=== Build ROCK Pi E U-Boot ===

Below is the instructions of how to build U-Boot for ROCK Pi E on a '''HOST PC'''.

==== Get the source code ====

You need Git to get multiple git repositories to build the image.

Install Git if you don't have it.

sudo apt-get update
sudo apt-get install git

Clone the source code

git clone -b stable-4.4-rockpie https://github.com/radxa/u-boot.git
git clone -b debian https://github.com/radxa/build.git
git clone -b master https://github.com/radxa/rkbin.git

You will get

build rkbin u-boot

Directories usage introductions:

* build:
** Some script files and configuration files for building u-boot, kernel and rootfs.
* rkbin:
** Prebuilt Rockchip binaries, include first stage loader and ATF(Arm Trustzone Firmware).
* u-boot:
** u-boot as the second stage bootloader

==== Install toolchain from Linaro ====

wget https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz
sudo tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz -C /usr/local/
export CROSS_COMPILE=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
export PATH=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin:$PATH

Check if Linaro toolchain is the default choice:

which aarch64-linux-gnu-gcc
/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc

==== Install other build tools ====

sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev mtools
sudo apt-get install bc python dosfstools

==== Build u-boot ====

Need to checkout branch to '''stable-4.4-rockpie'''.

Build u-boot with default '''rock-pi-e-rk3328_defconfig'''.

./build/mk-uboot.sh rockpie #For ROCK Pi E

The generated images will be copied to out/u-boot folder

ls out/u-boot/
idbloader.img rk3328_loader_ddr333_v1.16.250.bin trust.img uboot.img
