 在bootloader的程序中,需要设置APP应用程序的起始地址,而且编译APP应用程序时,也需要将APP应用程序的起始地址进行相应的更改。
 您说的hello.bin应该是从0开始的应用程序,应该将其修改为0x1800起始,重新编译,同时将usb的bootloader的APP_START_ADDRESS修改为0x1800。
 
 //*****************************************************************************
 //
 // The starting address of the application.  This must be a multiple of 1024
 // bytes (making it aligned to a page boundary).  A vector table is expected at
 // this location, and the perceived validity of the vector table (stack located
 // in SRAM, reset vector located in flash) is used as an indication of the
 // validity of the application image.
 //
 // The flash image of the boot loader must not be larger than this value.
 //
 // Depends on: None
 // Exclusive of: None
 // Requires: None

 #define APP_START_ADDRESS       0x1800
