Hello,
Since the commit 0a37e22d638acf1b2c7c6e6ab83b6a3272b0a11c, I can't
boot my image anymore.
It seems that os_part is a null pointer and simple_strtoul crash on it
(in bootm_load_os). I workaround the problem by forcing the value to 0
if os_part if null, but I guess that it is a bad solution.
Is this a due to a bad usage of the mkimage utility?
best regards,

Probably not. Is this fixed by this commit?
commit 1a180cd3b6e5c067c68f3e09f7e15e5b18af9761
Author: Lucas Stach <l.stach@pengutronix.de>
Date: Fri Feb 12 17:58:23 2016 +0100
bootm: parse initrd and oftree into correct struct members
The code parsing the oftree and initrd file names is clearly wrong,
leading to bootm not loading oftree or initrd files any more.

This commit doesn't seem to fix the problem (in fact it was already
applied when I saw the crash).
Note: I am using mkimage to create bootable image of a real-time OS
(PikeOS). There is no initrd or dtc at this step for now: I guess it
is like loading an old Linux kernel without userspace.
I do not want to bother you with a specific use case if this is the
root of the problem.

So if you don't have an initrd, do you need uImage at all? You can boot
a bootable image directly
I use Linux without an initrd and don't bother with an uImage at all. I
have my kernel on the SD-CARD or eMMC in /boot/vmlinuz, just like on any
other (x86) Linux box.
Here is my env/boot/emmc script. I use "boot", not "bootm", but AFAIK boot uses
bootm under the hood.
global linux.bootargs.dyn.root="root=/dev/mmcblk0p${global.boot.partition} rootwait ro"
global bootm.image=/emmc/boot/vmlinuz
detect mmc3
mkdir -p /emmc
mount /dev/mmc3.0 /emmc
I have similar scripts for SD-Card and USB.
The kernel is installed using the normal Linux mechanism:
make -C ${KERNEL_DIR} ARCH=arm INSTALL_PATH=${IMAGE_DIR}/boot zinstall
maybe PikeOS has something equivalent. The result is:
$ file image/boot/vmlinuz-4.4.2
image/boot/vmlinuz-4.4.2: Linux kernel ARM boot executable zImage (little-endian)
As you see, I boot directly into the vmlinuz ... and I don't use
Barebox' CONFIG_DEFAULT_ENVIRONMENT_GENERIC_NEW, too.

Well, I do it this way because it was working I guess^^' but I tink
your proposition is the right think to do!
Thank you for the tip and the details, I'll check that and I'll give
you a feedback ASAP :)

Hi,
I managed to boot a 'raw' image. It is quite straightforward in fact.
Here is what I do:
addpart /dev/mem 0x10000000@0x10020000(sys)
uncompress raw.boot /dev/mem.sys
go 0x10020000
Thank you for your help :)
