thx Tesla DeLorean + JanI changed the solder bridges on my nucleo board to disconnect fixed USART2 from ST-Links virtual com port.Connecting USART4 works there.When I using different USB Uart adapter (FTDI chip) like this one https://www.amazon.de/Se...

STM32L073 nucleo board.The Port config was done in Cube IDE, the right AF was chosen.I can send from nucleo via USART2 and USART4, BUT only on USART2 also receiving data from PC.Using exactly the same code when switching from USART2 to USART4. void H...

btwUSAR2: I use the nucleo eval board with STLINK. -.-> sending receiving worksUSAR4: usb to uart adapter --> only sending from uc works. Data send from PC not received.Using 115200 baud rate

USART4 does not work receiving data. It works only on USAR2. Sending data works on both. 1) polling on USART4: always timeout 2) Interrupt on USART4 --> Interrupt not thrown
