I’m using nucleo-f446re for sending data by uart when i use uart2 it’s not working but when i use uart1 then it works can anyone tell me why it’s happening.
I using PA2->Usart2_tx
PA3->Usart2_rx
While usart1 PA9->Usart1_tx
PA10->Usart1_rx

The problem you’re encountering with UART (Universal Asynchronous Receiver-Transmitter) on your Nucleo-F446RE board may be attributed to several potential reasons. Given that you’ve noted that UART1 functions as expected while UART2 does not, it’s likely that there are hardware or configuration-related issues influencing this disparity. To better assist you, could you provide a link to the relevant portion of your code for further examination? This could help identify the specific points of concern and provide more precise guidance for resolving the problem.
