Graphic subsystem randomly crashes, requiring an hard reboot. {{issue|424|pmaports}}
 +
 
 +
==== Power Management ====
  
==== WiFi workaround on boot ====
+
At this stage the directory <code>/sys/devices/system/cpu/cpufreq</code> is empty, so it seems there is no integrated power management.
The wifi adapter works in NetworkManager, but it boots in airplane mode and NetworkManager does not detect that. Therefore at boot you need to disable the wifi adapter first, and then re-enable it. This can easily be done in the graphic shell (Plasma Mobile has an airplane mode switch in the pull-down menu: check it and uncheck it) or through the shell:
+
 
 +
There is also no way to turn off touch detection or turning off the screen through a button.
 +
 
 +
Still, you can
 +
 
 +
<pre class="shell">
 +
# Turn off screen
 +
    echo 0 > /sys/class/backlight/lcd-backlight/brightness
 +
# Turn on screen
 +
    echo 250 > /sys/class/backlight/lcd-backlight/brightness
 +
 
 +
# Turn off screen and suspend (deepsleep?)
 +
    sudo su -c "echo 0 > /sys/class/backlight/lcd-backlight/brightness" && exec pm-suspend
 +
 
 +
#disable two cores (not sure if temperature decreases)

 +
 
 +
==== Audio ====
 +
 
 +
No one has still worked on playback and recording support.
 +
 
 +
Neverthless you can use another device (like an android device) to stream your audio.

</source>
 +
 
 +
Don't forget to copy cookie (<code>~/.config/pulse/cookie</code>) to from sink to source!
 +
 
 +
==== Bluetooth ====
 +
 
 +
Bluetooth seems to work somewhat. Power and scan functions in bluetoothctl work but pairing might not.
 +
 
 +
To test, use instructions at https://wiki.alpinelinux.org/wiki/Raspberry_Pi_3_-_Setting_Up_Bluetooth.
 +
 
 +
==== Cellular modem ====
 +
 
 +
Using instructions at https://wiki.postmarketos.org/wiki/Nokia_N900_(nokia-n900)#SMS it seems that SMS and calls likely work.
 +
 
 +
==== WiFi====
 +
On Phosh session wifi adapter currently starts.
 +
 
 +
Before, the wifi adapter started in airplane mode and NetworkManager did not detect that. A manual workaround is to disable and re-enable the wifi adapter.  
 +
 
 +
This can easily be done in the graphic shell (Plasma Mobile has an airplane mode switch in the pull-down menu: check it and uncheck it) or through the shell:

==== Webbrowser ====

In plasma-mobile, Angelfish webbrowser does not run. You may want to install and use qtwebbrowser, which runs and is kind of usable despite the fact that it still has some crashes happening.

 +
=== Software issues ===
 +
 
 +
==== Phosh ====
 +
 
 +
If the screen gets locked, since default passcode is unknown you can't go back.
 +
 
 +
Pressing power button will "block" the screen, keeping it turned on with touchscreen working.
 +
 
 +
If the interface hangs, restarting LightDM with <code>sudo rc-service lightdm restart</code> has no effect and you have to force reboot. {{issue|540|pmaports}}
 +
 
 +
'''Browsing'''
 +
 
 +
- Epiphany works well, but doesn't load youtube videos and tends to crash after a while;
 +
 
 +
- Chromium crashes;
 +
 
 +
- Firefox works but crashes after a while;
 +
 
 +
- Qutebrowser works well but crashes after a while;
 +
 
 +
- Vimb works but crashes after a while;
 +
 
 +
- Netsurf never crashed.
 +
 
 +
- Dillo will probably work, too.
 +
 
 +
==== Plasma Mobile ====
 +
[https://invent.kde.org/jbbgameich/plasma-angelfish Plasma Angelfish] does not run. You may want to install another browser, like qtwebbrowser, [[Firefox]] and/or [[Chromium]].
 +
 
 +
=== Troubleshooting ===
 +
==== Fastboot unknown chunk type ====
 +
Flashing with fastboot seems to fail for some outdated firmware, it prints the message "FAILED (remote: Unknown chunk type)" when trying to flash the rootfs to userdata.
 +
This can be solved by updating to the [https://developers.google.com/android/images#hammerhead latest baseband firmware and bootloader].
 +
 
 +
==== Remote Data Too Large ====
 +
Sometimes `./pmbootstrap.py flasher flash_kernel` can fail with an error message that includes "Failed (remote: data too large)".  This might be solved by updating by reflashing [https://developers.google.com/android/images#hammerhead the latest version of the stock Android image for the device].

Fastboot Mode

First make sure to enable USB debugging in Android ([1]) Then with device powered off, hold down Volume Down and Power buttons simultaneously for a few seconds, until Fastboot Mode screen appears.

OEM Unlock

Get device into Fastboot Mode, plug in USB cable, then:

$ sudo fastboot oem unlock

When prompted on device, use Volume-Up/Down buttons to highlight choice, then Power button to select it. The Fastboot Mode screen will appear again, and a message regarding flashing will appear briefly.

Installation

First build the image:

$ pmbootstrap init
$ pmbootstrap install

Then in order to flash it put your device in fastboot mode, and plug it in USB. Then do:

$ pmbootstrap flasher flash_rootfs --partition userdata
$ sudo fastboot format system
$ pmbootstrap flasher flash_kernel

Hardware issues

Graphic subsystem randomly crashes, requiring an hard reboot. pmaports#424

Power Management

At this stage the directory /sys/devices/system/cpu/cpufreq is empty, so it seems there is no integrated power management.

There is also no way to turn off touch detection or turning off the screen through a button.

Still, you can

# Turn off screen
    echo 0 > /sys/class/backlight/lcd-backlight/brightness
# Turn on screen
    echo 250 > /sys/class/backlight/lcd-backlight/brightness

# Turn off screen and suspend (deepsleep?)
    sudo su -c "echo 0 > /sys/class/backlight/lcd-backlight/brightness" && exec pm-suspend

#disable two cores (not sure if temperature decreases)
    echo 0 > /sys/devices/system/cpu/cpu{2..3}/online

Audio

No one has still worked on playback and recording support.

Neverthless you can use another device (like an android device) to stream your audio.

source device

# /etc/profile
  export PULSE_SERVER=<sink_device_ip_address>

sink Device

# etc/pulse/default.pa
  load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1

Don't forget to copy cookie (~/.config/pulse/cookie) to from sink to source!

Bluetooth

Bluetooth seems to work somewhat. Power and scan functions in bluetoothctl work but pairing might not.

To test, use instructions at https://wiki.alpinelinux.org/wiki/Raspberry_Pi_3_-_Setting_Up_Bluetooth.

Cellular modem

Using instructions at https://wiki.postmarketos.org/wiki/Nokia_N900_(nokia-n900)#SMS it seems that SMS and calls likely work.

WiFi

On Phosh session wifi adapter currently starts.

Before, the wifi adapter started in airplane mode and NetworkManager did not detect that. A manual workaround is to disable and re-enable the wifi adapter.

This can easily be done in the graphic shell (Plasma Mobile has an airplane mode switch in the pull-down menu: check it and uncheck it) or through the shell:

$ sudo nmcli radio all off
$ sudo nmcli radio all on

Software issues

Phosh

If the screen gets locked, since default passcode is unknown you can't go back.

Pressing power button will "block" the screen, keeping it turned on with touchscreen working.

If the interface hangs, restarting LightDM with sudo rc-service lightdm restart has no effect and you have to force reboot. pmaports#540

Browsing

- Epiphany works well, but doesn't load youtube videos and tends to crash after a while;

- Chromium crashes;

- Firefox works but crashes after a while;

- Qutebrowser works well but crashes after a while;

- Vimb works but crashes after a while;

- Netsurf never crashed.

- Dillo will probably work, too.

Plasma Mobile

Plasma Angelfish does not run. You may want to install another browser, like qtwebbrowser, Firefox and/or Chromium.

Troubleshooting

Fastboot unknown chunk type

Flashing with fastboot seems to fail for some outdated firmware, it prints the message "FAILED (remote: Unknown chunk type)" when trying to flash the rootfs to userdata. This can be solved by updating to the latest baseband firmware and bootloader.

Remote Data Too Large

Sometimes `./pmbootstrap.py flasher flash_kernel` can fail with an error message that includes "Failed (remote: data too large)". This might be solved by updating by reflashing the latest version of the stock Android image for the device.
