Thank you very much for your reply, Werner - and indeed for all the tremendous work you do! The drive is listed as an /dev/nvme0n1p1, so I think I did choose the right overlay. Rootfs UUID is correct. I tested SPI/MTD boot with Armbian 26.2.1, rootfs on NVMe. I erased and reflashed the SPI flash manually: ``` shell sudo flash_eraseall /dev/mtd0 sudo dd if=/usr/lib/linux-u-boot-vendor-orangepi5/u-boot-rockchip-spi.bin \ of=/dev/mtdblock0 bs=1M conv=fsync status=progress sync ``` I then verified that the running system was still using /boot from the SD card: ``` shell findmnt /boot ``` which returned: ``` shell /boot /dev/mmcblk1p1[/boot] ``` I mounted the NVMe rootfs and compared /boot on SD vs NVMe: ``` shell sudo mkdir -p /mnt/nvme sudo mount /dev/nvme0n1p1 /mnt/nvme ls -la /boot ls -la /mnt/nvme/boot ``` The NVMe /boot contents were older/stale compared with the SD /boot, so I synchronized them: ``` shell sudo rsync -aHAX --delete /boot/ /mnt/nvme/boot/ sync ``` I then powered the board off completely, removed the SD card, and tested booting from SPI + NVMe again but it still won't boot without the SD card. I watched your video on UART debugging, but unfortunately, my serial cable is too slow, so I'll get one of those you recommend and try again. Thanks again!

Hi everyone, I just got an Orange Pi 5 and am experiencing the same issue as the OP. I've since then installed the bootloader on the SD card and the rootfs on the NVME drive. I don't really understand what came out of the discussion here: is it possible to boot from the MTD? Thanks a lot! EV
