How to use platform-atmelsam with framework-cmsis-atmel?

[RudolphRiedel]

I am trying to use atmelsam but all boards are using one of the Arduino or Arduino-like frameworks. Only samc21_xpro is an exception but only in that it has no frameworks defined - how is this supposed to work?

I can add a custom board file to my project/board and add all the includes manually to project/include. This kind of works but not only does it defeat the purpose of PlatformIO a bit, I am pretty sure it does not even work since I still have no startup-code and at least the stack is not set up.

But as soon as I add "framework = cmsis-atmel" to my platformio.ini, platformio bombs out:

There is no support for CMSIS framework at the moment. The empty framework field means that user is responsible for bootstrapping a working firmware (including startup routine, linker scripts, etc).
