teensy31 stops execution when using float

[gandy92]

porting my avr arduino firmware to teensy 3.1 using arm4, I encountered a strange problem.

The code compiles and uploads perfectly, but execution stops at the first point a float variable is used. Assigning a value to a float variable seems not to be the problem (maybe the code is removed during optimization?) but a multiplication already makes the arm stop dead.

has anyone seen this before and know how to fix this? I can do integer operations for now but eventually I need to use libraries that make internal use of floating point arithmetics.

thanks, Andy.

@gandy92 I've just removed hard FPU. Please upgrade PlatformIO to the latest develop and update all platforms via > platformio update.

Did it help you?

That was fast 😄

Thank you for fixing this, everything works like a charme, now.

The issues from @gandy92 should be fixed as soon as possible 😊
