AVNET 440GX board

AVNET 440GX board

[-- Attachment #1: Type: text/plain, Size: 1550 bytes --]

Hi,

I'm trying to boot Linux on  AVNET 440gx eval board but no luck so far.
What I did are that I downloaded a plain 2.6.20 kernel from kernel.org,
configured with 440GX, OCOTEA target (I'm not sure OCOTEA is correct
target),
then loaded the kernel image via tftp  and tried to boot with bootelf
command.
But I had no output message from Linux.

I suspected setting of Linux serial console. So I changed the kernel
parameter to
"ttyS0,19200" which I suppose correct becuase this is the minicom setting.
But still didn't work.

The board comes with u-boot 1.0.2 with some fixes.  I'm checking the u-boot
source code (might be some hint in there) and the serial device
initialization code in Linux.

Has anyone had experiece with Linux on AVNET 440GX board?
Any advise would be appreciated !

I don't know the AVNET 440GX eval board. Is it _identical_ to the IBM/AMCC 
Ocotea? If not you will most likely have no luck with this image. You will 
have to port Linux to this special board.

Hmmmm. That's a strange image name. Normally you should boot the uImage file 
from U-Boot.

And use the "bootm" command to boot the uImage.

No, it's not identical.  We had one of these boards at one point and it
was a pain in the arse.

yeah, sounds like. I was so optimistic that Linux is kind of primary OS for
any ppc board  when I choosed this board :-)

I was just using the elf image, instead of uimage.
'6501A8C0.img' is refereing zImage.img which is Linux elf image.
It looks to me that the bootelf command interprets ELF format corrently.

As you sugested, I also made uImage and used bootm to boot it.
But no luck. Here is the log.

Hi,

I decided to start tracing down the issue. I'm debugging early stage
by adding primitive debug code ( I don't have a fancy cpu debugger,
sign)

foobar:
        .long 0
start_:
        lis   r4, foobar@h
        ori   r4, r4, foobar@l
    li    r8, 0x1111
        stw   r8, 0(r4)

I found that the bootelf command actually jumped to _start(), and then
stoped inside load_kernel()@arch/ppc/boot/simple/misc.c.  Because of
stupid debugging method, just slow progress.

Of course you had no luck, since the Ocotea uImage can't work on a different 
hardware like the AVNET board. Again, you have to port Linux to this platform 
first. And you need to know detailed information for this procedure 
(schematics...).

You shoulkd really read the documentation. bootelf is not the correct
command to boot a Linux kernel image, and the ELF file is not the
correct image to use.

Also, "6501A8C0.img" means you fell back to using the encoded IP
address of yoru target as file name because you failed to provide a
valid image name.

Again, I strongly recommend to read the fine manual.

You waste your efforts. You use the wrong image format (ELF instead of
uImage] and the wrong boot command [bootelf instead of bootm].
