New image with support for PiTFT touchscreen

[Chris Jones]

If you own one of these extension boards

https://www.adafruit.com/products/1601

then you can start using it with FFOS on RPi as of the latest image posted
to

https://wiki.mozilla.org/Hacking_b2g_on_Raspberry_Pi#Flash_an_existing_build

Follow the instructions immediately below

https://wiki.mozilla.org/Hacking_b2g_on_Raspberry_Pi#Enable_touchscreen_output

to enable/disable PiTFT output. Enjoy!

Cheers,

Hey,

That's cool! There are very few RPi compatible displays in the market. I
had my eyes set on 10" LCD LVDS bundle with capacitive touchscreen
for Raspberry Pi from chalk- <http://chalk-elec.com/>elec.
<http://chalk-elec.com/>com <http://chalk-elec.com/>
.
What does it take to support more generic touch devices to work with FxOS
raspberry pi builds.

Cheers

Arky

The gonk/android layer we're building on assumes a mostly static HW
configuration (unlike "desktop linux", or Raspbian), so unfortunately it's
a bit hard. I put together a hack in

https://github.com/mozilla-b2g/device-rpi/blob/master/b2g.sh#L11

that could be extended out relatively easily ... but not prettily ;). The
first step is to find drivers for the touchscreen that are compatible with
the Raspberry Pi's kernel.

Cheers,

​I should also warn that you high-resolution displays will perform badly
with the current FFOS builds for RPi. We didn't get the Broadcom
accelerated graphics stack debugged in time. You may want to wait a while
before trying them, unless you're very patient ;).
