Where is the bootloader file for the zero?

Looking for the bootloader hex file for the zero.

The tutorial at:


refers to a bootloader hex file that can be used with Atmel Studio. I can't find the file in the location they refer too. I'm on 1.8.1 but have check older versions also.

Anyone know?


Hi @dougJack,

The boot loader files should be on your PC where the Arduino SAMD core is installed.

However, it's easier to grab them from Github: https://github.com/arduino/ArduinoCore-samd/blob/master/bootloaders/zero/samd21_sam_ba.hex

You can also find other boot loaders for different boards here: https://github.com/arduino/ArduinoCore-samd/tree/master/bootloaders

Thanks, I had found that file earlier and carelessly right clicked it to "save link as". I got distracted and didn't check the file. The file contained the HTML of the page that shows the hex data and not just the hex data. I've had so many problems trying to migrate from the Zero and Arduino IDE to the Zero+ICE+Studio that I forgot check the obvious. Thanks again.
