It seems that STM32CubeMX does not properly handle tx/rx swap when UART is set to half duplex mode.Steps to reproduce-start a project with a MCU with pin swappable uart, like STM32F030x-enable UART in half duplex mode-enable pinswappingThe incorrect ...

Hi Nesrine, Thank you for your efforts, this is a very corner case but it is good to have it patched up.Best regards, Kari

Ok, you lost me this time... You seem to ignore the fact that I have tested this on real hardware, if swap is enabled on halfduplex UART the physical pin will change.The "halfduplex" mode connects the TX and RX lines internally on one UART to its TX...

Then there is the 'SWAP' which exchanges the RX and TX pins, notably it will make halfduplex to use the pin normallyused for RX. I have confirmed this to be the case with hardware.
