[meta-raspberrypi] Adding more screens / PiTFT support.

[-- Attachment #1.1: Type: text/plain, Size: 811 bytes --]

Hi,

I would like to add PiTFT support to the meta-raspberry layer. Or at least I would like to add it in my own BSP layer.
I read that Peter were playing with that recently. Could you please give me some hints to do so?
I have at least two more screens to integrate.

If someone could point me to an example of a BSP based on meta-raspberrypi that would be awesome.

Thanks in advance,
Best Regards

Hi Julien,


After some discussions with the community, we decided that the
official meta-raspberrypi pitft support should be added using
MACHINE_FEATURES. If you look in README for meta-raspberrypi there are
some basic description about how to enable support: 

For a already
supported pitft model (pitft22 is supported and 28r is on it's way
https://lists.yoctoproject.org/pipermail/yocto/2016-March/029284.html),
you can just add below MACHINE_FEATURES to local.conf:


MACHINE_FEATURES += "pitft pitft22" 

In order to add support for
additional models you can use
https://lists.yoctoproject.org/pipermail/yocto/2016-March/029284.html as
a reference.
 Basically what you need are to: 

* add the overlay for
the screen 

* Add dtoverlay option with wanted default arguments in
rpi-config_git.bb 

* Add a default calibration (if needed) 

Assuming
an overlay exists for your model, it shouldn't be so tricky to fix the
rest..

As Petter says, everything should be in the README. Try to give it a
spin and tell us how it goes.
