I have a sama5d3_xplained here with NAND, which I will try to find some time to reproduce this on. For your immediate issue: I'd like to use the occasion to get all sama5d3 to probe from device tree. We already have one sama5d3 DT-enabled board upstream (microchip-ksz9477-evb) and I just CC'd you on a series to migrate the sama5d3_xplained from legacy board code to DT. I tested this boots correctly after at91bootstrap from NAND without your series here. The relevant defconfig is at91_multi_defconfig. It will generate a barebox-sama5d3-xplained.img, which should boot to shell on your board. If that works, we could create a new barebox-sama5d3xek.img image that does the same as barebox-sama5d3-xplained.img, but with different device tree and see if all peripherals you use still work. With everything nice and dandy, we could finally remove non-DT code for sama5d3 altogether and your board would reuse the same early bootstrap code basically all other platforms use and test. Sounds good?
