Hi all! I am trying to boot my board with initramfs file system. After loading the kernel image and initramfs onto uboot, executing bootm command gave me errors of "bad magic number". Then I tried to append header information using mkimage, here's what I executed:

/tools/mkimage -A ppc -O linux -T filesystem -C gzip -n 'Initramfs root file' -d /exports/myinitramfs.cpio.gz myramfs Image Name: Initramfs root file Created: Tue Sep 16 21:28:41 2008 Image Type: PowerPC Linux Filesystem Image (gzip compressed) Data Size: 51685255 Bytes = 50473.88 kB = 49.29 MB Load Address: 0x00000000 Entry Point: 0x00000000

When I try to boot this image, I am getting "No Linux PPC Ramdisk Image"

## Loading RAMDisk Image at 00900000 ... Image Name: Initramfs root file Image Type: PowerPC Linux Unknown Image (gzip compressed) Data Size: 51685255 Bytes = 49.3 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK No Linux PPC Ramdisk Image (u-boot restarts after this)

1. Where am I going wrong. Can I not boot using Initramfs, or should I create Ramdisk image only for booting the board. 2. If I need to create ramdisk using genext2fs is there any size restriction, that the file size should be less than 8 MB?

Please let me know.

Thanks, joy
