各位：
我这边写了一个程序，PE在线调试正常运行，PE断开，重新上电就无法运行。
请帮我看下，问题出在哪里？
硬件肯定是没有问题的，问题应该出在程序上面。
附件是完整工程，我这边再贴下main.c内容
(translation by web translator:
I wrote a program here, PE online debugging normal operation, PE disconnect, power up again will not be able to run.
Please look for me, what's the problem?
Hardware is definitely no problem, the problem should be on the program.
The attachment is complete and I'll post it on my side
