As the title suggests, im having a problem using HAL to make some USART echo.
I tried the same approch on a nucleo-f031 and its working wonderfully.
I can print the whole hyperterminal string, but i cant reach the receive interrupt. Even if i set the RXNEIE bit manually it doesnt trigger the USART2 interrupt.
Just to clarify, i bridged both connection SB62 and SB63 so i can see the USART communication on a logic analyzer.
im hoping for help
