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
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.
sudo apt -y install gcc-arm-linux-gnueabihf binutils-arm-linux-gnueabihf
Setup environment for cross compiling.
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.
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.
Setup environment for cross compiling.
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
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 to U-Boot source code before
*make helios4_defconfig*
SD Card image
make -j$(nproc)
it would produced u-boot-spl.kwb
SPI NOR flash image
Since helios4_defconfig targeting SD card image, we need to modified the configuration to generate SPI NOR flash image before compiling.
mv -f .config .config_mmc
awk '{\
gsub(/CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC=y/,"# CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC is not set");\
gsub(/# CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI is not set/,"CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI=y");\
gsub(/CONFIG_ENV_IS_IN_MMC=y/,"# CONFIG_ENV_IS_IN_MMC is not set");\
gsub(/# CONFIG_ENV_IS_IN_SPI_FLASH is not set/,"CONFIG_ENV_IS_IN_SPI_FLASH=y");\
}1' .config_mmc >> .config
rm -f .config_mmc
make -j$(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
sudo apt-get -y install libncurses5-dev
Launch configuration editor
make menuconfig
After exiting the configuration editor and saving the configuration, build the image according to SD Card image or SPI NOR flash image instructions.
Marvell U-Boot 2013.01
Based on U-Boot 2013.01 Marvell version: 2015_T1.0p16
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.scr), 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
Write U-Boot to Boot Device
MicroSD Card
!!! note Replace u-boot-spl.kwb with u-boot-a38x-*-mmc.bin in command below if you are using Marvell U-Boot 2013.01
On Development PC
-
Put SD card to Memory Card Reader
-
Write U-Boot image (u-boot-spl.kwb) to Memory Card Reader (eg. /dev/sdc) and reboot
sudo dd if=u-boot-spl.kwb of=/dev/sdc bs=512 seek=1 status=noxfer
sudo sync
- Remove the SD card and put it to Helios4.
Live System - Under Armbian
- Upload the U-Boot SPI binary that you built on your PC to Helios4 and rename it as u-boot.mmc.
scp u-boot-spl.kwb root@10.10.10.1:/usr/lib/linux-u-boot-next-helios4_*/u-boot.mmc
- SSH to Helios4
ssh root@10.10.10.1
- Run nand-sata-install utility
sudo nand-sata-install
- Select option Install/Update the bootloader on SD/eMMC
- Confirm the operation
- Reboot the system
Live System - Generic Linux
- Transfer U-Boot image into home folder in Helios4 using scp
scp u-boot-spl.kwb root@10.10.10.1:~/
- SSH to Helios4
ssh root@10.10.10.1
- Write U-Boot image (u-boot-spl.kwb) to SD Card device (/dev/mmcblk0) and reboot
sudo dd if=u-boot-spl.kwb of=/dev/mmcblk0 bs=512 seek=1 status=noxfer
sudo reboot
