Try creating a symlink from /init to /bin/busybox, worked for me...

Subject: [gentoo-embedded] TinyGentoo Boot Issue
 
I have been trying, in vain, for several days to get TinyGentoo to
boot from a USB drive. I have followed all of the instructions (twice)
and cannot get past a kernel panic issue that I am having.

Here is the issue...Grub comes up just like it should, the initramfs
gets into memory and the boot starts. There are several checks that
take place then the kernel load is attempted. This is where everything
falls apart...the kernel panics.

I get something to the affect of...

VFS: Cannot open root device "<NULL>" or unknown-block (0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block
(0,0)

I have searched around and here is what I have tried...
* Add root (0,0) line to grub conf
* Add root= parameter to the kernel line in grub conf (both /dev/sda1
and /dev/ram0)
* Add a mount delay to the kernel line in grub conf
* Rebuilt the kernel according to the instructions (for good measure)

Any help would be appreciated.

I tried your suggestion and now I get the same message with a
different block set (3,2) instead of (0,0).

Could it be something in the kernel that I missed?

Hi Chad,

This may not be the same but a similar thing happened to me when trying to
mount a jffs2 root partition while not having jffs2 compiled into the
kernel, the kernel can't mount the root partition so bails out with a 'VFS:
Cannot open root device' error.

What partition are you using? vfat? Was the partition created/formatted
correctly? Did you include vfat support in the kernel? Did you build support
as a module? Drop me an email if you don't know how to check for the option
in the kernel .config (CONFIG_VFAT_FS in the case of vfat) or when you 'make
menuconfig'.

HTH,

Tim

The boot partition is an ext2 there is a secondary partition that is a vfat.

Yes.

Yes and Yes.

I started with a clean kernel (yet again) and the boot still hangs at
the same spot. I am really at a loss of things to try.

[gentoo-embedded] TinyGentoo Boot Issue

[Chad Files]

I have been trying, in vain, for several days to get TinyGentoo to
boot from a USB drive. I have followed all of the instructions (twice)
and cannot get past a kernel panic issue that I am having.

Here is the issue...Grub comes up just like it should, the initramfs
gets into memory and the boot starts. There are several checks that
take place then the kernel load is attempted. This is where everything
falls apart...the kernel panics.

I get something to the affect of...

VFS: Cannot open root device "<NULL>" or unknown-block (0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block (0,0)

I have searched around and here is what I have tried...
* Add root (0,0) line to grub conf
* Add root= parameter to the kernel line in grub conf (both /dev/sda1
and /dev/ram0)
* Add a mount delay to the kernel line in grub conf
