MPU configuration when TouchGFX is used

[ToniT]

Hi,

I'm using stm32u599 and an external qspi with touchgfx.
Is it necessary to enable and set the MPU configuration?

Hello @ToniT ,

It depends on the project you are working on, if you think it benefits the performance of your application, then you can enable it. However, you don't need to enable the MPU for TouchGFX project to work on.

You can get inspiration from the STM32U5A9DK Board Setup that is available in the TouchGFX designer for configuring your board.

I hope this answers your question.

Don't hesitate to ask more questions if you have, but remember to follow the guidelines pointed out by our amazing friend @SofLit

Hi,

maybe I asked the question too simply
I already have a working project with several screens in a real device
I read in some application notes that the mpu is mandatory, but they talked about cortex M7 not M33
I had doubts whether it should also be activated for the M33

 

Thanks for you reply.

Oh, I see.

Yes, for Cortex-M7, you need it enabled, and I'm glad that you already have your application up and running.

Good luck!
