一、X5 BootLoader的编译

# cd bootloader/libopencm3; make

#cd bootloader;make

二、flash划分：

     /* flash parameters that we should not really know */
static struct {
   uint32_t   sector_number;
   uint32_t   size;
} flash_sectors[] = {
   /* flash sector zero reserved for bootloader */
       {0x01, 16 * 1024},
       {0x02, 16 * 1024},
       {0x03, 16 * 1024},
       {0x04, 64 * 1024},
       {0x05, 128 * 1024},
       {0x06, 128 * 1024},
       {0x07, 128 * 1024},
       {0x08, 128 * 1024},
       {0x09, 128 * 1024},
       {0x0a, 128 * 1024},
       {0x0b, 128 * 1024},
       /* flash sectors only in 2MiB devices */
       {0x10, 16 * 1024},
       {0x11, 16 * 1024},
       {0x12, 16 * 1024},
       {0x13, 16 * 1024},
       {0x14, 64 * 1024},
       {0x15, 128 * 1024},
       {0x16, 128 * 1024},
       {0x17, 128 * 1024},
       {0x18, 128 * 1024},
       {0x19, 128 * 1024},
       {0x1a, 128 * 1024},
       {0x1b, 128 * 1024},
};
#define BOOTLOADER_RESERVATION_SIZE   (16 * 1024)

#define OTP_BASE           0x1fff7800

/* add by alva.mo 20160518, the last sector(128K) for user space */

#define USER_SPACE_SIZE           (128 * 1024)
//#define APP_SIZE_MAX           (BOARD_FLASH_SIZE - BOOTLOADER_RESERVATION_SIZE)
#define APP_SIZE_MAX           (BOARD_FLASH_SIZE - BOOTLOADER_RESERVATION_SIZE - USER_SPACE_SIZE)
