As mentioned in the other mail, it's in the barebox device tree and on Linux boot fixed up into the Linux device tree. > Anyhow I compiled a zeus image using the old barebox version 2017.12.0 and bootchooser works again with zeus. > Interesting is that ubi fails too like in thud. So it seems as long as ubi fails state could be used or the other way around. I don't think they are related. It would be best if you can try to reproduce this issue with upstream barebox. To do so without yocto: git clone https://git.pengutronix.de/git/barebox cd barebox cp $your_barebox_config_in_yocto .config make -j$(nproc) CROSS_COMPILE=/path/to/your/yocto/toolchain/bin/arm-$your_vendor-linux-gnueabihf- ARCH=arm under images/ you will have the barebox images. You can get that onto your device using a SD-Card, imx-usb-loader, tftp ... etc. If you want to do it in Yocto, there are meta-ptx and meta-barebox that have more recent barebox versions.
