Hi Hinko,
I had a similar problem. If you make sure that your Flash is programmed similar to the following order then it should work with the setup you describe:
Image1 Addr1 u-boot <-- mounted as /dev/mtdblock0 Image2 Addr2 kernel <-- mounted as /dev/mtdblock1 Image3 Addr3 jffs2 <-- mounted as /dev/mtdblock2
Hope this helps, Alan.

Hi,
(I apologize if the list recieves this(similar) mail twice)
I have jffs2 fs image in flash and would like to mount it when linux asks for root fs.Linux gives out: ... Root-NFS: No NFS server available, giving up. VFS: Unable to mount root fs via NFS, trying floppy. Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) <0>Rebooting in 5 seconds..ÿ
and command line is: Kernel command line: root=/dev/mtdblock2 rootfstype=jffs2 rw console=ttyS0,115200 mem=64M panic=5
Image is located at 0x2c0000 and u-boot can see it, too: Ub00t> ls Scanning JFFS2 FS: ...... done. drwxr-xr-x 0 Mon Feb 21 11:39:54 2005 bin drwxr-xr-x 0 Mon Feb 21 17:48:03 2005 dev drwxr-xr-x 0 Fri Feb 18 14:00:50 2005 etc drwxr-xr-x 0 Wed Feb 23 16:38:26 2005 lib lrwxrwxrwx 11 Tue Feb 22 07:58:53 2005 linuxrc -> bin/busybox drwxr-xr-x 0 Wed Dec 29 11:01:22 2004 mnt drwxr-xr-x 0 Tue Jul 20 10:38:27 2004 proc drwxr-xr-x 0 Thu Feb 17 21:58:50 2005 sbin drwxr-xr-x 0 Wed Feb 23 17:40:11 2005 staging drwxr-xr-x 0 Wed Feb 23 23:27:06 2005 tmp drwxr-xr-x 0 Wed Feb 23 16:40:41 2005 usr drwxr-xr-x 0 Tue Jul 20 10:38:41 2004 var
But how do I supply this info to u-boot when booting linux? Is 'fsload' the right way to go? But I would still like to have kernel
separated from fs image...
Using kernel 2.6.9 here.
regards, hk
