TouchGFX application is blocking FreeRTOS-Plus-TCP

I have a projet with FreeRTOS and FreeRTOS-Plus-TCP working on a STM32F769I-Eval board.

The ICMP Ping response is 100%.

When enabling a TouchGFX application, even very basic (just a white screen), the ping response rate fall bellow 50%! Not usable at all!

Deactivating the TouchGFX application (comment on the line creating the thread) solve the Ping problem.

Is there a compatibility problem with TouchGFX and ETH on the board?

Or does anybody knows what could explain this behavior?

TouchGFX version 4.21, F7 Firmware v1.17.

Hello @ANauz.1​,

Did you start from scratch (from TouchGFX Designer) or from STM32CubeMX?

It maybe you have an issue with Ethernet/FreeRTOS config! Can you share the settings?

Refer to these posts with Ethernet issues:

Take a look at this video. It might help you.
