I had booted up Linux with nfs root, and write a JFFS2 image to /dev/mtd1.
Here is my cmdline for Kernel:
go 0x80305018 root=/dev/nfs rw nfsroot=172.19.26.145:/nfs/rootfs
After writing the JFFS2 image to /dev/mtd1, I can mount /dev/mtdblcok1 to
mount -t jffs2 /dev/mtdblock1 /mnt
Next, I hope to boot up Linux with JFFS2 root, and try to give this cmdline
go 0x80305018 rootfstype=jffs2
and the Kernel would complain me about no root:
VFS: Unable to mount root fs via NFS, trying floppy.
Kernel panic: VFS: Unable to mount root fs on unknown-block(2,0)
I traced the code and found that when passing "/dev/mtdblock1" to
name_to_dev_t() in do_mounts.c, it would return 0 at every try_name(),
which will fail at open() with the path "/sys/block/%s/dev".
What's the problem? Could anyone tell me?
Thanks and regards,
