But I believe It's like that for U-Boot older than v2022.04 ... and IMO we cannot ignore it. Said that from the code U-Boot looks into a `partition{}` node only as a direct child of the nand-controller, if there is a nand-chip in between the nand-controller{} and the partitions{} it will just ignore it. I could try to see what it is doing exactly, but I would need a little bit more time, I just tried changing the DTS as wrote I got a non bootable system. Francesco
