We are a company in Korea that is considering an IoT gateway using the Orange Pi Compute Module 4 board.

I need help with two things.

===========================================================
1) Back up the files worked on in emmc to the SD card using the “dd” command.
(sudo dd if=/dev/mmcblk0 of=/dev/sda)  - size 31G


2) Create an image of SD card data using a Linux PC.
(sudo dd if=/dev/sdb of=sems4_jammy_server_202406251642.img) - size 31G


3) Download the sems4_jammy_server_202406251642.img file to emmc using RKDevTool.exe.


The download stops in RKDevTool.exe because the file is large.


Can I back up the files I worked on in emmc in a smaller size and put them back in emmc?




=================================================================
1) OV5647 camera module


If I connect the OV5647 module used in Raspberry Pi to cam1, will the driver be available immediately?
Or do I need to add the driver in the kernel?



help me please

Zo’n technisch probleem met grote bestanden en vastlopende tools herken ik, dat kan je hoofd echt vol trekken. Na uren zoeken naar oplossingen wilde ik even iets totaal anders doen en kwam ik toevallig bij play jonny terecht. In het casino liep het eerst niet lekker en verloor ik een paar spins achter elkaar. Daarna nam ik één keer extra risico bij Book of Dead en dat draaide verrassend uit op winst. Voor spelers uit België voelde dat als een korte mentale pauze van al dat technische gedoe.
