Weston Touch Calibration DPI-1 not found apalis imx8 and HDMI resistive touch display

Sry if this is a repeat but none of the other topics similar to this have helped me out. I am new to Torizon and coming from a windows embedded compact 7 environment, so i will probably use the wrong terms at some point. I am using a Ixora carrier board for evaluating and I have a HDMI panel with a resistive touch screen. the touch works but it is off. when I attempt to run the Weston Touch calibrator I get the following:

weston-touch-calibrator error: “DPI-1” was not found.

from what I can see DPI-1 is found as HDMI-A-1 with the correct resolution. I am following the web examples to get this far. when I try to start the weston compositor and install the libdrm-test packages I don’t get anywhere and I am sure I am missing something due to my inexperience with this setup.

Hey @Lon,

Can you give us a bit more about your setup?

What specific Apalis Imx8 are you using and carrier board?
Are you using TorizonCore 5 or 6?
What screen are you using? Is this one of our supplied ones? If a custom screen, have you updated your device tree to reflect this screen?

Here is a similar issue that you can also read through it may help.

Apalis iMX8 QuadMax 4GB, Ixora Carrier board 1.3A, Elo Touch 17 resistive touch 1280x1024 screen on torizon 6.0.3. I am still figuring all of this out. I haven’t even made it into the device tree. I was just getting into the TorizoCore builder and ran into issues trying to unpack it. I am using windows 10 and wsl2 with visual studio Code.

from what I can see in the weston touch calibrator it is detecting the display and touch drivers correctly. that is what has me stumped.

Like I said I am just starting to learn how to use this setup from WEC7. I have been able to create a few code projects and run demos. but now I need to start going a deeper.

Hey @Lon,

It looks like the calibration container startup script is defaulting to a DPI-1 connector (as you stated) and you are wanting this to be HDMI. Here is a write up on this specific issue. You can also follow the suggestion of using a package libdrm-tests inside a container to find your specific head unit name.

-Eric

@Eric,
that is the section I was going through. I have not been able to successfully run the libdrm-test yet. so far I seem to hit a dead end no matter what I try to do. it feels like the documentation is just missing in spots for anything 6.0. I am also trying to get the torizoncore-builder to unpack but that that is a whole other issue.

I will try going through that section again. but if I have to make changes to the device tree that is out of the question until I can get that to work.

6

@Lon,

Ok let me know what blockers you get to with the libdrm-test.

If you would like to open a separate ticket for torizoncore-builder unpack, we can address that as well. For clarity sake we like to keep one issue per ticket.

-Eric

ok when I go through the steps to launch the docker file I get this:

I am sure I am missing something and that is just due to the newness of this .

ok Mangaged to get libdrm-tests to run. not sure how but it ran.

Connectors:
id      encoder status          name            size (mm)       modes   encoders
148     147     connected       HDMI-A-1        340x270         14      147
  modes:

so following the documentation I found the connector information. but what I do after this is unclear.

9

Hey @Lon,

Good to see the progress.

There is a section under the Touch screen calibration link. It gives an example of modifying the connector to LVDS-1 in the run command. HEAD=LVDS-1 , whereLVDS-1 would change to your connector.

docker run -ti --rm -e ACCEPT_FSL_EULA=1 -e HEAD=LVDS-1 --privileged -v /dev:/dev -v /run/udev/:/run/udev/ -v /etc/udev/rules.d:/etc/udev/rules.d torizon/weston-touch-calibrator:$CT_TAG_WESTON_TOUCH_CALIBRATOR

I thought you might mention that. when i try it it won’t find HDMI-A-1 unfortunatly.

@Lon,

Thanks for posting the output. It looks like the container is registering the new connector, but when it attempts to launch the shell it cannot find HDMI-A-1. Can you verify your weston.ini file information? You should have some aspect of :

[output]
name=HDMI-A-1

Here is a bit more information on weston.ini file If you do not have this file already made you may need to create the directory and file.

-Eric

12

ok. forgive my ignorance but I am still in the learning phase of all this docker and container fun.

so the weston.ini file I need to look for it the one in the container for the touch screen calibration?

if so there is no output section there.

[core]
idle-time=0
require-input=false
xwayland=true

[libinput]
touchscreen_calibrator=true
calibration_helper=/usr/bin/save-calibration.sh

[shell]
panel-position=top
locking=false
allow-zap=true
num-workspaces=1

if it is somewhere else. then I will have to stop here and attempt to get the torizoncore builder going first I think.

13

@lon,

You would add the [output] section manually.

[core]
idle-time=0
require-input=false
xwayland=true

[libinput]
touchscreen_calibrator=true
calibration_helper=/usr/bin/save-calibration.sh

[shell]
panel-position=top
locking=false
allow-zap=true
num-workspaces=1

[output]
name=HDMI-A-1

-Eric

alright. I start the weston touch calibration container. I can then edit the weston.ini through the individual containers in VS code. but the changes do not appear to be persistent after I terminate and restart. I am sure this is all just a knowledge issue. that is why I thought I may need to get the torzoncore-builder working to make a new container. I appologize that this is going on as long as it is. so far I have the application software development side of things going. it is just the hardware and container parts that are throwing me off.

15

Hey @Lon,

Thats good that it working. And no need to apologies, part of the Toradex experience is getting software support. It’s what we do!

You are correct that it is not persistent. So we need to be able to save these configurations. Now would probably be the time to get TorizonCore builder working, because that is our recommend method of saving the changing. This information is under the same link with “Development and Production>”

-Eric

16

Well good news is I tried a different HDMI display with a capacitive touch screen and that works. but normally you don’t need to calibrate those guys. so now I am not sure it has to do with the HDMI display.

17

OK I have done a get on the device trees and linux for torizon 6.3 not sure where those folders should go in relation to tcbdir so they are currently in that folder along with the images folder. I have the sample generated tcbuild.yaml file. so the question is what do I need to do select or make changes to the correct device tree?

~/tcbdir$ ls
Apalis-iMX8_Reference-Minimal-Image-Tezi_6.3.0+build.7.tar
device-trees
images
linux
tcb-env-setup.sh
tcbuild.yaml
torizon-core-docker-apalis-imx8-Tezi_6.3.0+build.4.tar
torizon-core-docker-apalis-imx8-Tezi_6.3.0+build.4.tar:Zone.Identifier
powis@DESKTOP-NMD62I2:~/tcbdir$

Hey @Lon,

Would you mind starting a new ticket for the new question? It helps when people search for solutions for old posts.
But to get you started. A typical project might look something like this:

image

with a custom device tree overlay file located in : device-trees/overlays/my-custom-device-tree.dts

and it gets referenced in the tcbuild.yaml file:

image

This document is a great reference for work-flow:

ok I will start a new one. but real quick when you use the torizoncore-builder unpack command. where does the output of that goto? I have yet to see any folders anywhere when I run it.

20

Hey @Lon,

You won’t see the results of unpack command in the root folder, it’s going to be held in a docker volume.
