VERY weird 'Failed to execute MI command' problem

[RedScorpio95]

Hi everyone,

I start to question myself and this whole programming thing....

I'm using a STM32F3-Discovery Board and generated a code with STM32CubeMX in default mode. I changed absolutely nothing before code generation.

In main.c I added the following code to the default one:

#include "math.h"

#define PI 3.141

uint32_t sine_val[100];

void calcsin(void){

        for (int i=0; i<100; i++) {

        sine_val[i] = ((sin(i*2*PI/100) + 1)*(4096/2));

       }

}

That's all. So nothing special at all. The thing is, everything is fine but whenever I try to call calcsin() in the int main function I get the following error:

Error in final launch sequence:

Failed to execute MI command:

load E:\\STM32\\Workspace\\090924\\Default\\Debug\\Default.elf 

Error message from debugger back end:

Error finishing flash operation

Also the STM32CubeIDE opens another error message (sporadically?!) which says "No source available for "__muldf3() at 0x8000754"

Can somebody please help?

Hello @RedScorpio95 and welcome to the community.

I didn't reproduce the behavior on STM32F3-Discovery board.

Attached a project. Could you please double check?
