This directory contains tools to help users create bootloaders and arduino hardware packages for custom-made SAMD boards. All you need to do is filling your board info in a plain text config file (just one!), create variant.h and variant.cpp files describign the pins for Arduino IDE, and then run a script, which will do (almost) everything else for you - build the bootloader, create a board support package following all the
Arduino platform specifications, even create an index.json file.

Note: the script will not flash the bootloader to the board for you

• you need to do it separately, e.g. using Microchip Studio (formerly Atmel Studio), or Adafruit's DAP library.

Requirements: the following must be installed on your system

• GNU Make
• Python 3
• Arduinoe IDE, version 1.8 or later
• Adafruit support package for SAMD boards

Detailed instructions will be provided later.

Currently, the following variants are supported:

• SAMD21: SAMD21E17A, SAMD21E18A, SAMD21G18A,
• SAMD51/SAME51: SAMD51G19A, SAMD51J19A, SAMD51J20A,SAMD51P20A, SAME51J19A
• Untested: SAME54N20A, SAME54P20A
