It is plan to extend the support of the free RTOS to M4+FPU architecture?
Definitely. An efficient implementation is not as simple as you might think though.
I have tried also to disable the compiler option in IAR (FPU none) with the same result.
If you are sure that the compiler is not outputting any floating point instructions, and you are sure you have not accidentally turned the floating point unit on, then it is very likely your problem is not connected to the device being an M4F, as the M3 code does not itself use any floating point instructions and should (does) run on M4F silicon (without the FPU being used).
