Hi,
I am working with AT91SAM9260 based board. On this board, we have connected 64MBit DATA Flash on SPI. We have connected SPI0_MISO (PA0), SPI0_MOSI (PA1), MCCK (PA8) & SPI0_NPCS1 (PC11) to the So, SI, CLK and CS on the data flash.

I DO NOT want to boot the board from the images on this DATA Flash, but just to save user critical parameters onto this memory.

May I know the steps, to make data transfers to this DATA Flash from User application?

Thanks in advance.

Cheers,
Jagan

The simpliest way is enable the DATA FLASH in the kernel build and mount the DATA FLASH as a MTD device.  Then it can be accessed as part of the file system.  Or do not mount it at all just use the MTD utilities to read and write the FLASH.
