Hi Dan,
Is there any timing diagram with the SGDMA? I want to control some of the signals directly in the FPGA.

Hi Dan,
I'm confused about this, does the Go signal go to "0" after each transfer such that I have to toggle it ba... Anonymous

Yes, you need to set the go bit so the dispatcher knows that the descriptor is ready to be read.

Hi again,
Just reading through the document. Do I have to set GO to '1' each time I update the descriptor?

Hi Dan,
What's parked write? Is that just writing to one address only?
Is the descriptor like an address line?
