1  Hardware and U-Boot firmware / U-Boot stuff / Re: Compiling u-Boot-2012.10 for Guruplug Server Plus Target on: December 28, 2012, 06:35:45 PM

Thanks. I'm downloading the ELDK.

I had been downloading a couple of pre-built u-boot from the web to see if I could get these to run. In particular, one I was trying was  http://people.debian.org/~tbm/u-boot/2012.04.01-2/guruplug/u-boot.kwb
My current u-boot version is U-Boot 2010.03-01161-gd91b0a9 (Apr 22 2010 - 03:24:41)

My observation was only a very small percentage of them were working when I was loading them into RAM.

I took the plunge anyway (I have JTAG) and upgraded to the 2012.04.01-2 version above and it worked fine once flashed. I notice I can now load the same u-boot into RAM and chain load it. So I supect there is also a couple of issues with some older u-boot's chain loading.

It doesn't fix my u-boot binary, so I'll give it a compile with ELDK later and see what eventuates.

Has anyone cross-compiled the latest u-Boot 2012.10 for the Marvell Kirkwood based Guruplug Server Plus?

I can successfully compile an image, but I can't get it to load. Nothing is displayed on the console when I execute it.

I'm using gcc version 4.6.1 (Sourcery CodeBench Lite 2011.09-70)

wget ftp://ftp.denx.de/pub/u-boot/u-boot-2012.10.tar.bz2
tar -xjf u-boot-2012.10.tar.bz2
cd u-boot-2012.10

export CROSS_COMPILE=arm-none-linux-gnueabi-
make distclean
make guruplug_config
make u-boot.kwb

It completes with:

Preparing kirkwood boot image to boot from nand
Nand ECC mode = default
Nand page size = 0x800
Image Type:   Kirkwood Boot from NAND Flash Image
Data Size:    237780 Bytes = 232.21 kB = 0.23 MB
Load Address: 00600000
Entry Point:  00600000

I then try to load the new uBoot image via TFTP to test it :

setenv ipaddr
setenv serverip
tftp 0x800000 u-boot.kwb
go 0x800200

I use an offset of 0x200 to jump over the Kirkwood Image Header. (I've also tried loading the .bin with no offset)

I've also tried u-boot-2011.12 but with the same result.

Any clues as to what I'm doing wrong? Or should I be using a different compiler?

So there seem to be a heat/power consumption problem...grml

I think your are on the right track.

I too have seen this problem with my unit rebooting with Gigabit Ethernet. It crashed at different stages, so it looked like a power supply issue. I have opened my unit in preparation to replace the power supply, but find it works fine on the bench when it is in pieces - i.e. there is good separation between the original power supply and the aluminium heatsink attached to the 88E1121R PHY, Processor, RAM etc.

I can load the original power supply (external bus powered harddisks etc) without effecting it, so the power supply seems fine.

Just gotta work out if its the power supply buckling under the heat, or the 88E1121R PHY, Processor etc
