That's surprising to me. It is obvious that a library that expects a FPU won't function without it, but a lib not expecting an FPU could just not use it, even if it is present.

Well, I can't link if cortexm_fpu is enabled. I really don't know if any floats are used in that blob, but the .ASM.attributes section in the object indicates that it has been built with soft floats and, thus, the linker complains about that. That's at least what I'm observing here.

Those are the linker errors if I'm building `ikea-tradfri` with `gecko_sdk_librail` and `cortexm_fpu`

OK, sounds like the calling convention is different when not using an FPU. Likely only for passing floats, but since librail actually does use floats this could indeed be a real issue.

I really should read the calling convention specs at some point in time to not be surprised by these things.

So RAIL is the radio HAL, right? They use floats in their radio driver?!?

wtf

I've seen many surprising design choices made by Silabs ... but yes, I wouldn't expect a radio HAL using floats, as well :D But I can't tell - that's the problem with those vendor-specific blobs. Actually, I spent way too long with the integration because of those black boxes. And they weren't willing to let me look inside even after dozes of exchanged emails :/
