I'll answer myself. Downloading from the recorded Armbian 22.11 SD card into the bullseye did not work. The download from the nanopi-neo-core_eflasher_friendlycore-xenial_4.14_armhf_20210425.img SD card occurred immediately. It's a mystery to me. From one message I took the command: ssh root@<ip_board_to_be_backup> "dd if=/dev/mmcblk1" / dd of=backup_image.img bs=100M I made an image on a PC. Copied to a USB flash. Launched the recovery command (having previously mounted in /mnt) : sudo dd if=/mnt/usb/backup_image.img of=/dev/mmcblk1 Rebooted the device to boot from mmc. There were errors with "root file system", "flags", "superblock". Launched the fix: fsck -y -b 32768 /dev/mmcblk2p1 (without sudo). Yes, the mmc disk names are different. Who knows the reason, explain. After that, everything worked (just cloning dd does not work)

Hello. I have several new NanoPi-NEO Core devices. OS FriendlyELEC (Ubuntu 16.04.2) was already installed on them, and it does not allow me to boot from the SD card. There is an image created by a script emmc-backup.sh How do I deploy this image?
