[SOLVED] Sprintf with floating point number crashing into hard fault on STM32L476, working fine with STM32F091 I'm trying to use this C code#include <stdio.h>
char arr[50];
int var_int;
float var_float;
int main (void)
{
while (1)
{
var_int++;
sprintf (arr,"RES 1 %d",var_int);
var_float = var_float + 0.1;
sprintf (arr,"RES2 %d %f",var_int,var_float);
}
}on STM32L476 nucleo kit, with STM32CubeIDE (Version: 1.5.0 Build: 8698_20201117_1050 (UTC)), I'm using debugger, stepping the code and observing variables in expression window, however the code always fails at second sprintf call (the one with float variable). Before trying to execute second sprintf call I can see proper output from first sprintf call, as well as float variable with proper valuebut after second sprintf call I find the MCU executing endless loop after fault. The second sprintf managed to print output up to the floating point part.I started fresh project for this, didn't modify linker file nor any project settings, with exception of ticking "Use float with with printf from newlib-nano"I suppose har
