Prebuilt bootloaders
I have built the latest U-boot (2025.01-rc5) for Radxa Zero 3 (both W and E version supported): Bootloader storage Note: you have to extract the downloaded file first. How are they built? #!/bin/sh UB_TREE_PATH="/u-boot/u-boot-2025.01-rc5" cd $UB_TREE_PATH # rkbin: https://github.com/rockchip-linux/rkbin RKBIN="/rkbin/bin/rk35/" export BL31="$RKBIN/rk3568_bl31_v1.44.elf" export ROCKCHIP_TPL="$RKBIN/rk3566_ddr_1056MHz_v1.23.bin" gmake CROSS_COMPILE=aarch64-none-elf- distclean gmake CROSS_COMPILE=aarch64-none-elf- radxa-zero-3-rk3566_defconfig gmake CROSS_COMPILE=aarch64-none-elf- Most guide explains how to prepare an sd-card with both the OpenBSD installer...
