Current porting status

  • Mainline boots and has touch, screen, and side keys working.
  • All 4 cores are now up!
  • NFC available!
  • USB is currently being tested, I can't personally confirm if USB networking is working but someone with a Lumia 735 said it is for them.
  • Proximity is working on tesla, just needs testing on dempsey
  • WLAN & BT being looked at

Guides (Should work in theory for the other Lumia's specified in the EDK2 port as well.)

Here's a nice guide written by WolfLink115 which explains how to compile/install EDK2 and boot Linux:

  • [1] Compiling EDK2
  • [2] Installing EDK2
  • [3] Booting Linux from eMMC
  • [4] If you manage to brick the Lumia 640 (the RM-1073 version, not tested on others!!) into Qualcomm EDL mode, then this guide can help you unbrick it.

  • [5] Close to mainline linux kernel w/ support for dempsey and a few other msm8x26 lumias on msm8x26 branch. Use msm8x26-touchscreen branch for touchscreen, until it gets committed into msm8x26.
  • [6] EDK2 for dempsey, tesla, makepeace and superman. This does boot Linux!
  • [7] LittleKernel for tesla and some other lumias. This does not boot Linux!! Useful for chain loading lk2nd to dump regulators when porting a lumia to linux.
  • [8] Boot shim used to boot EDK2.
