Hi,

 

I want my application to be able to go to bootloader. It should not use hardware reset. How can it be software controlled? 

 

Could you tell me how to implement it?

Call NVIC_SystemReset()

Might not work if you are debugging (check Errata).

Or deliberately let the Watchdog do the reset ...

  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
