We need details about TouchGFX`s use of the crc module

[Alex K.]

Since version 4.10 TouchGFX needs the crc clock enabled to check if it runs on a STM32 MCU.

This worked fine for us so far.

Now we are adding other functionality to the application that require the use of the HW-CRC module.

Depending on how we configure the CRC module, we seem to run into some hardfault from within the TouchGFX initialization.

Please give us some information what TouchGFX will need to run.

Will TouchGFX do its checks only once or repeatedly?

Hi @AK.12.​,

Any updates on your end on this issue?

Hi @Martin KJELDSEN​ ,

i think we are through this at least for the moment.

There was a problem with our FreeRTOS Stack Sizes.

Can´t check often enough that Task size is in words and the FreeRTOS config is in bytes....

Some of our other tasks were growing fast, not instatiating the GUI Task helped, because it already had a big size.

So, issue solved.

Thanks again.

Haha, i hear you about the words vs bytes size "issue" :)

Glad you've moved on.
