LinuxQuestions.org - Kernel image corrupted : Wrong Image Format for bootm command ERROR: can't get kernel

Whenever I try to reboot my linux system I get the error message

Code:

Wrong Image Format for bootm command 

ERROR: can't get kernel

and fall back to the uboot prompt. I suspect the filesystem overwrote my kernel's partition coz everything works fine if I mount the root filesystem as read-only .

My uboot environment :

Code:

U-Boot> printenv

bootdelay=3

baudrate=115200

boot_addr=0x21500000

bootcmd=run boot

ker=nand read 21500000 200000 160000

boot=run ker; bootm 21500000

bootargs=mem=64M console=ttySAC0,115200 noinitrd root=/dev/mtdblock1 ro rootfstype=jffs2

My rcS script :

Code:

#!/bin/sh

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin

runlevel=S

prevlevel=N

umask 022

export PATH runlevel prelevel



# mount proc

mount proc /proc -t proc

#remount filesystem as read-write

mount /dev/root / -o remount,rw



# insmod sdio.ko

if [ -f /usr/modules/unifi_sdio.ko ]; then

        insmod /usr/modules/unifi_sdio.ko

else

        echo -e "unifi_sdio.ko not exits !!!!"

fi

I would appreciate your help.
