I am facing an Issue with my PIC16f877A controller.
Its working in Debug mode with PicKit3 connected. But when I program the device for release mode, It gives no sign of working.
I am using MPLAB X with XC8 compiler
I have also connected 10k resistance between MCLR & VDD.
But still unable to resolve the issue.
Here is my main.c
#include "lib/System/config.h"
#include <xc.h>
#include <pic16f877a.h>
#include <stdio.h>
#include <stddef.h>

#include <stdbool.h>
#include "lib/UART/UARTLib.h"
#include "lib/I2C/I2CInterface.h"
#include "lib/I2C/idmodule.h"

#pragma config LVP = OFF // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)

}
Please help me debugging the issue.
