大家好，经过多年的微控制器，我第一次遇到这个错误，我花了半个下午试图摆脱它，但没有成功。我的情况如下：我在一个新的板上有AdSPIC3FJ64 GS606，它被ICD3正确识别，我使用PGC/PG。D3端口（正确设置在MPLAB 8.88 -是的，我仍然使用旧版本，我不理解任何在新的……）如果我使用ICD3作为程序员，一切工作良好的所有振荡器配置（内部，XT，有或没有PLL……）。当我使用它作为调试器时，程序被写入，验证，但是我得到0040错误。我已经检查了微控制器的安装，它看起来很好，程序员引脚似乎是正确的引脚上的连接器，复位只有一个100K上拉，它是直接连接到TH。
电路板几乎完全无人居住（只有SPI总线上的ADC和M3322收发器，我不认为它们能在这一点上干扰），我已经尝试过任何可能的保险丝设置组合，但结果总是一样的。当编程和执行速度根据振荡器设置改变时，我倾向于排除振荡器或板本身的硬件问题。IC PIS与ICD连接器之间的电阻是0.4OHM，所以我也排除了焊接的一些问题，ICD电缆是标准的短路，作为USB电缆。连接器只放置在离微控制器几毫米的地方，所以轨道很短。程序还没有做任何事情，只是将一个端口设置为输出并闪亮LED，因为我把所有的东西都移除了，以确保那里没有干扰。我明天唯一能做的就是组装一个第二个
PCB，测试一个只排除一个微控制器故障，所以任何建议都是非常欢迎的。谢谢！吉安保罗

Hi all,
after many years of microcontrollers I have encountered for the first
time this error and I have spent half afternoon trying to get rid of it, but without success.
My situation is as follows:
I have a dsPIC33FJ64GS606 on a new board, it is correctly identified by the ICD3, I am using the PGC/PGD3 port (correctly set in MPLAB 8.88 -yes, I am still using the old version, I do not understand anything in the new one...).
If I use the ICD3 as a programmer, everything works fine with all oscillator configuration (internal, XT, with or without PLL...). When I use it as a debugger, the program gets written, verified, but I get the 0040 error.
I have checked the mounting of the microcontroller and it seems fine, the programmer pins seems to be going to the correct pins on the connector, the reset has only a 100k pullup and it is wired directly to the ICD connector.
The PCB is almost completely unpopulated (only an ADC on the SPI bus and a MAX3232 transceiver, I don't think they can interfere at this point), I have tried any possible combination of fuse settings I could think of, but the result is always the same.
Since the microcontroller works when programmed and the execution speed changes according to the oscillator setup, I tend to exclude an hardware issue with the oscillator or with the board itself. The resistance between the IC pis and the ICD connector is 0.4Ohm, so I would also exclude some problem with soldering, the ICD cable is the standard short one, as the USB cable. The connector is placed only a few millimeters away from the microcontroller, so tracks are very short.
The program is not doing anything yet, just setting one port as output and flashing a led, since I removed everything to be sure that there were no interference from there.
I am quite out of ideas, the only thing I can try tomorrow is to assembly a second PCB and test that one just to exclude a microcontroller failure, so any suggestion is very welcome.
Thanks!
