DMA Transfer

All,

 

I am writing a custom driver for a peripheral built on the opb_ipif interface with DMA built-in to the peripheral.  The peripheral has a read FIFO.  I wish to transfer data from this FIFO to memory for access via a read call on my device.  Any suggestions for reading material? 

 

I thought you would use calls to dma_map_single(...) and dma_ unmap_single(...), but I am having trouble with them.  Am I on the right path?
