DMA Linked list implementation example required( multiple TCS in one DMA channel and Dma in circular linked list form for TC3xx )

shailijha · ‎Nov 24, 2021

I want to implement circular linked list for a DMA channel( i.e multiple TCS inside a DMA channel).

I have different source and destination corresponding to each TCS which I need to pass through TCS structure during runtime with an api (eg ChUpdate(x,y,z)).

I need help with passing values in that TCS structure as well as how to pass next TCS address and through which DMA API should I implement the linked list feature if it exists in EB plugin driver code?

Hi shailijha. Have you looked at the Application Note AP32467_DMA_LinkedListModes_TC3xx_v1.0.0.pdf? That has some good examples.

Another source for examples is AURIX Development Studio. It has a few linked list projects in File / Import:
