I now updated to kernel 2.6.25 for various reasons. Now, we use the _new_ atmel_spi driver and mtd_dataflash driver (but the problem also exist if I use the legacy one). If I try to mount a jffs2 or cramfs image on dataflash I get the following error: # mount /dev/mtdblock5 /mnt/flash mount: mounting /dev/mtdblock5 on /mnt/flash failed: Block device required Exactly the same line works with the 2.6.21 kernel. Also doing a cat on the normal /dev/mtd* nodes also works. "cat /proc/devices" shows: Block devices: 7 loop 31 mtdblock So I have no idea here. Any hints? Thanks in advance. Best regards, Andre
