Hi, here's a small patch to make initrd working on ARM in u-boot-v2.

I use it to boot over the network like this: tftp /tftpboot/kernel.uImage kernel tftp /tftpboot/rootfs.uImage rootfs bootm -r rootfs kernel

I create the rootfs image like this: mkimage -A arm -O linux -T ramdisk -C none -a 0xA0800000 -n rootfs \ -d rootfs.cpio.gz rootfs.uImage (this is for imx27)

regards,

Eric
