hello. This is Lee Jung-soon of irum D&T.

I am reviewing the nanopi neo air-lts board.

Development is based on wiki content.

I wrote the h3_eflasher_friendlycore-xenial_4.14_armhf_20210618.img file to the sd card, moved it to emmc using the eflasher program, and installed the settings and programs necessary for development in emmc.

After that, I backed up the data I worked on in emmc to the sd card using the eflasher program.
A backup file is created on the sd card at about 7G.
It takes about 20 minutes to try to produce with the sd card backup file (7G).
It's taking too long.

Is there any way to put the 1G data that was finally developed in emmc or sd card into emmc and produce it as it is?

Or is there a way to make production a little faster in the development phase?


I have further inquiries.
The files backed up on the SD card will be deleted at some point. (nanopi-air-emmc.raw)
Will it be erased if I move it to emmc?
The sd card backup file keeps getting erased, so it seems that there will be difficulties when producing later. (nanopi-air-emmc.raw)


====================================
Back up the os files worked on emmc to the Linux PC
Can I move it directly to emmc as a Linux pc backup file and produce it?
(Is there a way to back up 1G, which is the size of the used space?)
