You can see from the log:

1. The size of the Flash file system is 14.6GiB; (GiB concept can be Baidu or reference: the difference between GiB and GB )

2. mmcblk0 is divided into: p1 to p14 in total, 14 partitions.

3. The start and end positions of each partition, for example: userdata partition, starting from: 0x066000000, ending to 0x3a3a00000, total: 13274 MB.
