HI @macrobert 

Please have a look to this page:

https://wiki.st.com/stm32mpu/wiki/Interrupt_overview

My understanding is that you cannot manage interrupt in user space, you need to have a driver going thru irqchip

Qt? For STM32?

OK, I just realized this is for STM32MPxx; that's a very different animal from "normal" STM32 mcus. I am off.
