Bootrom updating

done!

Your baudrate should be set to 19200 bps again!

Press enter key when ready

You do not need to reset the HyperTerminal’s baud rate and can skip the last step if you have chosen 19200 bps. In this case, the system returns to the Boot ROM update menu directly instead of displaying the prompt "Your baudrate should be set to 19200 bps again! Press enter key when ready".
