Hi
I tried pRamdisk for ppc_4xxFP and ppc_4xx. I am not sure of the difference between ppc_4xxFP and ppc_4xx. But just a heads up. With ppc_4xxFP, I get the same results as for the
Simple Ramdisk-Image I used before i.e. after the boot process I get no prompt on the screen. VFS: Mounted root (ext2 filesystem).
With ppc_4xx, I get these messages
Freeing unused kernel memory: 52k init serial console detected. Disabling virtual terminals.

I also have a question concerning Linux debugging with abatron. I can set an instruction breakpoint (e.g at start_here in the kernel) when I use a zImage.elf image but the same breakpoint doesnt work when I use u-boot to boot vmlinux.PPCBoot image.
Thanks, Shamile

Yeah that was the problem. So now it boots all the way.
I
am not sure what this Simple Ramdisk-Image is composed
of
as I do not get to a promt. I get nothing on the
terminal.
This old MPC8xx-only ramdisk image is really causing more harm than being helpful. I removed it from the FTP server now.
Please use instead an image that was build for a 4xx system.
You can find SELF based images in ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/images/
Best regards,
