Can you explain what it means with EDMA3.maxRequests?

What will change if modify from "EDMA3.maxRequests=128" to "EDMA3.maxRequests=512"?

Thanks and regards,

Hayden

Thanks Veeranna.

One more question about edma3 maxRequests.

Is the value of maxRequests related with the FIFO count inside of the EDMA operation?

Is it possible that the FIFO is full while running?

In that case of FIFO full occurring, will it be helpful to increase the maxRequests value (ex. from 128 to 512)?

Thanks and regards,

Hayden
