Dear Ankit,

when you need help with die device driver, write the mailing list at rocketboards.org and look into the archive. I am also at a similar projekt, when you want to use "Master" Transfers (DMA-330 initializes transfer) there is no example driver. For "Slave" Transfers (Peripheral has to request transfers) you will find an example in the "linux-socfpga" repository. "fpga-dma.c" under "linux-socfpga\arch\arm\mach-socfpga" . just some hints. I am also not finished with my driver.

Kr,

Florian
