You mean booting emmc without sd-card? Yes…simply follow steps here: http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:storage#install_os_on_emmc
I have booted debian stretch from emmc…
mmcblk1 is your emmc…you have to modify root in uenv.txt on your boot-partition from emmc
What os have you on mmcblk1p2? Maybe you have to change mountpoints there too
As i see,kernel gets loaded, mount of root+boot works but failed on devtmpfs…is a /dev-folder there?

This is my issue, i follow your wiki and when i doo from the emmc kernel does not seem to find the root device.
where <SD>/boot/bananapi/bpi-r2/linux/uEnv.txt with root=/dev/mmcblk0p2
where <MMC>/boot/bananapi/bpi-r2/linux/uEnv.txt with root=/dev/mmcblk1p2
Not sure how to debug and find the correct device.

ls /mnt/emmc/root not boot
btw. /mnt/emmc/boot/bananapi/bpi-r2/linux/uEnv.txt will be used…your config on boot seems right
I have also uploaded my basic debian-stretch for emmc to gdrive. Make sure you have changed mounts in /etc/fstab when copy rootfs from sdcard

Still not boots? Have you done recursive chown (-R) of lib?
is /mnt/emmc/root/dev empty? make sure it is…

now i see that rootfs seems to be mounted readonly (179:2 is mmcblk0p2 in you list above, but line in log before shows right part…)…strange. can you try my emmc-stretch-image?
https://drive.google.com/open?id=1oP7jy1KrrIOifvImo2nQ59wx3_9hHkgk
simply i did the steps in my wiki
changed emmc-partition-config (0x48)
flash preloader to boot0
create partition-layout on mmcblk1 (via export from sd like the file i appended to my wiki)
create filesystem on booth partitions (p1=vfat,p2=ext4)
copy content of sd-boot-partition
changed uenv.txt (root=mmcblk1p2)
unpacked my bootstrapped debian to root
changed fstab to point to mmcblk1 instead of mmcblk0
unpacked kernel to boot/root

from some reason it does work with your image. what is the root passwd?
I will start from scratch as i mus have miss something.

Ok, another way should be using tar with --one-file-system to pack existing system without mounted filesystems
