Hi. I installed Armbian Server on my TV box (Ugoos X3 Pro 4/64 x905x3) to the NAND, and I have some trouble with the RAM size in the system. I use meson-sm1-ugoos-x3.dtb.

It turns out that only 1.8GB of 4GB RAM is available in the system.

On the Russian forum 4PDA, I found some information on how to fix this.

I repacked the DTB file and changed memory@ from 0x40000000 to 0xFF000000.

After that, 3.8GB RAM appeared in the system, but it turned out the system was unstable and randomly froze.

However, when I installed Armbian from an SD card, all 3.8GB RAM was available in the system, and the system worked fine and stable. I also used meson-sm1-ugoos-x3.dtb.

Is it possible to fix this and use all available RAM?

So you are saying that when you copy the working SD card install (by working I mean that it has the correct memory amount) to emmc that the problem occurs?

yes!

I just noticed from your screenshot that you aren't using Armbian.  You need to ask support questions for non-armbian software from where you got your software.  Ophub is a fork of Armbian that used the Armbian name without permission.  They do not contribute to Armbian development nor do they contribute the these forums.
