In 461x boards, USART2 is not available. We used those pins for VBAT and VBUS monitoring. I think, At this point it is difficult to change that because of backward compatibility problems. In 461x boards, We can use LPUART1 as second HW serial port. Those pins are PA14 and PA13. It is shared with SWCLK and SWDIO.
That would be fine. LPUART1 is very similar from a driver point of view. But no time to do it in this release. so we'll have to push this to later.
It would be convenient to support two UARTs on 461x boards as well.
