关于主板配置文件内-IMG尺寸的分析

找对分区，直接fdisk即可知晓大小。

然后对比大小按照10 至 16进制 转换

就出现如下的一些情况。

# fix this up by examining /proc/mtd on a running device

# Boot image size is 16384 x 512 bytes = 8388608

# You can double check it with fdisk -l /dev/block/mmcblk0p8

BOARD_BOOTIMAGE_PARTITION_SIZE := 0x00800000

# Recovery image size is 10240 x 512 bytes = 5242880

# You can double check it with fdisk -l /dev/block/mmcblk0p8

BOARD_RECOVERYIMAGE_PARTITION_SIZE := 0x00500000

# System image size is 1228800 x 512 bytes = 629145600

# You can double check it with fdisk -l /dev/block/mmcblk0p2

BOARD_SYSTEMIMAGE_PARTITION_SIZE := 0x25800000

# User data image size is 4194304 x 512 bytes = 2147483648

# You can double check it with fdisk -l /dev/block/mmcblk0p6

BOARD_USERDATAIMAGE_PARTITION_SIZE := 0x80000000

BOARD_FLASH_BLOCK_SIZE := 2048
