C071: CubeMX is generating invalid code

When using USART2 on the C071, CubeMX is generating calls to functions like `HAL_UARTEx_SetTxFifoThreshold` but the USART2 on C071 is a basic UART without FIFO.

Hi, is there an estimate for when this might be fixed?  6.15 was released in July and still had the problem.

Is there a workaround other than hacking the generated code?  Maybe using ll_ instead of HAL?  The ll_ code doesn't have the check and just writes to the CR3 register bits, even though it has no effect.

Regards,

Mike
