Added a way to define custom board in my project

[pguillebert]

Hi

As a uDevKit user, I'd like want to be able to define a board inside my project, because

1. i don't know exactly what i'm doing yet
2. i'm not confortable sharing board definition details, etc

so this is a fairly crude attempt at having a support/board/ local "overlay" directory where boards are searched first, then the uDev provided boards, then error out if not found.

I planned to add it. But not in that way.

I would like to give the ability to set a board definition outside of the udevkit repo :

• directly by giving the path of your board mk
• giving a search path to have a library of your custom boards

Please note that for a commercial usage, you need a specific license

it might be worth considering also a similar system for robot, module or even entire archs, why not.

So far i'm only hacking on my own time - no commercial use but the whole project is under GPL v3, right ? I can use a GPL v3 library for a commercial project, provided i share the resulting codebase.
