RK-3566-PC EMMC Root Partition gets corrupted frequently

myarikkaya

At random times, ubuntu 20.04 running on emmc breaks. The /boot partition becomes completely empty and all /usr/bin applications become inaccessible.
For example

root@aquadata:~# ls
-bash: /usr/bin/ls: No such file or directory

Even the basic linux application "ls" cannot be used. After this happens, the device does not boot at all on reboot. The only way to reboot is to use SD-boot or rewrite emmc with RkDevTool. I can't understand why.
I think it is a power problem or an automatic update problem.
I am using a 5v 2.4A adapter.
I have about 30 RK-3566-PCs and this problem is happening with all of them, no matter if they are Offical Image or Custom Image.

Can you help me with this ?

There has never been such a situation as you mentioned before
1 Because this situation would not have occurred if EMMC had not been erased, could you recall what special actions were taken before this issue occurred?
2 Provide complete boot logs
3 Provide corresponding version information based on Wikipedia

Reading about the RK-3566-PC EMMC root partition issue reminded me of how frustrating random system failures can be — everything seems fine until it suddenly collapses without warning. It’s kind of like online dating before you find the right platform: things look stable, but the “connection” just doesn’t hold. After seeing a forum mention, I decided to try Join This 50 and Older Dating Site to Meet Mature Singles, and that experience felt like switching to a reliable system. The people there are witty, confident, and easy to talk to, and the conversations flow naturally without glitches or pressure. It’s proof that, just like with tech, sometimes all you need is the right environment to keep things running smoothly.
