Hi,
rootfs loaded with u-boot through ftp and written to nand is mounted by
linux but kernel panics with No init found message. The same rootfs image
uploaded via suprvivi (viq NOR) WORKS just fine even booted when flash
switch is in NAND position.
I have tried many images including root_qtopia-128M.img with exactly the
same effect. Could anyone kindly help me? I confess I am stuck.
I have copied bootargs from supervivi parameters.
bootargs=noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0
here is console log

Kernel panic - not syncing: No init found. Try passing init= option to

It is weird because kernel is loaded via u-boot works, only rootfs does not
I load rootfs with following commands
MINI2440 # nand erase rootfs
