burning a bootloader on a SAMD21E18

Hi!

I used a SAMD21E18 chip for a project of mine and I didn't know that I would need to burn a bootloader in the chip to be able to program it using arduino, via the usb connector. since I used a trinket M0 using a SAMD21E18 to test my first protoype I just assumed I could buy the chip on digi-key and just plug the USB cable and program it.

Iv'e done some research online and I found out I need a specific circuit to burn the bootloader onto the chip, using an atmel ice .

Has anyone ever done that successfully? How do you guys at adafruit program the chips you use on the trinketM0 ?

useful info (I think) :
SAMD21E18 datasheet
- pinout p.23
- programming and debug ports schematics p.1170

ATMEL-ICE datasheet
