Hi,
I am new to the AGL project. After reading and trying out some stuff
without success I try to ask here.
My Setup is a Raspberry PI 3b+ with the PICAN2 extension board and the
official 7” touch display.
Further I connect a 1920x1080 display via hdmi.
Likely the pi is not powerful enough to drive 2 screens with different
sets of 3d content.
I want to bring up an AGL image with the HVAC demo app using the CAN
bus to communicate. Further the navigation app should run and and
mimimap, engine speed and so on should be shown on the second screen
like in the video of ces 2017 (https://www.automotivelinux.org/videos) .
The demo uses 2 boards actually. One for the main demo and one for the
engine speed.
I already tired some prebuild binaries like the release 5.1.0 or the
master branch and may more to get a running RPI with 2 screens, but I
always got problems. Sometimes the resolution was wrong (if I fix it
in western.ini everything freeze on start), another time no screen is
shown and the raspberry does not boot.
What is also very interesting for me is: There are only demo
applications. Is there somewhere any clean image without demos, where
I can start to build application by myself?
If you use master, you can try e.g. agl-image-minimal (terminal) and
agl-image-ivi (weston) as a base for own experiments.
Or you create your own image definition similar to agl-demo-platform.bb
and remove some apps.
I think of reimplementing such a demo application with CAN-Bus support
to get a better understanding. I think of something like an image with
just the homescreen without demo apps, just the apps I install manually.
Great idea! That is possible of course. Create your own image recipe for
this.
Best,
Jan-Simon
