What works

  • Compiling the kernel
  • Building a base image
  • Fastboot flash
  • SD card install
  • Modules and firmware installation (sort of)

Current Build / Boot Process

Build and install to SD card:

$ ./pmbootstrap.py install --sdcard /dev/mmcblkX

Boot the phone into fastboot mode (power + volume down) and flash the boot partition:

$ ./pmbootstrap.py flasher flash_kernel

Insert SD card and boot.

Known Issues

Modules / Firmware Support

Most modules and firmware while built and installed do not load correctly. Ongoing work is in progress to support:

  • Touchscreen
  • Wifi
  • Audio
  • etc.

Unknown chunk type

mozilla-flame.img cannot be flashed to either the system/userdata partitions due to bootloader limitations (probably because the system image is larger than the max download size and it forces the download into sparse mode, which is handled badly.)

$ fastboot flash userdata flame/mozilla-flame.img 
target reported max download size of 301989888 bytes
erasing 'userdata'...
OKAY [  1.254s]

OKAY [ 10.018s]

FAILED (remote: Unknown chunk type)
finished. total time: 11.275s

Workaround is to install to SD card, or to init your build with none UI instead of weston, which will produce a system image under the limitation.
