Hello All,
I am facing some issue when I flash kernel from busybox and try to boot
from redboot console.
The same kernel work correctly when I write it using "fis write"
command. Below are the steps:
1.load kernel + ramdisk from tftp by using below commands :
> load -r -b 0x100000 zImage -h 10.100.4.78
2.Boot with above kernel using 'exec' command
3.Write zImage from busybox console by using below commands:
> dd if=zImage of=/dev/block/mtdblock0 bs=128k
4. reboot busybox
5. Stop on redboot
6. load kernel with the help of following command :
> fis load nx1
> exec
Redboot stuck while uncompressing linux.

RedBoot> fis load qnx1
