For the record, we now have two platforms where we do FAT in PBL, which could be used as template: * arch/arm/boards/sama5d27* * arch/arm/boards/microchip-ksz9477-evb There are more that build two barebox images with separate configs, but recommendation is to do it in PBL, because you can then build both images at once.
