Booting using initramfs instead of uramdisk

Question

I am working on Zynq Microzed board. It is booting perfectly with uramdisk.image.gz but I trying to boot it with initramfs.cpio.

In this regard I have made following changes in header files of u-boot:

zynq_common.h and zynq_common.h.save changes are as follows

"ramdisk_image=uramdisk.image.gz\0"

to

"ramdisk_image=initramfs.cpio\0"

in both the header files

I am getting following log messages

It is still looking for uramdisk.image.gz and giving an error

Wrong Ramdisk Image Format

Ramdisk image is corrupt or invalid

I am unable sought out where I am getting wrong and how to resolve it.

Solution

I think you should convert it to u-boot file like this and give it a try:

mkimage -n 'Ramdisk Image'  -A arm -O linux -T ramdisk -C gzip -d initramfs.cpio.gz initramfs.uImage

This might be a valid format for u-boot.
