## Cross compiler
## U-Boot 2018
Based on mainline U-Boot.
### Dependencies
- bison (YACC-compatible parser generator)
- flex (fast lexical analyzer generator)
- bc (GNU bc arbitrary precision calculator language)
- openssl/bn.h header (Secure Sockets Layer toolkit - development files)
- make (GNU Make)
- gcc (GNU C Compiler)
Under Debian / Ubuntu, the dependencies can be installed using
```bash
sudo apt-get -y install bison flex bc libssl-dev make gcc
```
### Cross compiler
Even though mainline U-Boot requires GCC minimum version 6, it would generate oversized SPL (Secondary Program Loader) image. Therefore it is recommended to use GCC version 7.
#### Ubuntu 18.04 LTS
Install the toolchain.
```bash
sudo apt -y install gcc-arm-linux-gnueabihf binutils-arm-linux-gnueabihf
```
Setup environment for cross compiling.
```bash
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
```
#### Other OS/ Distribution
Other OS / Distribution that does not have GCC version 7 such as Debian, should use Linaro arm-linux-gnueabihf toolchain.
Download and extract the toolchain.
```bash
cd ~
wget http://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/arm-linux-gnueabihf/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz
tar Jxf gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz
```
!!! note
Latest Linaro toolchain version 7 can be found [here](http://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabihf/).
Setup environment for cross compiling.
```bash
export ARCH=arm
export CROSS_COMPILE=~/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
```
### Compile U-Boot
```bash
git clone https://github.com/helios-4/u-boot.git -b helios4
cd u-boot
make mrproper
make helios4_defconfig
```
!!! note
To support Armbian boot script (/boot/boot.scr), please apply [this patch](/files/uboot/u-boot-mainline-armbian-boot-script-support.patch) to U-Boot source code before
*make helios4_defconfig*
#### SD Card image
```bash
make -j$(nproc)
```
it would produced **u-boot-spl.kwb**
#### SPI NOR flash image
Since *helios4_defconfig* targeting SD card image, we need to modified the configuration to generate SPI NOR flash image before compiling.
```bash
mv -f .config .config_mmc
awk '{\
gsub(/CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC=y/,"# CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC is not set");\
gsub(/# CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI is not set/,"CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI=y");\
gsub(/CONFIG_ENV_IS_IN_MMC=y/,"# CONFIG_ENV_IS_IN_MMC is not set");\
gsub(/# CONFIG_ENV_IS_IN_SPI_FLASH is not set/,"CONFIG_ENV_IS_IN_SPI_FLASH=y");\
}1' .config_mmc >> .config
rm -f .config_mmc
make -j$(nproc)
```
it would produced **u-boot-spl.kwb**
### Customize U-Boot
U-Boot has configuration editor based on ncurses similar like Linux Kernel configuration editor.
Install ncurses development files. Under Debian/Ubuntu can be done using this command
```bash
sudo apt-get -y install libncurses5-dev
```
Launch configuration editor
```bash
make menuconfig
```
![menuconfig main](/img/u-boot/u-boot_menuconfig_main.png)
After exiting the configuration editor and saving the configuration, build the image according to [SD Card image](#sd-card-image) or [SPI NOR flash image](#spi-nor-flash-image) instructions.

Under Debian / Ubuntu you need first to install the necessary packages and tools for cross compiling for ARM.
