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.
