## 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](/helios4/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
|
|
```
|
|
|
|
|
|
|
|
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.

## 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.
|
|
|
|
```bash
|
|
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](https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/arm-linux-gnueabi/).
|
|
|
|
!!! Note
|
|
DO NOT use hard-float variant (arm-linux-gnueabihf).
|
|
|
|
### Compile U-Boot
|
|
|
|
```bash
|
|
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](https://github.com/armbian/build/blob/master/patch/u-boot/u-boot-mvebu/tools-bin_hdr-compiler-fixes.patch) to U-Boot source code.
|
|
|
|
!!! note
|
|
To support Armbian boot script (/boot/boot.scr), please apply [this patch](/helios4/files/uboot/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*
|
|
|
|
## 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
|
|
|
|
1) Put SD card to Memory Card Reader
|
|
|
|
2) 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
|
|
```
|
|
|
|
3) Remove the SD card and put it to Helios4.
|
|
|
|
|
|
#### Live System - Under Armbian
|
|
|
|
1) 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
|
|
```
|
|
|
|
2) SSH to Helios4
|
|
|
|
```
|
|
ssh root@10.10.10.1
|
|
```
|
|
|
|
3) Run **nand-sata-install** utility
|
|
|
|
```
|
|
sudo nand-sata-install
|
|
```
|
|
|
|
4) Select option **Install/Update the bootloader on SD/eMMC**
|
|
|
|
|
|
|
|
5) Confirm the operation
|
|
|
|
|
|
|
|
6) Reboot the system
|
|
|
|
|
|
#### Live System - Generic Linux
|
|
|
|
1) Transfer U-Boot image into home folder in Helios4 using scp
|
|
|
|
```
|
|
scp u-boot-spl.kwb root@10.10.10.1:~/
|
|
```
|
|
|
|
2) SSH to Helios4
|
|
|
|
```
|
|
ssh root@10.10.10.1
|
|
```
|
|
|
|
3) 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
|
|
```
|
|
|
|
### SPI NOR Flash
