This is a quickstart guide to build Yocto BSP for Axel SOMs, to rebuild the binaries (u-boot, linux kernel, root file system) provided with XELK releases.
For more information regarding Yocto build system, go to its dedicated category page
Build System prerequisite[edit | edit source]
Please read the Yocto manual setup section for a list of supported Linux distribution and their configuration.
DAVE Embedded System uses a standard Ubuntu 12.04.4 LTS Server 64 bit distribution plus the following additional packages:
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat libsdl1.2-dev xterm
Build Axel Yocto BSP[edit | edit source]
Bora Yocto BSP uses git-repo tool to fetch all the required git repositories to build
dvdk@dvdk-vm:~/belk$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > repo dvdk@dvdk-vm:~/belk$ chmod a+x repo dvdk@dvdk-vm:~/belk$ ./repo init -u git@git.dave.eu:dave/axel/axel-bsp.git -b axel dvdk@dvdk-vm:~/belk$ ./repo sync dvdk@dvdk-vm:~/belk$ source axel-bsp-init-env.sh build dvdk@dvdk-vm:~/belk/build$ bitbake base-rootfs-image
Please note that even the basic root file system requires a few hours to build on a mid-hi range desktop (4-6 cores, 8-12 GiB RAM) also depending on your Internet connection speed (all sources are fetched from the network). Nearly 20GiB of disk space is required for the build.
The resulting files (kernel, devicetree and u-boot binaries, plus .tar.gz root file system) will then be available inside build/tmp/deploy/images/axel.
Build additional packages[edit | edit source]
To build additional packages the user must first enter the directory where the bora-bsp-init-env.sh is placed and source it
dvdk@dvdk-vm:~/xelk$ source bora-bsp-init-env.sh build dvdk@dvdk-vm:~/xelk/build$
And then can run any of the [bitbake] command.
dvdk@dvdk-vm:~/xelk/build$ bitbake memtester
The resulting packages (the default format is ipk) can be found inside build/tmp/deploy/ipk.
dvdk@dvdk-vm:~/xelk/build$ ls -l tmp/deploy/ipk/armv7a-vfp-neon/memtester* -rw-r--r-- 2 dvdk dvdk 7102 Aug 26 16:33 tmp/deploy/ipk/armv7a-vfp-neon/memtester_4.1.3-r0_armv7a-vfp-neon.ipk -rw-r--r-- 2 dvdk dvdk 21720 Aug 26 16:33 tmp/deploy/ipk/armv7a-vfp-neon/memtester-dbg_4.1.3-r0_armv7a-vfp-neon.ipk -rw-r--r-- 2 dvdk dvdk 792 Aug 26 16:33 tmp/deploy/ipk/armv7a-vfp-neon/memtester-dev_4.1.3-r0_armv7a-vfp-neon.ipk -rw-r--r-- 2 dvdk dvdk 2748 Aug 26 16:33 tmp/deploy/ipk/armv7a-vfp-neon/memtester-doc_4.1.3-r0_armv7a-vfp-neon.ipk
