 First, make sure that the frequency specified uses the correct unit. The frequency is specified in kHz and the safe range is approximately 5000 kHz - 30000 kHz. Furthermore, frequency trimming uses the UART clock as the clock reference, so UART incompatibilities or clock inaccuracies can also result in issues with frequency trimming. If possible, try another UART chip.

 This can especially happen at high programming baud rates, e.g. 115200 baud. Try a lower baudrate, or stick to the default of 19200 baud. Some USB UARTs are known to cause problems due to inaccurate timing as well, which can lead to various issues.
