i.MX53 SODIMM PC - Development kit uses Barebox as a bootloader. This page displays how to configure and build it.<br /><br />

Barebox is a bootloader responsible for hardware initialization, loading and booting Linux kernel. It is also used for module flashing.

== Building images ==

=== Set toolchain ===
Export [[i.MX53_SODIMM_PC_Toolchain|toolchain variables]] for every related terminal session.

=== Set shell variables ===
<syntaxhighlight lang="bash">
BB_VERSION=2014.03.0
SW_VERSION=20150308
</syntaxhighlight>

=== Download and extract source code ===
<syntaxhighlight lang="bash">
mkdir -pv ~/workdir/vmx53/barebox/
cd ~/workdir/vmx53/barebox/
wget http://barebox.org/download/barebox-${BB_VERSION}.tar.bz2
tar xvjf barebox-${BB_VERSION}.tar.bz2
mv barebox-${BB_VERSION} barebox-${BB_VERSION}.orig
cp -rv barebox-${BB_VERSION}.orig barebox-${BB_VERSION}.work
</syntaxhighlight>

=== Download Voipac patches ===
<syntaxhighlight lang="bash">
cd ~/workdir/vmx53/barebox/
wget http://downloads.voipac.com/files/i.MX53_SODIMM_PC-Development_kit/module/software/barebox/sources/barebox-2014.03.0_vmx53_20151129.cfg
wget http://downloads.voipac.com/files/i.MX53_SODIMM_PC-Development_kit/module/software/barebox/sources/barebox-2014.03.0_vmx53_20151129.patch
cd ~/workdir/vmx53/barebox/barebox-${BB_VERSION}.work
patch -p1 < ../barebox-${BB_VERSION}_vmx53_${SW_VERSION}.patch
cp ../barebox-${BB_VERSION}_vmx53_${SW_VERSION}.cfg .config
</syntaxhighlight>

=== Compile ===
Output file is called arch/arm/pbl/zbarebox.bin:
<syntaxhighlight lang="bash">
cd ~/workdir/vmx53/barebox/barebox-${BB_VERSION}.work
#make ARCH=arm menuconfig
make -j4
</syntaxhighlight>

== Configure ==

=== Edit boot options ===

Barebox provides 4 boot configurations by default:
* nand-legacy-ubi
** Load kernel (nand - kernel)
** Attach rootfs (nand - rootfs)
* nand-dtb-ubi
** Load kernel (nand - kernel)
** Load device tree (nand - bareboxenv)
** Attach rootfs (nand - rootfs)
* net-legacy
** Load kernel (tftp)
** Attach rootfs (nfs)
* net-dtb
** Load kernel (tftp)
** Load device tree (tftp)
** Attach rootfs (nfs)
<br /><br />
Boot configuration files include options to define custom kernel and rootfs names or paths:
<syntaxhighlight lang="bash">
barebox@Voipac VMX53:/ edit /env/boot/net-dtb
</syntaxhighlight>

<syntaxhighlight lang="bash">
barebox@Voipac VMX53:/ edit /env/config

# list of boot entries. These are executed in order until one
# succeeds. An entry can be:
# - a filename in /env/boot/
# - a full path to a directory. All files in this directory are
# treated as boot files and executed in alphabetical order
global.boot.default=nand-dtb-ubi
</syntaxhighlight>

=== Set correct DTB file based on module configuration ===
Each configuration uses an altered device tree:
<syntaxhighlight lang="bash">
barebox@Voipac VMX53:/ edit /env/config
...
# BASIC=557, PRO=668, MAX=779
#global.vmxmodel=557
global.vmxmodel=668
#global.vmxmodel=779
...
barebox@Voipac VMX53:/ saveenv
barebox@Voipac VMX53:/ reset
</syntaxhighlight>
