When building U-Boot we select the architecture via Kconfig and not ARCH being passed in via the environment or make cmdline.

Here is the step-by-step to boot to U-Boot on RK3368-uQ7 Get the Source and build ATF ============================ > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git > cd arm-trusted-firmware > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31 > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin Configure U-Boot ================ > cd ../u-boot > make lion-rk3368_defconfig Build the TPL/SPL stage ======================= > make CROSS_COMPILE=aarch64-unknown-elf- Build the full U-Boot and a FIT image including the ATF ======================================================= > make CROSS_COMPILE=aarch64-unknown-elf- u-boot.itb Flash the image =============== Copy the SPL to offset 32k and the FIT image containing the payloads (U-Boot proper, ATF, devicetree) to offset 256k card. SD-Card ------- > dd if=idbloader.img of=/dev/sdb seek=64 > dd if=u-boot.itb of=/dev/sdb seek=512 eMMC ---- rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with help of the Rockchip loader binary. > git clone https://github.com/rockchip-linux/rkdeveloptool > cd rkdeveloptool > autoreconf -i && && ./configure && make > git clone https://github.com/rockchip-linux/rkbin.git > ./rkdeveloptool db rkbin/rk33/rk3368_loader_v2.00.256.bin > ./rkdeveloptool wl 64 ../spl.img > ./rkdeveloptool wl 512 ../u-boot.itb If everything went according to plan, you should see the following output on UART0: <debug_uart> U-Boot TPL board init Trying to boot from BOOTROM Returning to boot ROM...
