Machine UART deinit() method always returns ValueError exception

[miketeachman]

The UART deinit() method always returns ValueError: Cannot stop UART task

Caused by a bug in the C implementation in function=machine_uart_deinit(), file=machine_uart.c.

Fixed by changing test for tmo With bug:

if (tmo) {
   mp_raise_ValueError("Cannot stop UART task!");
}

With fix:

if (!tmo) {
   mp_raise_ValueError("Cannot stop UART task!");
}

thanks !
