Hi! I have a problem with booting linux on my mini2440 board. It's unable to mount rootfs: --------------------------------------------------------------------- VFS: Cannot open root device "mtdblock3" or unknown-block(31,3) Please append a correct "root=" boot option; here are the available partitions: 1f00 256 mtdblock0 (driver?) 1f01 128 mtdblock1 (driver?) 1f02 5120 mtdblock2 (driver?) 1f03 256640 mtdblock3 (driver?) 1f04 262144 mtdblock4 (driver?)

Make yaffs2 image from http://www.friendlyarm.net/downloads I'm using the default mini2440_defconfig, but added the yaffs2 support at Filesystems section. I flashed the device via serial terminal and the s3c2410_boot_usb tool. I created the rootfs image with mkyaffsimage /my/rootfs/root/dir /path/to/image/file command. 1) Using NOR state of switch 2) x for formatting 3) v to downloading supervivi-128M image 4) k to download zImage 5) y to download rootfs image (yaffs2) 6) s and s to update linux command line parameters to: noinitrd root=/dev/mtdblock3 rootfstype=yaffs2 console=ttySAC0,115200 7) b to boot from flash Could anybody help to me? What do I wrong? Thanks! Wakoond
