Sequoia 440EPx patches not working

Sequoia 440EPx patches not working

[Jerone Young]

Using the Sequoia (AMCC 440EPx) patches recently submitted to the list I
am unable to boot to fully boot a uImage built with these patches under
Uboot. It appears to hang in very early boot.


Here is the output:

I'm guessing this is an old version of u-boot, that's not device tree
aware.  That would need a cuImage, not a uImage, and IIRC the posted
patches didn't yet have cuboot support for Sequoia.

The patches do have cuImage support.
I have a Sequoia board with uBoot 1.1.6 and it boots cuImage fine.

This seems to be a wrong image..

Are you using "make zImage" ?

The proper uImage after that command would be smth like cuImage* then...

Speaking of those patches, are you planning on rebasing them against
the latest 4xx series I sent out soon?  That should have some cleanups
that make adding sequoia support a bit easier.

Nope definitely using a uImage. I'll try a fresh source and try again ..
I did base it on kernel.org git tree so I'll try instead with 2.6.23-rc2
and see what happens.

Re: Sequoia 440EPx patches not working

[Jerone Young]

So did a rebase on kernel.org 2.6.23-rc2 patch (as opposed the latest
git). I am using Uboot version  1.2.0-gc0c292b2. This is the version
that came with the board. It still appears to hang during early boot on
my Sequoia.

Trying the cuImage.sequoia.bin.gz just result in Uboot giving "Bad Magic
Number" when trying to boot it. This is also the same for using
cuImage.sequoia.elf. 

So when I use the uImage file it will load but just hang after it's
loaded. I'm building it using "make uImage CROSS_COMPILE=<cross prefix>
ARCH=powerpc" on an x86 box.

I'll see what else I could possibly be doing wrong (maybe something
happened to the patch when I grabbed it off of gmane and the web filters
did something to it, I did have to fix a problem where in the
sequoia.dts file the web filter replace "@" with " at ". This was simple
enough to fix. Maybe something else when wrong. I'll see what else I can
look at.

Please, apply clean patches (not filtered by web filters) and
try make ARCH=powerpc CROSS_COMPILE=<cross_prefix> zImage
The image should be at arch/powerpc/boot/cuImage.sequoia

Re: Sequoia 440EPx patches not working

[Jerone Young]

I got it to load now cuImage.sequoia and loading at address 0x200000. I
had been trying to load at 0x400000...apparently this was not good. So
moving to 0x300000 it loads but stops after setting up the device tree.
So the image was clobbering something but now is not at 0x200000.
Thanks for the help.
