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
|
||
|
|
|
||
|
|
Build the full U-Boot and a FIT image including the ATF
|
||
|
|
=======================================================
|
||
|
|
|
||
|
|
> make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm 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
