M3VPSS generate no callback during long-run test

Seung Youl Lee1

We are using IPNCRDK 3.0.0 for DM814x custom board. Memory size is 512Mega Bytes.

After several hours long-run test, there is no callback from M3VPSS for new video data.

LCD screen is black screen or stop updating the screen.

When power-up, LCD screen displays the new video data normally.

But, after several hours long-run test, LCD screen stops.

Our usecase links include dual camera, encode/decode, IPCBITS IN/OUT, IPCFRAMES IN/OUT and display

links.

We don't know the root cause of no callback from M3VPSS for new video data.
