各位工程师好：
我自己编写了一个基于28377D的CAN Bootloader程序，程序位于FLASHA和FLASHB。要升级的程序放在FLASHE。
目前的问题是，上位机传送烧写完之后，dsp断电重启不能跳转至FLASHE中的APP程序（通过GPIO口高低电平判断是否进入bootloader）
随后，我进行了以下几个实验：
（1） 将APP程序利用仿真器烧入FLASH-E（不擦除FLASHA、B中的Bootloader程序），DSP开机后可成功由Bootloader跳转至APP程序；
（2） 使用上位机向DSP的FLASH-E中烧写HEX文件，利用仿真器擦除FLASHA、B中的Bootloader程序并重新烧写Bootloader程序（不擦除FLASH-E中的 APP程序），在线单步运行时，可以由Bootloader跳转至APP程序，并自动运行；
（3） 我分别对比了HEX数据、利用仿真器烧入FLASH-E中的数据和利用上位机程序烧入FLASH-E中的数据，对比结果是地址和数据完全正确。
以下是跳转语句：ENTRYADDR为FLASHE前的BEGIN起始地址
static void(*APPEntry)(void);
APPEntry = (void(*)(void))(ENTRYADDR);
ESTOP0;
(*APPEntry)();
以下为Bootloader程序的CMD文件：
