== What works ==
* Screen
* Audio* (more information below)
* USB Network
* Wifi*
* Touch (/dev/input/event4)
* Proximity sensor (/dev/input/event0)
** enable with echo 1 > /sys/class/input/input0/enable
* Accelerometer (/dev/input/event1)
** enable with echo 1 > /sys/class/input/input1/enable
* Compass (/dev/input/event2)
** enable with echo 1 > /sys/class/input/input2/enable
== What does not work ==
* Setting up wifi using NetworkManager GUI/applet. (nm-applet never asks for the PSK, manually setting the password works and nmtui works too)
* Everything else
== Audio ==
Audio works partially and only with Alsa. PulseAudio doesn't seem to work even when changing the sample rate to 48KHz.
* Playback only work with with the sample rate of 48KHz. Anything else than 48KHz results in silence or or crackling (and the logs say "underrun!!!")
* Recording works only with the sample rate of 48KHz and mono only.
Alsa record & playback test:
arecord -f dat -c 1 | aplay -f S16_LE -r 48000 -c 1

* Both 150kΩ and 619kΩ resistors work for a serial debug cable.
== Bootloader / S-Boot 4.0 ==
To abort auto-boot, press Enter while the phone is powered on. You will need a serial debug cable to be connected before powering on.
Use command help to get started and use command log to print the output log if commands don't print output immediately.
More instructions about the log level and debug printing can be found below.
