This week I worked on defining my final project idea and started to getting used to the documentation process.

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
both SAMD and AVR can work without bootloader. For SAMDs, the role of the bootloader is to accept firmware uploads through serial over USB, without any additional hardware. Hence you only need a programmer connected to it the first time you flash the bootloader. But if you wish, you can also keep using the programmer and edbg every time you upload, it's simply a lot less convenient. Arduino stores its binary in a hidden folder before uploading, so you could simply find it and upload it with edbg instead.
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
For the AVR, uploading through UPDI requires some USB-serial programmer connected to it, because the AVR itself doesn't support USB. Optiboot is an optional bootloader that can take uploads through a regular serial port of the AVR instead of the UPDI port. But you will still need a USB-serial adapter next to your AVR. This is similar to how Arduinos (ATmega type) work too, they have a serial USB adapter onto the board, connected to one of the serial ports of the ATmega, and take firmware uploads through there.
