同一PIC32MZ中有多个Bootloader？

标题似乎有点奇怪，我也没有得到确切的，我应该写在那里，但希望我能让你明白我想做什么！我将有一个主引导加载程序和二次引导加载程序都将驻留在不同的内存区域（可能是引导闪存或程序闪存）。一个引导加载程序将一次激活，另一个将不活动。-让我们考虑一下，主引导加载程序是活动的，现在我将下载我的应用程序。固件。我也从应用程序固件中读取激活的引导加载程序版本，这样我就可以检查是否需要更新Bootloader。-如果我需要更新Bootloader，那么非激活引导加载程序将被激活，它将用更新的Bootloader替换以前的激活引导程序。二次引导加载程序将切换到非活动模式。因此，二次引导装载器在更新主引导装载器时才变得活跃。在整个过程中，我想为主引导装载程序、辅助引导装载程序版本和一些固定内存位置的自定义配置数据保留一些内存区域，并且可以从PR访问。IMARE，二级以及应用固件。

    Heading seems kinda weird, I am also not getting what exact should I write there, but hope I am able to make you understand what I want to do exactly!
- I will have Primary bootloader and secondary bootloader both will resides in different areas of memory (may be boot flash or program flash).
- One of bootloader will be active at a time and other will be inactive.
- Let consider, Primary bootloader is active, and now I will download my application firmware. I am also reading the active bootloader version from application firmware so that I can check whether I need to update bootloader.
- And If I need to update bootloader then inactive bootloader will be activated and it will replace previously active bootloader with updated one. And secondary bootloader will switch back to inactive mode. Thus secondary bootloader only become active when it have to update primary bootloader.
- In whole this process, I want to reserve some memory area for Primary bootloader version, secondary bootloader version, and some custom configuration data with fixed memory location and can be accessible from Primary, secondary as well as application firmware.
