Hello,

I am currently trying to bring up barebox for my Beaglebone Black devices.

I did an "ARCH=arm CROSS_COMPILE=arm-buildroot-linux-gnueabihf- make am335x_mlo_defconfig”, make and
copied resulting barebox-am33xx-beaglebone-mlo.img to MLO into my FAT boot partition.

Then I did "ARCH=arm CROSS_COMPILE=arm-buildroot-linux-gnueabihf- make omap3530_beagle_defconfig”, make 
and copied resulting barebox-beagleboard.img to barebox.bin into my boot FAT.

Is the the different prefix in the defconfigs (am33… vs. omap35…) reasonable? 
Is this approach generally reasonable?

Many references in internet to matching
defconfigs I found refer to non existing ones, there seems to happen great overhaul meanwhile. 
I am also asking because, well, it does not work:

barebox 2021.05.0-00093-g7689055a8 #2 Fri Jun 11 09:01:36 CEST 2021

This repeats endlessly. I investigated the data sheet and if I am correct 0x4020f010 seems to be a reserved
