I bought this S905 box, it has 2GB memory (I can see in Android) but if I use gxbb_p201_2G.dtb then the box cannot boot with LE (it stucks at the S905 boot logo)
If I use gxbb_p201.dtb then the box boots and works (LAN and wifi OK) but with ony with 1 GB memory. The two dtb differs only in one bit.
I tried with 009, 010, 011, 012h, 012h_tsd and 7.95 beta6 tsd versions with the correspondent dtbs (009 and 010 has only 1GB dtb for p201) with the same result.
I also tried other dtbs for p200: The box can boot with the 1GB dtbs (but no LAN and wifi works) and cannot boot with the 2GB dtbs.
Same result with the default dtb.
The normal and the tsd versions are the same, the temp sensor works on the device if I use the normal version of LE.
The device is not rooted.
Could you help me to make a working dtb for this device?
What file do I have to provide from the android?

Obviously your box has only 1GB of RAM.

I have a S805 box that shows 1GB in Android and has 2x512MB RAM chips on board but in reality only 512MB of RAM works and Android firmware fakes logs and visible RAM amount. This is to show how far there factories can go to save a few $$ on RAM.
The "default" dtb contains 4 device trees: 1GB/2GB, S905/S905X. If you leave default device tree on SD card, it's bootloader that chooses device tree depending on RAM amount and device type. The most obvious sign that you have only 1GB RAM is that when you use default DTB, the u-boot picks device tree with 1GB RAM. So either you need to flash a proper firmware that initializes your 2GB properly or you have fake RAM.

As I wrote I can see the 2GB RAM in android, it's about 1.3 GB free after the system started.

OK, thank you. Then it's probably a fake RAM.
But with the default dtb the box doesn't start at all.

The free command says it is 775 MB total...

The free command says it is 775 MB total...I will always be less than 1/2GB because of RAM reserved for GPU and video decoder.

I and several other users (moka88 and john_matrix) have encountered this problem - see this thread.
I returned my box (Tops MXV) to Amazon as it also didn't have Gigabit LAN as advertised.
