Mplab X/PicKit 3如何使用代码保护对设备进行编程？

大家好，我想用保护代码编程PIC24F16KL401，以避免任何人读取和复制代码。我的配置位是：首先，它是正确的只是GSS0=作为代码保护？然后，一旦我编程设备，我得到：连接到MPLAB ICD 3…当前加载的固件在ICD 3固件套件版本…01.4818固件类型………DSIC3F/24F/24HTAIL电压检测目标设备PIC24F16KL401找到。设备ID修订= 2设备擦除…编程…以下我MORY区域将被编程：程序存储器：开始地址＝0x0，结束地址＝0xFFFFraseMebug在程序DEVICOK中失败，我再次设置GSS关闭，我尝试程序/调试，但我总是得到相同的错误消息。怎么了？谢谢。



      以下为原文

    Hi to all, I would like to program PIC24F16KL401 with protected code to avoid anyone could read and duplicate code.

My configuration bits are:

#pragma config FNOSC = FRC          // oscillatore FRC interno
#pragma config SOSCSRC = DIG        // disabilito oscillatore secondario
#pragma config POSCMD = NONE        // primary oscillator disabilitato

#pragma config OSCIOFNC = ON
#pragma config ICS = PGx1

// FPOR
#pragma config BOREN = BOR0             // Brown-out Reset Enable bits (Brown-out Reset disabled in hardware; SBOREN bit disabled)

#pragma config GSS0 = ON




First of all is it correct just GSS0 = ON as code protection?

Then, once I program device I got:

Connecting to MPLAB ICD 3...

Currently loaded firmware on ICD 3
Firmware Suite Version.....01.48.18
Firmware type..............dsPIC33F/24F/24H

Target voltage detected
Target device PIC24F16KL401 found.
Device ID Revision = 2

Device Erased...

Programming...

The following memory area(s) will be programmed:
program memory: start address = 0x0, end address = 0xfff
configuration memory
Failed to program device

Ok, I set GSS OFF again, I try to program/debug but I get always same error message.

What's wrong?
Thanks.
