Cross compiler

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

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

Other option, use Linaro cross compiler 4.9.4 arm-gnueabi toolchain. Download here.

!!! Note DO NOT use hard-float variant (arm-linux-gnueabihf).

Compile U Boot

git clone https://github.com/helios-4/u-boot-marvell.git

cd u-boot-marvell

export ARCH=arm
export CROSS_COMPILE="/path/to/cross/compiler"
export CROSS_COMPILE_BH=${CROSS_COMPILE}

make mrproper

!!! note To compile using Ubuntu 16.04 cross compiler, please apply this patch to U-Boot source code.

To support Armbian boot script, please apply [this patch](/files/software/u-boot-armbian-boot-script-support.patch) to U-Boot source code.

SD Card image

./build.pl -f mmc -b armada_38x_helios4

it would produced u-boot-a38x-mm-d-mmc.bin whereas mm is month and d is day. For example, building u-boot on October 2nd would produced u-boot-a38x-10-2-mmc.bin

SPI NOR flash image

./build.pl -f spi -b armada_38x_helios4

it would produced u-boot-a38x-mm-d-spi.bin whereas mm is month and d is day. For example, building u-boot on October 2nd would produced u-boot-a38x-10-2-spi.bin
