New ESP32 Board - how to add

1

Hi,

I am trying to add a custom board to the platformio directory, so far I’ve copied a file from platforms/esp32, and following the instructions I can see the new board with platformio.

When I try creating a new project with that new board, I get an error. PIO is updated.

PIO Core Call Error: 
The next files/directories have been created in C:\Users\fault\Documents\PlatformIO\Projects\HelloWorld

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
 `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
 https://docs.platformio.org/page/faq.html

* Report this problem to the developers

o_O? How does that get in there?

Please post your full board JSON file and platformio.ini.

Hi,

The JSON file that I copied and edited is below. I don’t have a platformio.ini as I could not create a new project.

Well I don’t know how you created a project then but PlatformIO somehow thinks you have a chip from the Atmel AVR platform. You can manually create a project by creating an Arduino Uno project first and then overwriting the platformio.ini to reference the correct platform, board and framework.

[env:my_custom_board]
platform = espressif32
board = <board file name without .json>
framework = arduino

When creating the file all I’ve done is copy an existing .json file. I re-did the procedure, and the result keeps being the same.

Then I copied the new .json board file into \.platformio\platforms\espressif32\boards, and I can now create a project with the new board.
