Hello,I'm trying trying to setup an interrupt receive on the U5 MCU using the STM32U5GJ-DK2 development kit. The USART1_IRQHandler does not get triggered at all. Here's my CubeMX config for the USART1:I've sniffed the RX line, so I'm sure it's workin...

Yes, I do. I send 20 and all kinds of data, just to check if the interrupt gets triggered. It doesn't.

RXBuffer is 20. I've tried with 10 and a whole bunch of different values. I've also measured the data with a logic analyzer to ensure consistency. The interrupt RXNE, which should get triggered when the FIFO is not empty, simply doesn't get triggered...

Same behavior. Interrupt not triggered.

I realize that, most of this code is for debug purposes. However my problem here is that the RXNE interrupt, which I have explicitly enabled, does not get triggered.

Just tried it, yes it does work.
