There is no EMIF driver. > send/recv data to the uarts which are expanded by FPGA ,how can i do it? The dm9000 driver on dm365 is on EMIF.

First you configure the address you want to access in one registers, then you read/write the value in another. Again, take a look at the dm9000. It will probably give you some ideas what you need to do to get UART working on EMIF.
