#1
Compiling against ARM’s CMSIS for my Adafruit Metro M0 board fails on Linux, because the include path for the core_cm0plus.h header is specified incorrectly in the compiler invocation:~/.platformio/packages/framework-cmsis/CMSIS/Core/include
The correct path on disk is the same with a capital I (same on GitHub ):~/.platformio/packages/framework-cmsis/CMSIS/Core/Include
I did the same on macOS and it works there, because it uses case-in-sensitive paths. Linux paths, however, are case-sensitive and so the compiler is not including the right one. I checked the package.json, but I didn’t see how to change the way that PlatformIO deduces the include paths. Happy to fix this and make a PR, if you point me to the right location.

For now I am creating a symlink as a workaround:
$ cd ~/.platformio/packages/framework-cmsis/CMSIS/Core
$ ln -s Include include
$ ls -la
total 16

Hold up – the Atmel SAM platform doesn’t even have framework = cmsis as an option

What is the exact platformio.ini here?
Seems like you just have the typo in your platformio.ini
-I$PROJECT_PACKAGES_DIR/framework-cmsis/CMSIS/Core/include
in your build_flags.
