Odd behaviour with TouchGFX 4.17.0

[JMarc.1]

Good afternoon,

I've come across some odd behaviour and wanted to check in with you on it.

I have been developing a project since TouchGFX 4.14 I believe, that I've been running and migrating through the updates without much hassle.

Today, I migrated to 4.17.0, and copied/ pasted a Text Area from one screen to another (I know, my bad !).

This is ultimately the change I found altered the project: I run into Hardfault Handler every time the TouchGFX task starts.

Removing that bit of Text Area "solves" the problem, aka my board boots up, but I end up with either errated colors on my images, or overlapping adjacent screens on/ through my buttons (see pictures). Also the rest of my program does NOT run fine (no comms, no I/O, nothing seems alive - I have yet to determine what is and isn't).

For reference (in simulator, which runs fine in any case):

What could possibly have gone wrong during the migration ?

My project runs on a STM32F769II-DISC0 board. If you need more info I can provide, but not the project files as it is confidential.

Thanks in advance

Hello JMS,

So your problem occured when you migrated from 4.16.1 to 4.17 ?

When migrating a project from one version to the other, you should also migrate the TouchGFX Generator to the same version in CubeMX.

Copy/pasting a TextArea does not seem like a big issue that could ruin your project in my opinion.

When you debug, is it running correctly ?

Artifacts can come from different sources such as the display initialization, the Flash communication, wrong TouchGFX synchronization, etc.

I suggest you compare with the project version that was working to see any discrepancy that seems odd.

Thank you for your reply !

Yes, it occured when migrating from 4.16.0 to 4.17. I did what you told me, migrating everything to the most up-to-date version (CubeMX as well as the TouchGFX Generator, and also CubeIDE just to be sure).

When I debug, it runs correctly now (for some reason) - I have my UARTs, my , albeit one of my screens (the screen where I pasted the TextArea in question) freezes the GUI (while not stopping the other tasks). I haven't figured where the GUI task stops yet.

Thanks again

Hello JMS,

Did you try to see if it works on the simulator ? Removing hardware related code like UART.

Hello, it was running fine in the simulator when I initially posted (you can see the screenshots in my original post).

Today, compiling for simulation fails:
