I am using ELDK-2.0 to create a bootable kernel image for PPC8xx. I have
PPCBoot on my target and I want to download the kernel from the host to

the

target using TFTP boot. I have verified that I can transfer the image via
TFTP boot. I am creating the initrd image using the following sequence of
commands.

1. make config
2. make dep
3. make clean
4. make zImage.initrd
5. Compress the "zvmlinux.initrd" executable using "gzip"
6. Execute mkimage command to prepare it for "ppcboot"

After the image is downloaded the kernel image is uncompressed without any
errors. But then I get the messsage "No initrd" and the system no longer
responds. Can one of you please point to where I may be going wrong?

For PPCBoot you normally build a pImage with:

 make pImage

and building a RAMDisk image is done differently as well. Have a
look to chapter 5 and 6 of the DENX PPCBoot and Linux Guide at http://www.denx.de/doc/TQM8xxL/.
The ELDK 2.0 comes already with
a working pRamdisk image provided by the RPM package SELF.It can
be found in "ppc_8xx/images". You need the SRPM if you want to
modify it. Also check ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/.

Hope it helps,

Wolfgang.
