We are make board with iMX53, unfortunally initramfs.cpio.gz.uboot from MfgTool is not work on our board and I have to modify it.


$ file initramfs.cpio.gz.uboot

initramfs.cpio.gz.uboot: u-boot legacy uImage, uboot initramfs rootfs, Linux/ARM, RAMDisk Image (gzip), 4144518 bytes, Wed Mar 16 06:24:19 2011, Load Address: 0x00000000, Entry Point: 0x00000000, Header CRC: 0x6548D031, Data CRC: 0xA090FD19

But I can't unpack it...

$ cp initramfs.cpio.gz.uboot initramfs.cpio.gz

`initramfs.cpio.gz.uboot' -> `initramfs.cpio.gz'

$ gunzip initramfs.cpio.gz > initramfs.cpio

gzip: initramfs.cpio.gz: not in gzip format


How can I unpack and modify it?

Thank you and excuse me my bad english.
