update the arduino nano every's samd11d to v1.07 which was downloaded from a nano every. uploaded using atmel-ice, no bossac. i used microchip studio 7.
So i tried following the very nicely laid out steps here ... arduino/ArduinoCore-megaavr#51 (comment) but i'm using windows and stuff didn't work and i honestly didn't try that hard.
- connect programming pads to atmel-ice squid plugged into either avr or sam connector using the SWD pins
- provide power to nano every and connect to device ATSAMD11D14AM
- program
- remove atmel-ice and power cycle nano every
- test uploading/serial on nano every with verbose output on upload. should see latest rev like this in the output ... `M_MCU firmware version: 1.07`
