An overview of the project state:

I am working porting Firefox OS to the Raspberry PI B+ 2. It's a 6 months project starting from November 2015.

Possible Blockers:

- Raspberry PI B+ 2 uses a chipset from Broadcom that is not fully open source. Current sources implementations are good but still needs work.
- Raspberry PI B+ 2 uses a video driver named VC4. It's implemented only in this new model. Current source implementation is good but it works slow rendering. (best slow than no implementation)

FAQ (?):

- Why model B+ 2?
Because, is the newest version at this moment of the Raspberry Pi and the model with high specs compared to other versions/models.

- Would this port work on B+ (not 2)?
No, B+ and B+ 2 have a different chipset that make sources (like kernel/board configuration) incompatible. Right now the focus is the model B+ 2, would be possible consider working on past models/version, but not a goal for this project right now.

Today was the first successfully build using B2G build system. I removed VC4 sources/support for now. The first batch of build will be have a generic EGL driver.

Working on build the rpi kernel from source.

** About this build **

This is the first build that boots without crash b2g and with VC4 driver included. The mesa lib needs a lot of work, right now it shows everything in yellow color. Gecko, Gonk and Gaia are running good (as expected)

Development Sprints and Flashing steps updated:

https://wiki.mozilla.org/FirefoxOS/RPiB2

Wiki should be helpful to reproduce and flash builds with the steps there after repos are landed officially.

Most of the repos are landed and merged. Bug 1233991 is going to be merged at the end.
