Hi Robert In the original case the board just reboots when the Barebox is to be loaded from the bootstream image. In log below you see that the power_prep and boot_prep is run but the Barebox is not started at all. So, in this case there is no Barebox issue, but I was looking for if there are some mechanism for handling boot environment, kernel load etc with Bad block management. For example something like writing and loading a kernel image, using skip block method, from a partition with bad blocks and image cannot be stored over linear addresses. Booting an image where Barebox is stored in a NAND Bad Block: PowerPrep start initialize power... Configured for 5v only power source. Battery powered operation disabled.

Is it possible to have a look at the fails?
