When running the mcfw demo ,i select  the 6: VCAP + VDIS  - NO Encode or Decode,after almost 30 minutes the HDMI  was no output video.When i restart the demo,the will halt at

 Enter Choice: 6

 0: SYSTEM: System Common Init in progress !!!
 0: SYSTEM: IPC init in progress !!!
12: SYSTEM: Opening MsgQ Heap [IPC_MSGQ_MSG_HEAP] ... <-------------------------------------halt

Is there any way to debug the vpss(M3) when runnung demo? If  the TVP5158 clock(108MHZ) was unstability,the output will be  interrupt?

    Hello,

    Sorry for the late response. You can use CCS to connect to the target and run the program to have some debug visibility. CCS has debug visibility to the M3. But you may want to also post in the 816x forums for specific advice related to the demo and your target. They would have the expertise to give you ideas on where to look during debug.

    Thanks

    Thank you. But when i use ccs5.1 to debug M3,it can't mapping resource code.And it's not easy to debug vpssm3 in this way,because the BIOS program need to communtication  with linux program in MSGQ,when debug the A8 core and vpssm3 in the same time,the communtication with 2 cores is not very synchro.
