[meta-fsl-arm] QT5 on SabreLite

[meta-fsl-arm] QT5 on SabreLite

[Gary Thomas]

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.

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?

was that with the same rootfs ?
Did you calibrate again after flashing this one ?

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)

No, separate SD cards, one for each flavour.

Yes, no change.

Hi,

Maybe try different device (e.g. /dev/input/event0). AFAIR it should be
like this for example:

... -plugin tslib:/dev/input/event0

or instead of adding this as command line argument it can be set as
environment variable:

export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0

Best regards,
Filip

dora 3.10.9 w/fsl-image-gui?

[randy.krakora]

[-- Attachment #1: Type: text/plain, Size: 162 bytes --]

Using the dora branch, 3.10.9-1.0.0_alpha with core-image-minimal, seems to boot fine fsl-image-gui hangs then crashes.

Any ideas?

Regards,
Randy Krakora

Try doing the following in U-boot prompt:

=> setenv fdt_file imx6q-sabresd-ldo.dtb
=> save
=> reset

If this does not solve, please paste the full log.

Yes, that fixed it, thanks.  I used tslib:/dev/input/touchscreen0
