Hi Gary, You are correct, I 'm in the process of writing a device driver for the NAND flash on my board. Only the progress is not so fast. Currently I'm reading some documents about NAND flash devices, the Open NAND Flash Interface (ONFI) and the peripherals inside the at91sam9260 which support the NAND flash. So I haven't writen any code yet. My spare time is also limited. Comming week I will have no time at all to work on this driver. I cannot say when I will finish, so you better not wait for me.
