Seeeduino XIAO SAMD21 Breaks When Powered by 220v Source

ok thanks for help
i was unable to understand the path for the flask.bat
i think part of the problem is microsoft onedrive messes with file structure

i find the example to drag and drop the simple_daplink_xiao.uf2
to the daplink xiao via double click reset method as described

this worked and i get the double blue led as someone else said
i have the setup to xiao expansion board and green light on bricked

how to make it work?
i assumed from prior experience that blue led means serial monitor so i tried to use arduino serial monitor to see activity but no luck

can you explain how to send the data? make work from this point?

ok wow i just got it to work i figgured the path problem for flash.bat but was getting unable to detect message
after the drag and drop i could detect and run flash.bat

flash.bat worked successfully

awesome thanks for help

if you get a chance to add to wiki and more discription of whst the path info is for editing

C:\Users\cgwal\OneDrive\Documents\ArduinoData\packages\arduino\tools\openocd\0.10.0-arduino7
i dont like microsoft onedrive but have to live with it

also can you optionally connect to ground and 3.3 or at the servo 8 pin block on expansion board?
avoid having to connect to vcc and gnd adjacent to chip?

i would assume these pins are the same?

thanks to you i have 2 working boards now!
