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
Marvell_DNS320>> nand read.e 0xf00000 0x600000 0x500000

Marvell_DNS320>> bootm 0xa00000 0xf00000

And here it hangs.
If I skip passing initramfs system boots properly.
What is wrong?
