Hi, In my application I am using PDMA ch1 for audio buffer updates. LCD display seems to be using PDMA as well. NVT_Draw1 function defined in fsa506.c there is some doc on how it works. It completely resets PDMA0, thus interrupting any other channels. NVT_Draw1 is called each frame of the application. Bu the problems with PDMA interruption trace earlier all the way to APPW_Init() function. After it is called, my PDMA ch 1 stops working. My question is whether there is any specific ways to handle…
