Hello,
I am looking for information on how to boot Linux with a device tree.
Basically, I have a uImage and a device tree(dtb) and with U-boot I
used to do:
bootm uImage_address -- dtb_address
How does it work with barebox?
Cheers,
Renaud

which architecture do you work on ARM/PPC?
on Arm I'm working on Mutli uImage support but I've not yet add the DTB
support
but you need to understand that on Barebox we do not use address but file
and in the case of the multi image index
Best Regards,
J.

As Jean-Christophe pointed out the architecture is important. On
Arm we do not have devicetree support in any official tree, but
I already have patches.

Thanks.
It would be for a ppc.
I am evaluating barebox on a mpc8544.

In this case it's bootm -o /some/blob /some/uImage
Note that this is likely to change in the near future as I'm working
on oftree support for ARM and will integrate libfdt then.

Can you share your experience with running Barebox on this e500 based chip?
Have you added anything to the generic arch/ppc/ code?
I'm currently working with an e500 based chip (P1011), so I'm very much
interested in your experience.
