The SPI starts and the dataflash is probed but fails with error 255. I tried on another board very similar to at91rm9200ek but with 4 dataflashs (chip select 0 to 3). The flashs 1 2 3 are well detected but the 0 fails also with the same error code. Debug traces tells all transfers seems to be OK. The board with 4 dataflashs works well with a 2.6.17 + patch at91. I don't find any answers to my problem. Could you help me ? Thanks Bruno
