Hi 

first of all Please excuse my poor English ! 

I install ubuntu lagecy server on my orange pi pc + and then install it on nand using : $nand-sata-install 

now when i power on my board with sd card (sd card without any image file) my root file system will mount on mmcb1k0p1 and if I insert my sd card after power on root will mount on mmcb1k1p1 (I now both mmcb1k1p1 & mmcb1k0p1 are my emmc)

Now i need to automount my sd card and in my case I insert sd card before power on and as a result I add this line in fstab file

#/dev/mmcb1k0p1                                 /mnt            ext4           0  1

but it doesn't work ! 

how can i mount my sd card automatically ?

You seems to confuse between "1" and "l" ...

Also, make sure there is no more u-boot sectors in the inserted sdcard, otherwise it will boot from it.

I correct my fstab file but still i can't automount sd card (there in no any u-boot sectors in sdcard)

/dev/mmcblk0p1                                 /mnt            ext4                                                                    0       1
 

Mounting by UUID may be a solution for changing mmc device numbers.
