Compile for Nucleo -L053r8

Hi

I have managed to fix the first few compiling errors. I changed following: SDFileSystem sd(PA_7, PA_6, PA_5, PB_6, "sd"); SD card AnalogOut DACout(PA_4);

But now i get the next Error: Error: Undefined symbol feof (referred from wave_player.cpp.NUCLEO_L053R8.o).

I have the newest Firmware V2.J21.M5 on the Nucleo.

Answers are much apticiated. I also will load the Firmware on mBed when it runs on the L053R8.

Thanks Andre

Hello Andre Hochuli,

I believe the application is for targets which use ARM C library, which many nucleo does not support currently. They use uARM which implements only subset of C library, therefore some functions are not available. There's reference on ARM info pages , what is stripped.
