Downloading Image

[Aman]

Hi

I have build a linux image for IBM PPC 440 using the
src-linuxppc_2_4_devel.tar.bz2 [Powerpc Kernel Source] taken from the
website http://www.ppckernel.org/tree.php?id=5. Now I want to download the
image to the IBM PPC 440 evalkit for which I used elf2ppceval utilility by
Grant Erickson.  I copied the script and named as mkevimg.shar. When I
executed the command  "unshar mkevimg.shar ". I got the following error

[root@hardhat aman]# unshar mkevimg.shar
/home/aman/mkevimg.shar:
'h: line 22: syntax error near unexpected token `do
'h: line 22: `do
Broken pipe


Can anyone help me in solving this issue or please suggest the way of
downloading a the 440 image to the IBM PPC 440 evalkit. Also can you suggest
me the cross-compiler for PPC 440.

Thanking you in advance.

Regards
Aman

This step is unnecessary.  The kernel build process generates a
'zImage.ebony' which is directly bootable on the IBM 440GP reference
board.

The ppc4xx toolchain from the free ELDK is what you are looking for.

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.

Aman

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.

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.

Jin Cheng

ELDK Compiler

[Aman]

Hi Matt

I  have downloaded ELDK compiler for PPC 440 evalkit. In the ELDK html file
, it says the the predefined compiler flag as "mcpu=403". Will this ELDK
compiler work very well with PPC 440 processor?. Or are there any other
compilers which works well with PPC 440 processor.

Thanking you in advance

Regards
Aman

Nobody has provided PPC440-specific support for binutils.  Right now,
everybody is using mcpu=[403|405] since they define an identical
set of instructions. The -mbooke support in current binutils will
not work on 440 since it is e500 specific.

The ELDK toolchain works fine.

This is not exactly true, the -mbooke option does NOT produce an e500
specific set of instructions that the assembler knows about but as
close to a generic booke set.  Unfortunately, Book-E leaves remove for
a few instructions to have implementation specific operands (for
example tlbwe/tlbre).  The e500 & 440 differ in the number of operands
these instructions require (e500 - 0, 440 - 3).  The currently binutils
treats these instructions as having no operands.

I am not aware of any other cases in which the current binutils would
not work for 440 code (possibly use of simplified mtspr/mfspr
instructions would not work with the -mbooke flag).
