Introduction[edit | edit source]
By default, AXEL ULite and SBC Lynx Embedded Linux Kit (XUELK) comes with a Yocto distribution. Nevertheless, other distributions can be used as well. This application note shows how to run one of them, Buildroot.
Buildroot is known to be very simple to configure and build. An exhaustive discussion of Buildroot is beyond the scope of this application note. The interested reader can refer for example to this presentation which compares in detail Yocto and Buildroot.
The test bed used for this application note is composed of the same hardware/software platform delivered along with the XUELK. About Buildroot, the version 2016.11.2 was used.
Donwloading, configuring and building[edit | edit source]
This process is straightforward. Once the file buildroot-2016.11.2.tar.gz is downloaded and decompressed on your Linux host machine, get into the Buildroot directory, and run make menuconfig.
Then enter the Target options menu and select:
ARM (little endian)forTarget Architecturecortex-A7forTarget Architecture Variant
as shown in the following picture.
That's it: after saving your configuration, and exiting menuconfig, you can start the build process by simply issuing the make command.
Mounting the Buildroot file system on the target[edit | edit source]
Once the build process is completed, in the output/images subdirectory the file rootfs.tar is available. This file contains the root file system for the target.
In this example, this file was untarred on a NFS server, in order to mount it via NFS protocol by the target. The following dump shows the serial console messages, printed out by the target during the boot process:
