET_VIDEO_STATUS is called from OMX layer .

    But sometimes this error won't come I can see the app executing fine without any problems . Can you help me out in interpreting the above stack dump ,so that i can find out what's responsible for the error .

    Thanks,

    N Sivaramkrishna .

    Hi ,

    One thing i forgot to tell you , I have just updated the HDVPSS and HDVICP fimwares to EZSDK 5_05_02 ,but the linux kernel ,u-boot are from the older EZSDK 5_05_01_04 .

    Even my OMX app is compiled against the older component sources (ezsdk 5_05_01) . Is this the safe way to do ? Can we use the new firmware and older linux kernel ,u-boot,filesystem from EZSDK 5_05_01 .

    I am also seeing the below warning when the HDVPSS firmware is getting loaded .

    VPSS_FVID2: M3 firmware version 0x1000145 is newer,driver may not work properly.

    Can you please clarify the above usage ? Do you think this may be reason for the M3 throwing exceptions ?

    Thanks,

    N Sivaramkrishna .
