I finally got QT5 to build for my i.MX6Q SabreLite. I'm able
to run the cinematic demo, but the touch screen isn't working.
Here's what I get:
root@sabrelite:~# Qt5_CinematicExperience -platform eglfs -plugin tslib
evdevtouch: Using device /dev/input/event1
min X: 0 max X: 0
min Y: 0 max Y: 0
min pressure: 0 max pressure: 4095
device name: tsc2004
EGLFS: Unable to query physical screen size, defaulting to 100 dpi.
EGLFS: To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and
QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
QTsLibMouseHandler "tslib" ""
Protocol type A
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
Notice that the touch window is 0x0. I know the touch is set up
properly and calibrated as I've run the ts_* programs as well as
X11 and QT4.
was that with the same rootfs ?
No, separate SD cards, one for each flavour.
Did you calibrate again after flashing this one ?
Yes, no change.
How do I get the touch screen working with QT5?
BTW, the demo reports being able to display a screaming 177FPS!
Does that make sense?
that's what I also got and put in the comit message :
commit f8852824e6944943480f685d498ccce4ffec2c30
Date: Mon Oct 7 15:37:29 2013 +0000
qtbase: update mx5 & mx6 support
- remove 5.0.2 as meta-qt5 has 5.1.0 by default
- tested on i.MX53 with eglfs and xcb platforms. FPS is not very
good despite the GPU (~24 fps on 800x480)
- tested on i.MX6 with eglfs platform : performance is very good
(> 150 fps on 640x480)
