TMDSEVM572X: EDMA tutorial

Richard Breyer1

Part Number: TMDSEVM572X
Other Parts Discussed in Thread: AM5728

I am reading the edma and ipc user guides and AM5728 tech reference all together trying to figure out the right way to initiate DMA on the PRU and DSP and notify (interrupt ?) the DSP and ARM when done. Do you know of a tutorial where these elements are pulled together in a comprehensible whole to shorten my research phase?

Hi Richard
Can you elaborate further on your use-case
>>right way to initiate DMA on the PRU and DSP and notify (interrupt ?)

Additionally can you tell us what OS you are using , is it Linux on ARM side and RTOS on DSP side?

Mukul

Hi Richard
I was sieving through list of open/not resolved threads, this popped up. We did not hear back from you, so I am marking this as TI Thinks Resolved.
Please feel free to open another thread or reply back if you have not been able to make progress on this.

Regards
Mukul
