beagle-xm Rev C MLO, u-boot

Hi,

Can someone please point me to a repository for u-boot and x-loader
(MLO) which is supposed to work with a beagle-xm Rev. C.

I mean I would like to have networking up and running in u-boot
(booting kernel over tftp and getting rootfs over nfs) and also be
able to load a kernel+rootfs from an SD card.

I'm using a 3.1 mainline kernel.

Maybe "known to work" tags would also be useful.

So far I tried various Angstrom/Narcissus images (and the MLO,u-boot
in there),
http://www.angstrom-distribution.org/demo/beagleboard/MLO
http://www.angstrom-distribution.org/demo/beagleboard/u-boot.bin

In many cases that's all I see:

Texas Instruments X-Loader 1.5.1 (Oct 24 2011 - 23:55:51)
Beagle xM
Reading boot sector
Loading u-boot.bin from mmc

(stuck here)

When I use git://github.com/koenkooi/u-boot.git I get:

Why not check the angstrom buildsystem?

Why not check the angstrom buildsystem?

Because the MLO/u-boot I get from various narcissus images produces
this:

Texas Instruments X-Loader 1.5.1 (Oct 24 2011 - 23:55:51)
Beagle xM
Reading boot sector
Loading u-boot.bin from mmc

I tried the following:

SRC_URI = "git://www.denx.de/git/u-boot.git;protocol=git \
           file://2011.12/0001-beagleboard-mount-rootfs-RO-instead-of-RW-at-boot.patch

          "

# v2011.12 tag

No luck, did not work.

So I tried this:

http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-bsp/u-boot/u-boot_2011.06.bb?id=3994ad0c34b773b4887f1e6396ef86218a0e5c60

v2011.06

with

http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-bsp/u-boot/u-boot.inc?id=3994ad0c34b773b4887f1e6396ef86218a0e5c60

# GCC 4.5.1 builds unusable binaries using -Os, remove it from
OPTFLAGS
EXTRA_OEMAKE = "CROSS_COMPILE=${TARGET_PREFIX} OPTFLAGS='-O2'"

and at least I got a u-boot which is able to load a kernel.

All the network stuff from u-boot, which used to work some months ago
with git://github.com/koenkooi/u-boot.git seems to be bit rotten.

# v2011.12 tag

That works great on all my beagleboard when built with the angstrom toolchain. Maybe your toolchain is broken?

So I tried this:

u-boot_2011.06.bb « u-boot « recipes-bsp « meta - poky - Poky Build Tool and Metadata

v2011.06

with

u-boot.inc « u-boot « recipes-bsp « meta - poky - Poky Build Tool and Metadata

# GCC 4.5.1 builds unusable binaries using -Os, remove it from
OPTFLAGS
EXTRA_OEMAKE = "CROSS_COMPILE=${TARGET_PREFIX} OPTFLAGS='-O2'"

and at least I got a u-boot which is able to load a kernel.

All the network stuff from u-boot, which used to work some months ago
with git://github.com/koenkooi/u-boot.git seems to be bit rotten.

Networks works fine as well with the angstrom uboot binaries.

I figured in the meantime, that you can use u-boot mainline v2011.12
without and patched for the Beagle-xm rev C and compile __WITHOUT__
any special compiler tricks like replacing -Os with -O2.

Just copy MLO and u-boot.img, which are built from u-boot mainline
v2011.12, to the SD card and give it a try.

As Koen says even networking from u-boot is working out of the box
with it.
