Hi,

I am wondering whether can use the OpenBIOS coming with the 440GP Ebony board
to load the linux kernel or there is a ppcboot for Ebony which can do that? Thanks.

Sincerely,

Jin

Hi Jin

The eval kit for IBM PPC 440 has OpenBios as the rom monitor code. I compiled the PPC kernel with Mvista 405 compiler. As Matt Porter suggested, I download the zImage.ebony using the TFTP. The Image is downloaded to 440 board, however finally it says PPC unknown. I trying some sample application on the ebony board now.

Regards
Aman

Downloading Linux image using Riscwatch

Hi All

I am using PPC 440GP processor on custom board. This board doesnt not have Ethernet support and there is no rom monitor code in the board. Is it possible to download the Linux image to the board using JTAG . If so what type of image should I build.

Thanking you in advance.

Aman

The arch/ppc/boot/images/zvmlinux.* file is a standard ELF image. Your tool should either allow you to load that format directly or should accept a format to which it can be easily converted.

Hi,

I used ELDK ppc_4xx toolchain to compile a kernel from the same source as Aman. I followed the arch/ppc/configs/ebony_defconfig and get a kernel.

Then I used the OpenBIOS to load that kernel. it is loaded fine, but the kernel always
times out on "Sending BOOTP request..."

I used other machine to test my nfs server, it works fine.

Following is the screen out, Could you give me advice on the problem? Thanks.

Regards,

Jin Cheng

zImage.ebony boots from OpenBIOS. Check the ppcboot-users list for information on ppcboot for the Ebony board. Somebody has contributed some code for a custom 440GP board and several people seemed to be working on an Ebony port.

We have Ebony boards booting via ethernet/TFTP using PPCBoot, and I believe our code has been checked into the PPCBoot CVS.

Best,
Roland
