[yocto-rocko] : fsl-community-bsp X11 build touch screen calibration issue on iMX6UL

Hello,

 

I have been working on Rocko build from fsl-community-bsp, since last few
days and able to complete the builds for our various devices which uses
imx6UL and imx6Solo processors.

 

During testing these builds, I have encountered few issues and also could
able to solve some of them. 

 

I need your help in one of issue where I am still unable to get the
resolution. Please see details as below

 

Machine: imx6ulevek

Image: core-image-x11

 

The issue I have observed on the device is, Xorg is unable to calibrate the
touchscreen, I don't know what has changed but it is unable to calibrate,
below is the log I get on prompt

 

 

Using calibration data stored in /etc/pointercal.xinput

Invalid format 42060

unable to find device EETI eGalax Touch Screen

matchbox: ignoring key shortcut XF86Start=!matchbox-remote -desktop

 

INFO: width=480, height=272

ERROR: XorgPrint Calibrator does not support the supplied --output-type

Error: unable to apply or save configuration values

 

Actually I have seen this issue first on our machine conf file and build
recipe, but just to confirm I have built imx6ulevk machine and see the same
issue.

 

I am not using eGalax EETI Touch screen, it should use iMX6UL's internal
touchscreen controller, i am using simple resistive touch screen. Basic
touch screen is working, because when during first power up when X tries to
calibrate the touch screen, it is able to detect every touch but when it
tries to write to /etc/pointercal.xinput it says output type is not
supported, and if i look at xinput_calibrator_once.sh in /usr/bin which is
called at first power up the --output-type is defined as xinput which is
correct. So as it is not able to save the calibration points the touch
screen doesn't work in X or in any of QT apps we are building.

 

I believe this is nothing do to with kernel as i am using 4.1.35 which was
in morty build and where this touch calibrate is working well. i just bumped
the version of all apps/rootfs to rocko so as to get all latest application
versions like QT-5.9.7 etc, so i think there is something changed in X build
and which is broken.

 

Can somebody please help.

 

Thanks

 

 

Kind Regards,

Does not installing xf86-input-libinput help? xinput-calibrator cannot cope with that input backend.

I used the following bbappend to achieve this:

Hi Max,

 

Yes you are right, I used the same bbappend and this resolved the issue, perfect solution…

 

I have been struggling with this since couple of days! 

 

Many thanks for your inputs and resolution.

 

I have tested the build for imx6ulevk as well as to our own machine, both worked well. Calibration passes correctly and also writes it to /etc/pointercal.xinput file and works perfect

 

Thanks once again…

 

Regards

Alankar
