在使用较旧的部件#s调试时使用Pickit 3的问题

我一直工作良好，随着一些PIC16F部分在20和28针浸封装。当我决定尝试一个项目40针浸我开始有麻烦，我猜因为我选择了PIC16F84，我想现在被认为是一个旧的一部分，因为它只有8兆赫最大（有趣的是，只有少数选择回来时，我选择它）。不管怎样，在这个版本中，PICIT 3固件ISPK3FWY014909JAM似乎很方便地“忘记”如何在调试模式下编程这个设备，它的生产很好，但是我没有任何生产代码。我环顾四周，我想我可以“哄骗”我原来的项目，比如PIC16F18875或PIC16F15375（是的，我知道它们是便宜的零件，现在我猜，其他选项确实花费更多），但是在那里我只需要大量的额外的特征和子系统（实际上是所有的ReGIS）。我正在使用一种或那种方式重命名，并且在很多情况下，你和他们说话的方式也不同），固件需要几百个小时的重试才可以尝试新的芯片类型，谁会为此付出代价？我可以显示整个“分类”，但有时它识别芯片类型，有时它不，不管它总是回来读的第一个字，它尝试是零，它停止。没有专门用于任何其他程序的引脚，没有看门狗定时器使用，它不是LVP和所有电源引脚连接，我已经尝试了多个芯片相同的结果，这不是我的第一个牛仔竞技。我怎样才能找到固件回滚到什么？（为什么我要把这个“霍布森的选择”放在首位呢？等太久才能把东西带到市场，你会因为你的麻烦而受到惩罚吗？多么令人恼火的情况……哦，是的，这是MPLAB X IDE 3.65，如果你想知道的话，是最新最伟大的。

    I've been working well as of late with some PIC16F parts in 20 and 28 pin DIP packages. As soon as I decided to try a project with a 40 pin DIP I started having trouble, I guess because I picked a PIC16F884 which I guess now is considered kind of an old part because it's only 8 MHz max (funny it was one of only a few choices back when I picked it). Anyhow the Pickit 3 firmware is
PK3FW_014909.jam which at this revision seems to have conveniently "forgotten" how to program this device in debug mode,
it does production fine but I don't HAVE any production code to put into it! I'm looking around and I suppose I could "coax" my original project into something like a PIC16F18875 or PIC16F15375 (yes I know they're cheaper parts NOW I guess, other options DO cost more) but there's just TONS of extra features and subsystems in there I DON'T NEED (and practically ALL the registers I'm using got renamed one way or another, and in many cases the way you talk to them is different too), the firmware will need HUNDREDS of hours of rework just to TRY it on the new chip types and who's gonna pay for THAT?? I could show the whole "triage" but sometimes it recognizes the chip type and sometimes it doesn't, regardless it always comes back with readback on the first word it tries is zero and it stops. There's no pins dedicated for programming that are used for anything else, no watchdog timer usage and it's not LVP and all power pins connected and I've tried multiple chips same result, this isn't my first rodeo. How can I figure what firmware to roll back to and how to do that? (And why am I put into this "Hobson's choice" in the first place? Wait too long to bring something to market and you're penalized for your trouble? What an infuriating situation...) Uh, oh yeah it's MPLAB X IDE 3.65, latest and greatest if you were wondering.
