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.
!!! note To support Armbian boot script (/boot/boot.src), please apply this 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
