Define your own board - is there an Arduino alike boards.txt file?

[JeroenIoT]

I am a newby here and started to trial platformio and planning to use it instead of Arduino IDE.
Platformio in general works like a charm and seems like big improvement for me.

One of the boards I am programming is the Arduino pro mini (optiboot flashed). In Arduino IDE I am used to change boards.txt whenever I have a specific board which I would like to use.
In platformIO I see a list of predefined boards and I am looking for a way to change (like in Arduino - (boards.txt) the board settings (e.g. Arduino pro mini with optiboot flashed)? Is there an easy way to define your board in platformIO?

Thanks

You have a lot of options:

• Custom Embedded Boards — PlatformIO v6.1 documentation
• clone manifest from platform-atmelavr/boards at develop · platformio/platform-atmelavr · GitHub and place it ~/.platformio/boards and modify it as you need. In PlatformIO Core 3.2 (hasn ot been released yet) you will be able to have custom boards per project. You can try it from Redirecting...
• overwrite board settings on-the-fly per project build environemnts. See Redirecting...

Hello @JeroenIoT,
didi you manage to create the board settings for optiboot bootloader? I’m using Arduino Nano with optiboot, but I’m having problems with uploading.
Would love to hear if you manage to find a solution.

Thank you!

Hey Birchwood, what issues are you having? I haven’t done it in a while, but I’ve created my own arduino compatible boards and uploaded with Platformio without issues.
