Re: [beagleboard] Qt 5.4 on BBB OpenGL: Linux is dead after execute examples. Keyboard and mouse have no response.

2014-12-13 Thread Yang Lei

Thanks!

I tried adding -platform eglfs but the result is still the same. Either
mouse and keyboard doesn't response.

I believe the default platform is eglfs. So, even I don't use -platform
option, the it should run with eglfs platform. Am I right? My reference is
here http://doc.qt.io/qt-5/embedded-linux.html.

Any more suggestion?

Re: [beagleboard] Qt 5.4 on BBB OpenGL: Linux is dead after execute examples. Keyboard and mouse have no response.

2014-12-14 Thread liyaoshi

As I know , Ti's Graphic driver will not support 3.18 kernel for current
now
You should use 3.12 to match the ti graphic driver

Thank you for the respond. However, I've successfully run the Graphic's
demo program on 3.18 kernel. Does that mean the Graphic driver has no
problem? Thanks!

Re: [beagleboard] Qt 5.4 on BBB OpenGL: Linux is dead after execute examples. Keyboard and mouse have no response.

You should "re-read" the thread.  You'll find even Arch Linux ARM
can't solve this, as you'd still have to "manually" rebuild qt5 with
the un-distributable sgx lib bits.

Sorry Arch isn't always the answer..

Sounds like you don't have permission to the input devices.
Try running with sudo or add the keyboard / mouse to a group and add 
permissions to your user.
LinuxFB and eglfs require direct access to /dev/input/event?

Hello Peter,

Thank you for your response. After I tried running with sudo, the keyboard
and mouse work, now!
Also, I created /etc/udev/rules.d/99-input.rules with following content:

KERNEL=="event*", NAME="input/%k", MODE="664", GROUP="input"

Then, I rebooted BBB and all the events have read permissions. The qt
example programs works.

By the way, I noticed another problem. When the Qt programs are running,
the terminal's cursor is still flashing. Sometimes the whole terminal
screen will pop-up for a very short time. So the whole screen is flashing.
I think this is because the terminal is trying to refresh the screen. How
can I stop terminal from refreshing the screen? Thanks!

(Should I start this problem in another thread?)

You can turn off the cursor using environment variable QT_QPA_EGLFS_HIDECURSOR=1

I haven't found the proper way to have the console and a EGLFS Qt application 
on the LCD work at the same time.
I've found that debugging messages go to the main console while the Qt 
application runs on the LCD
So, the LCD display flashes with debugging messages on the console.
I had to re-compile Qt 5.3 with -DQT_NO_DEBUG_OUTPUT -DQT_NO_WARNING_OUTPUT to 
get it to stop spamming the main console.
If you figure out how to make it work right, that would be great.

A great resource for Qt embedded options is here:

I think you just remove the console=tty0 from your mmcargs line in
uEnv.txt file. That should remove the console output from your display,
but will continue to display the console on the UART.
