gcc compiled Experimental Buttonless DFU not working

Experimental Buttonless DFU worked correctly when compiled with keil, but the same example compiled in eclipse by gcc is not switching to bootloader mode. value 0x01 is updated at control point.

Keil and GCC have different stack handling, are you sure your linker file has the correct memory size (RAM) for the device you are using?
