I’m also trying to do the same thing.
Mainly to be able to add custom software packages.
I’m basing my work on
- Help creating custom platform that builds and uploads custom firmware
-
Adding a new framework
And - Custom Development Platforms
I haven’t been able to do that.
I originally had the idea to create my own platform so I could add custom boards that may or may not have the device supported by platformio, plus the ability to add a custom toolchain also looks interesting.
However, I’m considering really badly to drop that idea, because it looks like a very large endeavor, and it seems that maybe given certain examples (like this one How to create a Custom Platform with a custom linker script), the ability to use a different linker script, a different compiler and add custom code to my project, doesn’t necessarily require a custom platform.
In any case, I’m curious if you managed to actually create your own platform.
