       when use pCaptureInstPrm->vipInstId    = SYSTEM_CAPTURE_INST_VIP1_PORTA;  everything is going right but when i modify pCaptureInstPrm->vipInstId    to  SYSTEM_CAPTURE_INST_VIP0_PORTA; the system will halt (no react and no message print) just after   VpsHal_vpdmaPostList in  file ti/psp/vps/drivers/capture/src/vpsdrv_captureLm.c

    Fang,

    Looks from the log is that Capture FIFO overflow has occurred. Are you using YUV420 formats for capture? Can you try to change it to RGB or YUV422 and try? I'm not saying this is the solution, but this might give a better picture on what exactly could be the issue.
