The hardware supported is not complete, but you can try it. You can use mainline u-boot master branch to boot OpenBSD. I build on linux with: git clone https://github.com/rockchip-linux/rkbin.git git clone https://source.denx.de/u-boot/u-boot.git cd u-boot export RKBIN_DIR=../rkbin/bin/rk35 export BL31="${RKBIN_DIR}/rk3528_bl31_v1.20.elf" export ROCKCHIP_TPL="${RKBIN_DIR}/rk3528_ddr_1056MHz_v1.11.bin" make CROSS_COMPILE=aarch64-linux-gnu- radxa-e20c-rk3528_defconfig make CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc) Then put on the SD card with: DEV=/dev/sdc wget https://ftp.fr.openbsd.org/pub/OpenBSD/snapshots/arm64/miniroot78.img dd of="${DEV}" if=miniroot78.img dd of="${DEV}" if=idbloader.img seek=64 dd of="${DEV}" if=u-boot.itb seek=16384 -- Vincent Legoll
