Not able to mount eMMC boot partition

Hello , 

I am working on beaglebone and boot linux via eMMC

i can see 4 partitions under /dev 

root@beaglebone:/# mount /dev/mmcblk0
mmcblk0 mmcblk0boot0 mmcblk0boot1 mmcblk0p1 mmcblk0p2

i can mount mmcblk0p1 mmcblk0p2 without any problem 

But i can not able to mount mmcblk0boot1 or mmcblk0boot0 . . why ?

i get the below error

root@beaglebone:/# mount /dev/mmcblk0boot0 /mnt/boot0/

mount: /dev/mmcblk0boot0 is write-protected, mounting read-only
[ 135.922967] F2FS-fs (mmcblk0boot0): Can't find a valid F2FS filesystem
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0boot0,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

Thanks
