Download U-Boot

Upstream U-Boot

You can clone the u-boot repository by running:

git clone https://gitlab.denx.de/u-boot/u-boot.git

Alternatively you can use u-boot-rockchip instead which may with some patches not get in mainline:

git clone https://gitlab.denx.de/u-boot/custodians/u-boot-rockchip.git

Rockchip U-Boot

You can clone the u-boot repository by running:

git clone https://github.com/rockchip-linux/u-boot.git

Supported Devices

Upstream U-Boot support Rockchip SoCs:

RK3036, RK3188, RK3288, RK3328, RK3399

RK3036 boards supported:

EVB RK3036 - use evb-rk3036 configuration
Kylin - use kylin_rk3036 configuration

RK3288 boards supported:

EVB RK3288 - use evb-rk3288 configuration
Firefly RK3288 - use firefly-rk3288 configuration

RK3328 boards supported:

EVB RK3328 - use evb-rk3328 configuration

RK3399 boards supported:

EVB RK3399 - use evb-rk3399 configuration

Get a toolchain

If you haven't done so before, get a suitable toolchain installed and add it to your PATH.

In Ubuntu 14.04, you can use below command to install cross compiler for armv7:

sudo apt-get install gcc-arm-linux-gnueabi

Or for ARM64

sudo apt-get install gcc-aarch64-linux-gnu

Note that the latest U-Boot require version gcc-5.0 and later, we recommand to use linaro 6.3.1.

https://github.com/rockchip-linux/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.git

https://github.com/rockchip-linux/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.git

Build U-Boot

Configure U-Boot

First you need to choose a correct defconfig for your board;

When you have determined what <board_name> you want to build, configure:

make CROSS_COMPILE=arm-linux-gnueabi- <board_name>_defconfig

You may need to change the U-Boot function/feature support by modify the defconfig file or,

there is also menuconfig to play with settings if you feel like it:

make CROSS_COMPILE=arm-linux-gnueabi- menuconfig

Buid Rockchip U-Boot

For convenience, Rockchip provide a script 'make.sh' to make it easy to get everything before kernel, this script need toolchain and rkbin support.

expample for build rk3399:

./make.sh rk3399

and use './make.sh -h' for more option.

The output will including pre-loader, trust and u-boot image which is ready to use with rockchip upgrade tool,

Build Upstream U-Boot

This is common and available for both Upstream U-Boot and Rockchip U-Boot.

For armv7:

make CROSS_COMPILE=arm-linux-gnueabi-

or for ARM64:

make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-

In order to support debug symbol in ARM DS-5, you may need add ctags in make command:

CFLAGS='-gdwarf-3'

The output including u-boot.bin, spl/u-boot-spl.bin, tpl/u-boot-tpl.bin at this step, and you need to package it with mkimage tool before use with rockchip upagrade tool. Get detail at boot option.

Support ATF with SPL FIT image

For trust support in SPL, we are using FIT image with 'mkimage' cmd in Makefile and its script defined in defconfig:

make u-boot.itb

Note: please copy the trust binary(optee.bin or bl31.elf from rkbin project) to u-boot root directory and rename it to tee.bin(armv7) or bl31.elf(armv8).

The output u-boot.itb is a its based package including u-boot-nodtb.bin, board.dtb, and trust binaries which can be used directly with upgrade tool.

Install U-Boot

See boot option about how to

- package the available binaries

- flash and boot from eMMC/SD card.

Boot cmd

Rockchip U-Boot supports image type:

Android boot(boot_android), Rockchip RKIMG boot(boot_rockchip) and LInux distro boot(distro_bootcmd).

Upstream U-Boot supports image type::

Linux distro boot(distro_bootcmd).

Firmware download in U-Boot

In U-Boot, there are multi way to update image into emmc via U-Boot, you can chose any of one easy use for you.
