Hi,
I'm trying to understand how the dma linking/chaining works on the am335x . What I'm trying to do is this:
On a previous system using a plx 9056 dma controller, I set up a parameter list in kernel memory which contained essentially the scatter gathered physical memory list. Each element in the parameter list had a physical address, length and a link to the next element containing next address, length and so on.. the last element in the list had the end of chain link bit set. I then pointed the chip to the start address of the parameter list and kicked it off - all works well..
I'm now trying to do the same thing with the edma driver - is it possible, any help or suggestions would be appreciated.
Thanks,
