I gave up on the 4.3" LCD. It had to many issues (and the screen resolution
is not large enough for what I need). I'm now trying a 7" screen,
specifically
the 4DCAPE-70T.
That screen works great with the latest Debian image:
$ cat /etc/dogtag
BeagleBoard.org Debian Image 2018-01-01
The board boots to the LXQt desktop and after calibration the touch screen
works fine.
I'm still having issues getting a Qt app to work. I tried Qt5 first with
this simple
test code:
#include <QApplication>
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
return app.exec();
}
With Qt5, when I try to run the test app I get:
libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate
So I then tried Qt4. With Qt4 the test app doesn't do anything. It just
hangs
until I kill it.
I'm not sure where to go from here. Even if I get it working I still need to
figure out how to get Qt to work from the console with no X server
installed.
Any help would be appreciated.
Thanks,
Hartley
