More details about the Yocto Environment Setup can be found
[https://www.yoctoproject.org/docs/2.6/brief-yoctoprojectqs/brief-yoctoprojectqs.html#brief-build-system-packages on the Yocto official site]

= Download Yocto based on Freescale Community BSP =

$ git config --global user.name "Your Name"
$ git config --global user.email "Your Email"

$ mkdir ~/bin
$ {{#var:CURL}} <nowiki>http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo</nowiki>
$ chmod a+x ~/bin/repo
$ export PATH=~/bin:$PATH

$ mkdir {{#var:BUILD_FOLDER}}
$ cd {{#var:BUILD_FOLDER}}

* '''Download the Yocto repository'''<br>
$ repo init -u https://github.com/ronetix/bsp-repo -u dunfell

$ repo sync

= Setup and build Yocto =
$ MACHINE=imx8mq-cm DISTRO=fslc-xwayland . setup-environment build_xwayland_mx8mq_cm
$ bitbake fsl-image-gui

== Build Results ==
The resulted images are located in tmp/deploy/images/{{#var:MACHINE_NAME}}.

== Create a bootable SD card ==
Replace sdX with the right device name.
$ umount /dev/sdX1
$ umount /dev/sdX2
$ sudo bmaptool copy tmp/deploy/images/{{#var:MACHINE_NAME}}/fsl-image-gui-{{#var:MACHINE_NAME}}.wic.gz /dev/sdX

= WiFi Setup =
Scan for wireless networks:
$ ifconfig wlan0 up
$ iw dev wlan0 scan | grep SSID

Connecting to an Access Point:
$ wpa_passphrase <YourAP> <YourPassword> > /etc/wpa_supplicant.conf
$ wpa_supplicant -B -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf

wait for:
$ wlcore: Association completed.

Get an IP via DHCP:
$ udhcpc -i wlan0
$ ifconfig

= Audio Test =
List all sound cards:
$ aplay -L

Play a file:
$ aplay Test.wav

List all sound controls:
$ amixer controls

Set Speaker Playback volume to max:
$ amixer cset numid=13 127

= QSPI NOR Flash test =
$ mtd_debug info /dev/mtd0
$ mtd_debug erase /dev/mtd0 0 0x10000
$ dd if=/dev/urandom of=tmp_write.txt bs=1024 count=64
$ dd if=tmp_write.txt of=/dev/mtd0 bs=1024 count=64
$ dd if=/dev/mtd0 of=tmp_read.txt bs=1024 count=64
$ diff tmp_write.txt tmp_read.txt
$ hexdump -C tmp_read.txt | more

= I2C EEPROM Test =
$ echo "Ronetix GmbH" > /sys/bus/i2c/devices/0-0050/eeprom
$ cat /sys/bus/i2c/devices/0-0050/eeprom > eeprom.bin
$ hexdump -C eeprom.bin
