![]() There is no reasonably robust way (this will be needed so early that diagnostics will be limited) to specify the base-address of the secure timer through the DTS for TPL and SPL. In order to allow us a cleaner way to structure our SPL and TPL stage, we now move to a DM timer driver.

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- ARCH=arm > tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img > cat spl/u-boot-spl-dtb.bin >> spl-3368.img Build the full U-Boot and a FIT image including the ATF ======================================================= > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb Write to a SD-card ================== > dd if=spl-3368.img of=/dev/sdb seek=64 > dd if=u-boot.itb of=/dev/sdb seek=512 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...
