Raspberry Pi Official touchscreen (+Dual Display) support on GDP11 image

Thanks Friedrich

I already had a look to it to mailing list discussion (enivi-ivi-layer-management at lists.genivi.org<mailto:enivi-ivi-layer-management at lists.genivi.org> &  genivi-projects at lists.genivi.org<mailto:genivi-projects at lists.genivi.org>) to support the multi display support

I want to avoid any baseline recompilation.

So Based on GDP11 image (official release for RPI2 gdp-11-rpi.sdimg.gz<http://docs.projects.genivi.org/gdp_files/v11/GDP11/raspberrypi2/gdp-11-rpi.sdimg.gz>),
I have simply modified /etc/xdg/weston/weston.ini

To add output for RPI touchscreen
#HDMI
[output]
name=HDMI1
mode=1920x1080

#Touchscreen
[output]
name=LVDS1 (or name=DSI1 ?)
mode=800x480

and relaunch weston with drm as backend
weston  --backend=drm-backend.so --tty=2

but I still see only one screen on LayerControlManager
LayerManagerControl get screens
1 Screen(s):
- Screen 0 (0x0)

So clearly one modification is missing, probably during boottime to load the touchscreen driver
Do you have an idea ?
Or do I really need to get and recompile the main baseline (and make menuconfig to force DSI touchscreen loading) to get the 2 screens

Thanks in advance

Regards

Jocelyn

Subject: Raspberry Pi Official touchscreen (+Dual Display) support on GDP11 image

Hello

I am new with genivi (working as SW architect at Renault)

I currently wanted to test the weston IVI shell dual display feature on PI2 (HDMI + RPI2/RPI3 Official touchscreen)

Currently I just wanted to get the GDP11 RPI2 official image (currently only GDP11RC1 image available) and modify the Weston.ini and Weston backend accordingly to activate the 2 outputs

My questions are :

-          Is Raspberry Pi Official touchscreen currently integrated on GDP11RC1 ? planned for GDP11 ? or only available on Main (as mentioned by GDP-206<https://at.projects.genivi.org/jira/browse/GDP-206>)

-          Condidering  Raspberry Pi Official touchscreen driver integrated on GDP11, what are the exact steps to activated the 2 displays simultaneously ? (only Weston.ini modifications necessary + Weston reloading with DRM backend) ?

Regards


Jocelyn Leheup
