Hi, At the beginning I would like to emphasize that I am not an expert in linux :) I use bananapi m2 + v1.1 in my project. Until now everything worked well with the SD card on armbian 5.25. My project is now finished and would like to run the system from emmc. I used armbian-config to move system from SD card to emmc. I chose the only option: Boot from eMMc – system on eMMC. Everything went well except the message (while formatting):

EXT4-fs (mmcblk1p1): Unrecognized mount option "compress-force=zlib" or missing value

mount: wrong fs type, bad option, bad superblock on /dev/mmcblk1p1,

       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try

       dmesg | tail or so.

 

After removing the SD card, system does not start, it always stops at the same point.

I connected the serial debug and here's what I received:

When I insert the SD card everything works as always. I can mount / dev / mmcblk1p1 and it looks like the directory structure has been copied correctly. I have two BananaPi’s  boards and both behave the same way. So it's probably not a hardware issue. I searched the forum and did not find a solution to this problem.

Anyway, has  someone any Ideas to get the EMMc working?

 

Problem solved. I downloaded the latest version of Armbian. In this version, the system transfer from sd to emmc worked as expected.
