[NUCLEO-U575ZI-Q] USART1 unable to enter receive interrupt when i enable the trustzone.

USART1 work in the non-secure world，it only can send data but not receive data.

You can see the RDE register is changed，but the usart receive interrupt is not triggered

Hi,

I have a similar problem with USART3 as non-secure with TrustZone. I saw you resolved the thread, but what was the problem/solution to this?

Thanks,
