**Firmware** Adafruit CircuitPython 6.1.0 on 2021-01-21; Adafruit Feather STM32F405 Express with STM32F405RG **Code/REPL** import board import busio uart = busio.UART(board.TX, board.RX, baudrate=9600) uart.deinit() uart = busio.UART(board.TX, board.RX, baudrate=9600) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: Hardware in use, try alternative pins **Behavior** What I expect is that the deinit will release the bus, but it doesn't seem to. Is there an alternative way to release it?
