    Are you passing any buffer other than allocated from SR1 to ipcBitsInLink ? If you just get the buffer from ipcBitsInLink and free it back without processing so you still see hang ?

    Can you print the siginfo.It may give some additional info. It looks like invalid memory access but but weirdly doesn't cause page fault.

    kernel/signal.c

    get_signal_to_deliver

    add

     print_fatal_signal(info->si_signo);

    before call to

     do_group_exit(info->si_signo);

    The problem just occur one time. so i can got anymore information now.

      But i find another problem, seems still have bug in dvrrdk4.1.  

      I write a custom demo my self with cap, enc, dis.   type 'e' can exit the demo.  

       I stop the demo, If i wait sevaral seconds, then restart the demo,. do stop,wait, restart several times. everything is ok.

       buf if i restart the demo immediately, 3 or 4 times later, the demo will report exception.

    Share full console logs. Also get the CCS CRASH DUMP file and attach your .xem3 for m3vpss.

    This looks like issue with TVP7002 configuration from M3. As mentioned before do the configuration from A8 and don't configure external video decoder from M3.
