Hi everyone

I want to write a driver in uclinux , which use memory DMA to transfer data, However , after I set the DMA controller, the driver can not work normally.   Could you give me some documents about BF533 DMA, especially about memory DMA in the uclinux

Thanks

Hong

searching our wiki with "dma" as keyword you will find many docs: http://docs.blackfin.uclinux.org/doku.php?do=search&id=dma

Also you can refer to arch/blackfin/kernel/bfin_dma_5xx.c.
