Hey all!
I'm starting this thread because i want to implement my own MKR WAN clone board. I need to slap some new components on it and remove some other ones. I want to know, in my clone board i plan to remove the USB in order to gain some room on the board. However, althought i know how to upload the bootoader to the SAMD microntroller, i don't know how to flash the code, to be a bit more precise what i need to know is: where to store my code on the SAMD21? how to access the desired address? And most importantly, we do agree that using standard Arduino IDE won't work as it will searcxh for COM interface?
Any guidance will surely be a lot of help 
Have a great day,

you can only remove the connector. it is the native USB of the SAMD21.
SAMD21 without bootloader can be flashed from IDE with SWD programmer on SWD pins
oooh ! Thanks! i'll try this way
