error booting after microSD clone

[INSERT]

HiAll, i am new here, and i have a big problem with clone my SD card with armbian image for nanopi neo plus2 H5

 

image: Armbian Focal mainline based kernel 5.10.y

 

I insert master SD to USB adapter and make  sudo dd if=/dev/sdb of=XXXX.img bs=4096 for creating image

 

After complete, i change master SD to backup SD and make sudo dd of=/dev/sdb if=XXXX.img bs=4096 for creating backup SD.

I got thisdmesg.txt

 

in master SD i have

armbianEnv.txtboot.cmdfstab

 

 

 

Where i make mistakes?

Sadly this is quite common - dd is not to trust. Just like Aliexpress 

Probably another move?

Igor, thanks! it's good link for me,

 

now i need find method of clone my 8Gb SD(original 100% ) to SD with less capacity, i find this youtube manual maybe it's work, i wiil test it.

 

And i found RPI-CLONE, he include function for clone image to SD with less volume capasity.

 

Somebody use this programs?

one question more :

 

I have 8Gb SD card, with all data of 2Gb only 

 

Can i cutting like DD if=/image1.img of=/image2.img count=3000 bs=1M for build 2Gb image, Do I need to do something else for boot image (like remap image2 or END marker for him)?
