根据串口输出信息，由最后一条调试信息定位到main.c的代码如下：
// Jump to downloaded image (use the physical address since we'll be turning the MMU off)...
//
dwPhysLaunchAddr = (DWORD)OALVAtoPA((void *)dwLaunchAddr);
OALMSG(TRUE, (TEXT("INFO: OEMLaunch: Jumping to Physical Address 0x%Xh (Virtual Address 0x%Xh)...\r\n\r\n\r\n"), dwPhysLaunchAddr, dwLaunchAddr));
// Jump...
//
Launch(dwPhysLaunchAddr);
当时，我试着重新烧写NK，可仍然会出问题。
