samd21e17 doesn't have icsp header. you have some development board with the samd21e17?

Board has iscp header

the rectangular pads IO, CLK, VDD and Gnd are what you need.

Can i use nodemcu instead arduino as programmer??

maybe. recommended is other samd, but any 3.3V board should do

Hi, started burning bootloader to samd21e17a with nodemcu using above guide ,making connection of vdd gnd clk io rst but i ended with some errors like unknown device found in serial log.
