zjd Posted 3 hours ago Posted 3 hours ago (edited) I updated to Armbian 26.2.1 on OPi5, and it can't boot from MTD (rootfs at NVMe), and I have to use SD card to boot to NVMe as workaround. After looking into this issue, I found rkspi_loader.img is no longer available for current (6.18.8 kernel) u-boot pkg and armbian-config flashes u-boot-rockchip-spi.bin ( or similar sata version) to /dev/mtdblock0 and I think this is wrong image for MTD bootloader. If I use older vendor image, which u-boot pkg has rkspi_loader.img, system can boot to NVMe rootfs and I notice that /dev/mtdblock0 has several gpt partitions including u-boot one, and flashing u-boot-rockchip-spi.bin erases partitions in SPI flash. I noticed that several related changes were introduced since 25.11, such as https://github.com/armbian/build/commit/e5b845f9432abb0408287599bba5889a86e6d068 , but I couldn't do quick fix to bring back working rkspi_loader.img because I am not familiar with whole armbian build. One thing to note that if board was flashed with old rkspi_loader.img and not updated with 26.2 MTD image, it still boots to NVMe rootfs, but I have other issues such as video playback not working with 6.18 kernel likely due to mismatch u-boot and kernel version leading to wrong HW initialization. BTW, I checked 26.2 u-boot pkg for Rock 5B (similar rk3588 board), and rkspi_loader.img is still included. Edited 3 hours ago by zjd 0 Quote
