Hi,
I have the basic MTD and Yaffs driver working: I can mount mtd yaffs
partitions, read write data to the partitions OK. But when I try to use
a yaffs partition as the rootfs I get a:
Kernel panic: No init found.
The way I am "uploading" the data is that I first boot using an initrd
image. Then I mount the yaffs partition and copy all the contents of the
root fs to the yaffs partition (create the dev nodes, symlinks, etc..).
Then I reboot and instruct the kernel to use yaffs as the root
partition.
I've also tried passing the init=/sbin/init , init=/bin/sh, ...
Any suggestions on what could be the issue?
