If you want to reset the Seeed Studio XIAO SAMD21 , perform the following steps:
Connect the Seeed Studio XIAO SAMD21 to your computer.
Use tweezers or short lines to short the RST pins only once
The orange LED lights flicker on and light up.
Please note: The behavior of the built-in LED is reversed to the one on an Arduino. On the Seeed Studio XIAO SAMD21 , the pin has to be pulled low, whereas on other micro-controllers it has to be pulled high.
