TDA4VM: TDA4VM: Rtos 0806: Does C6x_2 affect the video channel UDMA

Part Number: TDA4VM

Tool/software:

Hi,



My solution uses UDMA-DRU, copies the camera image and processes it before displaying it on DSS.
DSPC6x_2 uses Audio to play sound, and also uses PDMA
Now when the Audio function is turned on, the screen flickers, and when the Audio is turned off, the screen does not flicker.
Both screens flicker, it seems that the DMA copy is not completed and returns.

How to deal with it?
thanks
Dong zhang
