LPC54628 Printf Floating numbers doesnt have minus sign

[alpcaner92]

Hi,

I have a  LPC54628 dev board. Im trying to print signed floating numbers, however negative sign is not printed. 

I did the following changes which works for decimal numbers but not floating numbers. 

PRINTF_ADVANCED_ENABLE=1

PRINTF_FLOAT_ENABLE=1

Here is the code. 

Current = -0.001A

SHELL_Printf(" %.4fV  %fA\r\n",temp,Current);

I tracked down to the inner functions of Printf, I found out that the sign is lost during casting. 

fval loses the sign after cast. This function is in fsl_str.c file. 

Can you help me? 

Regards,

Caner
