hi Hinko, > Has anybody done something on the SPI flash memory devices already? Yes, there is a driver for Atmel's DataFlash. The driver is included in the 2.4 ARM-Linux kernels (www.arm.linux.org.uk) and the 2.6 patches for the AT91RM9200 processor (http://maxim.org.za/AT91RM9200/2.6/). Regards, Andrew Victor
