Hello, I have been using a Discovery board with a CortexM4 from STMicroelectronics(STM32f407), programs are being compiled by gnuarm-none-eabi. Function "printf()" is working very fine(I am using a UART to send characters to a computer) however by the time I try to print a float, program hangs. For example this line is crashing the program:
printf("Value of t = %f\n\r", t);
It only happens with floats, integer and string are being properly printed.
Do you guy s have a clue about how to solve this problem?
Thanks,
Mariano
