Brett,

You are right. The first step(writing 0xffff to DW0)will reset the DMA and last

step(writing to DW3) will start the DMA. But i am seeing some issue with write_dma read address to end point memory in RTL. The address goes beyond the length specified in descriptor. It looks ok with read DMA. Has anybody observed same and tested at higher level ?.
