It does reference barebox in to esdhc not in qspi This would explain why barebox_update -l doesn't list qspi, but you aren't getting that far, apparently. > I am programming barebox into the QSPI with barebox-ls1046ardb-qspi.image Could that be why it is not running, having no QSPI node enabled? > I guess I need to augment arch/arm64/dts/fsl-ls1046a-rdb.dts to have QSPI support. > Not too familiar with the use of DTB in barebox at present. That shouldn't matter. barebox header should contain the necessary bits for muxing/clocks. Device-Tree only becomes relevant later, when barebox itself needs to read/write the flash. I'd postpone QSPI for now and check whether SD-Card boot works at all.
