Buildroot 2016.02 on XTERM-01

This article illustrates how to generate from sources a BuildRoot 2016.02 distribution for XTERM-01

Building BuildRoot from sources

Follow this article:

using acme-xterm-01_defconfig in this way instead of use other buildroot configuration.

~/buildroot-2016.02$ make acme-xterm-01_defconfig

The file acme-xterm-01_defconfig is created by the patches applied in this article on the standard Buildroot distribution.

Compile Linux

Follow this article:

using acme-xterm-01_defconfig to generate the Linux config:

~/linux-4.4.11$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- acme-xterm-01_defconfig

and acme-xterm-01.dts as device tree:

~/linux-4.4.11$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- acme-xterm-01.dtb

These files are created by applying the patches listed inside the articles.

Copying the file on the first uSD partition

~/linux-4.4.11$ cp arch/arm/boot/dts/acme-xterm-01.dtb /media/$USER/boot/acme-arietta.dtb
~/linux-4.4.11$ cp arch/arm/boot/zImage /media/$USER/boot
~/linux-4.4.11$ sudo rsync -avc modules/lib/. /media/$USER/rootfs/lib/.

Try a Qt example

Get the access to the board using the DPI interface or via SSH.

Login with as root using the password acmesystems

Calibrate the touchscreen by typing:

# ts_calibrate

then try one of the Qt example available:

# cd /usr/share/qt/examples/widgets/sliders
# ./sliders 

now run this command in order to set Qt to use tslib:

# export QWS_MOUSE_PROTO=Tslib:/dev/input/event0

then launch the first example (see the video):

# /sliders -qws
