4 questions about "st-example-image-qt"

[IYetk]

Hello,

I have 4 questions if you have time to answer, I would appreciate it very much.

1. I prepared st-example-image-qt image. But there isnt any terminal like weston image. Should I run any other command before bitbake in order to have all the tools packages and freameworks that weston image has ?
2. If you can, could you please write me all commands that I should run to prepare such a full featured -qt image ?
3. How can I run an example in this image ?
4. Can one do following things with this image ?

• modify, rebuild and run an example with opensourse qt license ?
• write a qt app from scratch with crosstoolchain in ubuntu laptop with open source qt license and load it to the dk2-board ?

thanks in advance

Based on my experience, there are multiple issues with st-example-image-qt. Hence my question in this forum. Hope someone more knowledgeable will be able to answer it.

Hi @IYetk​ 

The st-example-image-qt is provided with many samples code all in /usr/share/examples

You need to do :

root@stm32mp1:~# psplash-drm-quit

root@stm32mp1:~# export QT_QPA_EGLFS_ALWAYS_SET_MODE="1"

Prior to execute them to release DRM KMS resources.

I will try to come back with few hints for other points but please be aware of the following ST support strategy for QT image :

The OpenSTLinux distribution offers the possibility to use an example of an image based on the QT framework (st-example-image-qt) as a demonstrator, not for developing products. For Qt-based products, the list of STMicroelectronics partners can be found on STMicroelectronics web site.
