SPI now contains U-Boot SPL 2026.01 and it boots the current kernel 6.18.63 off emmc: So in order to make sure there is 'only one captain on the ship' I erased the boodloader on emmc, force installed u-boot-rock-5b-edge and flashed it to SPI: sudo dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=64 count=8128 conv=notrunc
sudo dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=16384 count=16384 conv=notrunc
sudo dpkg -i --force-all linux-u-boot-rock-5b-edge_26.11.0-trunk.129_arm64__2026.01-S127a-Pec93-H9409-Vc955-B3ba1-R448a.deb
sudo dd if=zero.img of=/dev/mtdblock0 #zero.img from radxa
cd /lib/linux-u-boot-edge-rock-5b
sudo dd if=u-boot-rockchip-spi.bin of=/dev/mtdblock0
strings /dev/mtd0 | grep 'U-Boot SPL 20'
U-Boot SPL 2026.01_armbian-2026.01-S127a-Pec93-H9409-Vc955-B3ba1-R448a (Nov 10 2026 - 12:25:38 +0000)
