【飞思卡尔 MC9S12】BootLoader 上位机
本篇讲述BootLoader上位机开发。
Bootloader上位机、下位机以及用户App 范例源码：https://gitee.com/beatfan/freescale_mc9s12xep100_-bootloader.git
此上位机采用WPF框架，C#语言开发，支持周立功的CAN设备和ValueCAN。
由于手头上暂时没有硬件，无法实际演示，大家先凑合看示例图。
注意，有很多人操作误区在于，将S19文件选择成了Bootloader，这里应该选择app，就是你自己的应用程序。
Bootloader与App分别占用2个非分页区。
Bootloader: 0xC000-0xFFFF（实际到0xF7FF，保留一个sector给vector table）
Application: 0x4000-0x7FFF，加上其它分页区（转换成全局地址为0x7F4000-0x7FFFF）
若是不知道怎么写App，可参考范例
BootloaderPage.xaml -- Bootloader刷写界面
S19ParseWithText -- 为S19文件解析查看界面，仅用于查看数据，与刷写无关
ClassBootloaderForCAN -- 协议封包解包在
CANCommon -- 通用的CAN连接断开、发送接收的类（实际收发在CANDevices类库，大家也可以添加自己手上以后的CAN设备的API，以便于支持）
VAlueCAN和ZlgCAN.xaml -- CAN配置控件，用于设置各个不同的CAN配置参数，方便转换成通用的例如波特率的参数。
