So, it has been nearly two days I struggle with these issues. Here is where I am now and what I’d like to achieve.
I followed step by step this tutorial to build my own boot to Qt Linux embedded image: Building Your Own Embedded Linux Image | Qt 5.15.5 for Device Creation
Next I installed it on my iMX6DL with the help of toradex easy installer via an SD card plugged in my aster carrier board.
I also built the toolchain and so far I am able to run any Qt app on my 7" capacitive touch display.
and here starts my problems… despite all my efforts I simply cannot make my touch pannel to work. I know that my pannel works because I managed to use it on easy installer using the “boot.scr” file as explained here: Toradex Easy Installer
I also followed every steps here:
Except for “Change the device tree according to the patch below”
Since I simply don’t know how to do it and every research I did on the toradex forum or yocto forum did not help at all…
It is always said to go to arch/arm/boot… but I can’t find it anywhere precise on my yocto environnement (There are like dozens of these directories)
So my query would be a simple step by step tutorial on how to easily patch my device tree using yocto (since I used it with the Qt tutorial) and then recompile everithing so I can reflash it to my SD card and then to my colibri board.
Please understand that I have never used yocto or bitbake before but I also need some good advice about it because I am gonna work on this for nearly the next 6 months.
Edit: Is it possible to patch the device tree with the help of a meta-layer? For instance could someone provides me a *.bb file?
PS: here is a log file containing dmesg link text
And here are a small list of all the cmd I ran in U-Boot and as root link text
I really hope someone can help me!
