Dear Friends,

I have AT91SAM9M10G45-EKES Kit and using kernel version 2.6.30. I am trying to build polling based SPI driver that communicates with the Dataflash provided with the kit.

Please find the attached code with the post http://pastebin.com/qK4yXGYm . I am not able to get the Clock signal on the oscilloscope when I load the own build driver. I also tried putting the debug statments on the atmel_spi.c driver with the source and found the values of CSR0 and MR registers. I used those values on my driver based on polling.

Can anyone pointout the missing link into the driver? Any suggestions are warmly welcome?

Have a Good Day,
Thank you,
Ankur.
