Hi,
From the lasted Barebox version (barebox-2014.12.0):
I generated a MLO and a barebox.bin for the BeagleBone
(am335x_defconfig&am335x_mlo_defconfig config file) with the
modification of :
[PATCH] net: cpsw: Fix crashes on beaglebone black ledphilippe at
gmail.com
that I copied in a SD card. It work fine.
After, I wanted to boot from the the internal eMMC.
So after boot from sd card, I mounted the eMMC (mount /dev/mmc1.0) and
copied the MLO and barebox.bin in the /mnt/mmc1.0 folder.
When I try to boot from the internal eMMC ,I have the following error:
--------->
barebox 2014.12.0 #2 Wed Dec 31 15:29:16 GMT 2014
Board: TI AM335x BeagleBone
detected 'BeagleBone Black'
omap-hsmmc 48060000.mmc: registered as 48060000.mmc
booting from MMC
fat fat0: probe failed: error 22
Unable to mount (-22)
booting failed
<---------
I tried myself to find a 'correction' by added the call of
am33xx_of_register_bootdevice(void) function at the end of the static
int beaglebone_devices_init(void) function. With this modification,
sometime (depending of the last boot: from SD Card or from eMMC) I can
boot, someting not.
So my correction,although improving the situation, is not exactly the
correction to do. Some one can help me ?
Thanks very much !

This issue comes from commit:
commit 0d6392de4ad824a6553c0e3e3e18edef689a7c85
Author: Sascha Hauer <s.hauer@pengutronix.de>
Date: Thu Jun 5 12:09:07 2014 +0200
ARM: AM335x: Beaglebone: Use stripped down devicetree for MLO
For the MLO only the am335x-bone-common.dtsi is used to create the
device tree. But this does not have the emmc support included.

What you are also missing is a disabled emmc node from the
am335x-boneblack.dts in the am335x-bone-common.dtsi.
This may help.

In your bootlog above mmc@481d8000 (which is the eMMC) is not
registered. I had a quick look at the code and didn't find anything
obvious. I can have a closer look this evening.
