  • Daniel071 (Notes: Works great except very poor performance; Probably because of no hardware acceleration)

What works

  • Display
  • Weston
  • Touchscreen
  • USB
  • Wifi (if started up manually, there's still some problems on boot)
  • FDE w/ osk-sdl
  • Battery (Gnome 3 can read the battery percentage, whether it is discharging or charging and Charging-sdl does work. One small issue is that Gnome 3 cannot detect the battery time remaining)

What does not work

  • RIL (hasn't been setup yet, but Replicant got it going on the android side so it should be possible.)
  • 2D + 3D acceleration (so most UIs slow down to a crawl, such as plasma-mobile).
  • Currently the kernel is not mainlined, but the OMAP chip is supported, so it should be possible to mainline.
  • Bluetooth service crashes; Running sudo service bluetooth start and then sudo service bluetooth status returns "crashed"
  • Audio does not work with both built-in speakers and headphone jack (Tested with Gnome 3)

To test/do

  • Audio
  • Graphics Acceleration
  • GPS/Compass/Sensors
  • RIL

How to enter flash mode

Press Power + Volume Up to enter download/odin mode.

Installation

This has to be done in two parts:

  • First create an Android recovery image of PMOS and flash it using TWRP. If it refuses to flash using the "Install" option, try to flash it with adb sideload.
  • Then use the usual heimdall flasher method to install the kernel and initramfs (flash_kernel).

Doing both with one method results in errors in both situations.

Note: If you wish to install to the /data partition instead of the system partition, extract the Android recovery image, replace FACTORYFS with DATAFS in chroot/install_options, and re-archive it with no compression. (zip -0r disiredFileName.zip *)
