I just bought the Q96 Mini TV Box with 8GB RAM and 128GB ROM:

https://www.aliexpress.com/item/1005004079154677.html

I have managed to boot Armbian in desktop mode with "Armbian_20.10_Arm-64_bullseye_current_5.9.0_desktop.img"

But the problem is that it only allows me to use 1GB of RAM

What do I have to do to be able to use the 8GB?

I have tried decompiling "meson-gxl-s905x-p212.dtb" and changing the value to:
 

memory@0 {

     device_type = "memory";

          reg = <0x80000000 0x80000000 0x80000000 0x80000000>;

};

and I've recompiled it, but I'm still able to use only 1GB of RAM

I don't know what else to try any idea is welcome

Thank you

 

You have bought from a seller that is lying to you.  The amlogic s905l2 can at most support 4GB of ram.  So it isn't possible to have more than that.  What some disreputable sellers do is create a customized version of android that lies about how much memory the box has.  There is no way you can get a box with 8gb or ram and 128gb emmc for $24.  What you have is a box with 1GB of ram.

You're right. I can see real RAM by connecting via adb and "dmesg | grep -i memory | grep -i available"

[    0.000000@0] Memory: 699648K/1027072K available (9833K kernel code, 952K rwdata, 3684K rodata, 935K init, 3574K bss, 327424K reserved)

But how to know real size of flash memory?

All my tries give me fake info...

Open the case and look at the chips installed on the board.  If you can look up the chip specs from the markings, you should be able to figure out how much storage the box has

If the chips themselves aren't fakes too

Hi! I also owned a Q96 Mini Plus (https://www.aliexpress.us/item/3256803907514359.html?gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US). It carries the same brand name with your device but with slightly different chassis. I already tried different device tree blobs (.dtb) with different operating systems. How did you managed to boot the device in Armbian?

For q96 mini plus. The button is inside the box . Remove the plastic and you should see this button. It took me some time to figure it out
