Hello!

Im trying to use embedded ramdisk on boot.
The error is:

[4294668.794000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
In make menuconfig I pass to initrdfs directory with my root("/mips/root"),
there are no errors on make. Ramdisk size set to 7777k
([4294668.691000] RAMDISK driver initialized: 2 RAM disks of 7777K size 1024 
blocksize)

populate_rootfs() works fine:


[4294667.502000] init/initramfs.c void __init populate_rootfs(void);
[4294668.313000] checking if image is initramfs... it is
why using initramfs with initrd ?

then on do_mounts in void __init mount_block_root(char *name, int flags)
it tryes to mount initrd with no result. :( As final:


[4294668.794000] Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(1,0)

Any ideas?
maybe try to add in your kernel command option: "rootfstype=ramfs"

Kernel from cvs(yesterday updated).

Which type of fs is initrd? AFAIK gen_init_cpio just generates cpio archive 
with my root. Seems like it unpacked fine but who did mkfs on /dev/ram0?


initrd fs depends on how your initrd image is built.
initramfs fs is ramfs.

cheers,

               Franck
