Hi,

I'm struggling with the topic for long two days and I want to ask for help.

I have a DNS-320 system with u-boot. I compiled kernel and it works 
well, but I need initramfs. I prepared contents on this system (ARM) (no 
need to cross-compile), then did:

find . -print0 | cpio --null -ov --format=newc | gzip -9 > initramfs
mkimage -A arm -O linux -T ramdisk -C gzip -n "Some name" -d initramfs 
initramfs.kwb

flash_eraseall /dev/mtd2
nandwrite -p /dev/mtd2 ./initramfs.kwb

reboot

Marvell_DNS320>> nand read.e 0xa00000 0x100000 0x200000

NAND read: device 0 offset 0x100000, size 0x200000 load addr ....  =a00000

  2097152 bytes read: OK

Starting kernel ...

And here it hangs.


If I skip passing initramfs system boots properly.
What is wrong?
