How to enter flash mode

  1. Turn off the device
  2. Press Power + Volume Down to enter fastboot

Installation

Here's how to boot pmOS via fastboot:

  1. Install to a SD card with

$ pmbootstrap install --sdcard=/dev/sdX

  1. Insert the SD card into the device
  2. Connect the device to your PC
  3. Enter the fastboot mode
  4. Finally, boot pmOS:

$ pmbootstrap flasher boot

or

  1. Enter the fastboot mode
  2. Flash system

$ pmbootstrap flasher flash_system

  1. Flash kernel

$ pmbootstrap flasher flash_kernel

  1. Finally, reboot into pmOS:

$ fastboot reboot

Audio

To enable audio you need to install triggerhappy. You can do it in many ways:

As a flag during PMOS installation:

Follow the standard Installation guide, and during pmbootstrap install step, use --add triggerhappy flag

As a package on running device:

Type in device terminal: $ sudo apk add triggerhappy

Note On both cases you always need to enable the triggerhappy daemon with: $ sudo rc-update add triggerhappy default

FDE

Encryption works fine, but osk-sdl has some issues with pixelformat modes. I recommend to test Unl0kr, because its made on LVGL, so it shouldn't have the same problems that osk-sdl encounters with directfb SDL2 backend.

Note Actually, osk-sdl is working ok(ish) with pixelformat argument set in DFBARGS to ABGR, but I couldn't get this to work in initramfs and I don't think it is a proper way to do this.

Parts

Smart Speaker

To use the speaker, the device relies on:

Vendor Model
Texas Instruments tas2557 (some useful commits 1)

Seems to be very similar to tas2559

Fingerprint

Two drivers are available within downstream kernel

Vendor Model
Fingerprint Cards AB FPC1020 (some useful commits 12)
Goodix GF3208

Sensors

Type Vendor Model
Accelerometer / Gyroscope STMicroelectronics LSM6DS3
Magnetometer / Compass Asahi Kasei AK09918 1
Ambient Light Liteon Opto LTR579 ALSPS
Hall ROHM Semiconductor BU52061NVX

Serial UART

TODO TODO: This section needs further testing

Getting UART output on this device should be pretty straightforward, because pins for serial transfer (TX and RX) are exposed directly on motherboard and are even labeled.
