How to compile the U-Boot for Rugged Board A5d2x
This guide describes a method of compile the u-boot for rugged board a5d2x.
- PC(Personal computer)/System
- Ubuntu 16.04
The following list shows what you need in order to use a Linux-based build host to build images:
- Build Host A build host with a minimum of 50 Gbytes of free disk space that is running a supported Linux distribution (i.e. recent releases of Fedora, openSUSE, CentOS, Debian, or Ubuntu).
- Build Host Packages Appropriate packages installed on the build host.
The following list shows the required packages needed to build an image that runs on QEMU in graphical mode.
Ubuntu and Debian:
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat libsdl1.2-dev xterm
Step1: Create a directory to download the u-boot source.
$ mkdir uboot_source
cd uboot_source
Step2: Clone uboot-rba5d2x with the proper branch.
$ git clone https://github.com/rugged-board/uboot-rba5d2x.git
$ cd uboot-rba5d2x
$ git checkout origin/uboot-rba5d2x
Step3: Before configuring the u-boot,Please run the arm environment to cross compile the downloaded u-boot source. If you dont have arm toolchain, please follow step4 to download the toolchain.
$ . /opt/poky-tiny/2.5.2/environment-setup-cortexa5hf-neon-poky-linux-musleabi
Step4: If you haven't downloaded the toolchain before please follow below link.
Step5: Configure the u-boot for NOR Flash of rugged board a5d2x.
$ make rugged_board_a5d2x_qspiflash_defconfig
Step6: Compile the u-boot for NOR Flash of rugged board a5d2x using below command.
$ make
step7: Configure the u-boot for SDCard Flash of rugged board a5d2x.
$ make rugged_board_a5d2x_mmc1_defconfig
Step8: Compile the u-boot for SDCard Flash of rugged board a5d2x using below command.
$ make
Step9: After compiling the u-boot source, get the u-boot.bin in the current uboot-rba5d2x source directory.
