Offline compiler for F401RE not work with option used FPU.
I test blinky program in mbed compiler after compile and load to my F401RE board it working well. After that i port program to keil uVision4 and extract project file and build project in Keil uVision it builded success and download to flash already, But LED not blink. I try to debug program and found that the program halted at line wait(0.2);. After change option in Keil uVision at :Hardware Floating point to "Not used" and build project again this time LED blinking. In Keil uVison project that ported from mbed it has no source code of mbed library only object code file. I think mbed staff compile mbed library with option "Not use FPU hardware" Please correct this problem.
