problems about add a new board to arduino ide

I want to add a new board to arduino ide, I created board.txt and platform.txt. But when compiling, it didn't find my toolchain. An error like this: no such file or directory. Head files also have this problems.

Arduino IDE and Arduino builder support custom board definitions from [hardware subfolder](https://arduino.github.io/arduino-cli/platform-specification/) of your sketches folder. These definitions can use core classes and tools from installed board packages.

This GitHub repository contains my settings for boards I use for my project and to develop Arduino libraries. You can use it as starting point for your boards specialties.

![folders](my_boards.png)

All boards in this repo are only additions to installed 'official' board packages. My files contain only definition of the board in boards.txt, the folder in variants and platform.txt file contains only additional entries. The file programmers.txt contains sample definitions of 'programmer' entries for OTA upload without the IDE detecting the network port.

## Boards

### AVR architecture

Boards defined here use build of [Optiboot bootloader with `copy_flash_pages` function](https://github.com/Optiboot/optiboot/pull/269) (for ArduinoOTA library). platform.txt contains entries for sketch upload over network to ArduinoOTA library. All boards refer official Arduino AVR core and tools.

The official Arduino Mega doesn't use Optiboot bootloader. It has a 4 kB bootloader. The board definition here is changed to respect 1 kB Optiboot bootloader. The AVR package can use arduino:mega as variant reference to official package, so the variants folder doesn't need to be copied here. 

I have [a small series ATmega1284p board](https://github.com/budvar10/Arduino-ATmega1284P) by budvar10. It has perfect Uno pins compatibility. The pin mapping in variants is copied from budvar10's repo.

### SAMD architecture

Could I take a look at your .json file. Besides, where is your toochain?

it is not a boards package with core and tools. only boards definitions which refer official packages for core and tools. read the readme and the linked documentation.

here is an example of a boards package which refers the Arduino boards packages for core and tools
