Hi all, i am using lpc1769 and whenever i run the program i will have a hard fault handler when i have a sprintf function in a header file is there any solution to this?

void callprint(int x)
{
char *msg;

sprintf(msg,"%d%d\n",x,x);
Uart_Send((uint8_t *)msg , strlen(msg));

}

You have not allocated memory for the output string.

Try changing

char *msg;

to

char msg[128];
