Grab some firmware files:
git clone https://github.com/rockchip-linux/rkbin.git
dd if=rkbin/rk33/rk3399_ddr_666MHz_v1.08.bin of=ddr.bin bs=4 skip=1 mkimage -T rksd -n rk3399 -d ddr.bin idbloader.img cat rkbin/rk33/rk3399_miniloader_v1.06.bin >> idbloader.img
rkbin/tools/loaderimage --pack --uboot u-boot.bin uboot.img
To flash mainline-based U-Boot, connect the USB Type-C connector to a USB port of another openSUSE system and short the eMMC pads on power-on to enter MaskRom mode.
Use rkdeveloptool package to flash U-Boot:
rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin rkdeveloptool wl 0x40 idbloader.img rkdeveloptool wl 0x4000 uboot.img rkdeveloptool wl 0x6000 rkbin/img/rk3399/trust.img rkdeveloptool rd
