Also determines which channel to use. 2. register an interrupt handler for the DMA interrupt line. 3. fire the DMA. where can i find these APIs, or i m missing something? thanks in advance for ur help -- View this message in context: http://www.nabble.com/using-dma-engine-on-MPC8555-processor-tp21683674p21683674.html Sent from the linuxppc-dev mailing list archive at Nabble.com.
