I want to make a PCBA based on Nano every(Arduino IDE can still identify it as Nano every).
I have studied the documentation : https://www.arduino.cc/en/Guide/NANOEvery, but I'm still not sure how to finish it.
This is my understanding:
1)burn ATSAMD11D14A firmware;
mattairtech/ArduinoCore-samd sam_ba_Generic_D11D14AM_SAMD11D14AM.bin
Arduino use this as the default firmware?
Do we need to burn it before assmbled?
Can we burn it after assembled? It said we can reprogramme through IDE, I did not understand what they wrote.
2)burn atmega4809 through Arduino IDE
There is a menu named "Burn Bootloader" ,I think it is used to do that after select board & programmer.
Which one is the version for nano every? ( ArduinoCore-avr/bootloaders/atmega8/ ATmegaBOOT-prod-firmware-2009-11-07.hex ?)
Anyone can explain in detail?
Thank you.
