STM32F030K6T6 PA9

We are using ​STM32F030K6T6 PA9, PA10 for UART TX and RX. The BSP is generated using CubeMX, we can see the PA9 does not transmit, if we enable reversal in the BSP, then we can see that PA10 transmits but PA9 does not receive.

​

If we use PA2, PA10 for TX and RX the same transmit and receive code works.

​

Note that the user code is the same along, changes have been done only in CubeMX interface( UART is not in interrupt mode)

​

Is PA9 unusable for UART ​, is it a bug in the CubeMX BSP or the Chip itself?

Could be a board level issue, look at, or provide, a schematic.
