Intermittent weird text area

Muharrem · ‎2025-02-20

Hello.

I try develop TouchGFX+FreeRTOS based project for my custom board.

I have a text area problem. I attached photo. Also project attached.

It is not stable. It looks like always updating.

Also when i touch the buttons other text areas looks same just for a moment then stay stable.

What may cause to this problem?

I try to solve it via typography, task priority, but no result.

Microcontroller:STM32F750

CubeIDE ver: 1.15.1

TouchGFXDesigner: 4.24.0

Thanks.

I disabled "DCache" and it works stable now.

It says: "It is recommended to disable at least the data cache until you have a stable platform."

"The solution is to flush the cache at certain points in your project, but we recommend to deal with this at a later point."

The solution doesn't look like easy. Disabling the Dcache is best solution for me.

Which problems may occur if i disable the Dcache?
