持久绝对地址变量不起作用

背景：MPLAB X IDE 4.15、XC32 V2.05、和声V2.05、定制板使用PIC32 MZ2064 DAH176、NEWAVEN NHD-4.3-48022EF-ASXNα-T显示（4.3）、480X227像素、4线触摸触摸屏。我用其他处理器做的是，我将有一个特殊的消息重置并触发引导加载程序。它是一个简单的布尔函数，在主应用程序中，如果接收到特殊消息，将变量（EngIootLooter）设置为true；在Bootloader中，如果EngBootLooter为true，则在将Bootloader设置为false之后强制Bootloader；如果一切都变为地狱，则强制引导加载程序W。这是一个开关。这允许软件和硬件方法进入引导加载程序，并且已经证明对我来说是非常有用的。问题是，由于某种原因，我的变量声明根本不起作用（同样的代码，保存地址，例如为PIC32 MX130F064 D工作）：编译器说它讨厌我的脸。它给出的原因如下。我只是不明白。这甚至不会导致引导加载程序（传统的，而不是LIVUEPATE）的问题。

    Background: MPLAB X IDE 4.15, XC32 v2.05, HARMony v2.05, custom board using PIC32MZ2064DAH176, Newhaven NHD-4.3-480272EF-ASXN#-T display (4.3", 480x272 pixel, 4 wire resitive touchscreen)

I'm having a heck of a time with a variable that I use to communicate between the bootloader and the application. What I've done with other processors is that I'll have a special message reset and trigger the bootloader. It's a simple boolean that works as follows: in the main application, if the special message is received, set the variable (enterBootloader) to true; in the bootloader, if enterBootloader is true then force the bootloader after setting it to false; if everything goes to hell, force the bootloader with a dipswitch. This allows a software and hardware method to enter the bootloader and has proven quite useful for me.

The problem is that for some reason my variable declaration is simply not working (this same code, save for the address, worked for a PIC32MX130F064D for example):


bool enterBootloader __attribute__((persistent, coherent, address(0x80001000)));


The compiler says it hates my face and the reason it gives is the following. I just don't get it. This didn't even cause problems in the bootloader (traditional, not liveupdate).
