You do not have 3 GB, this is a fraud of the seller.

Maybe... so 4 *512 KB ICs, but then why bother marking the ICs with different part-numbers?

And what about the U-Boot? It reports:

U-Boot 2015.01-ga4d8f5c-dirty (Dec 07 2017 - 19:23:54)

DRAM:  3 GiB

Why bother faking that? Who's ever gonna look at it? 

Is it possible to replace the boot loader with a "good" one?

Burning tool 2.1.2 can't do it, even if I short the 2 ROM IC legs. Is there a better tool?

 

 

@Nuno CruzYour machine seem the same as mine, how much RAM do you see in Armbian?

Thanks!

Could you tell me what Armbian version and what dtb file you are using?

Hello,

I installed the armbian image on an sd card (Armbian_19.11.3_Aml-g12_xenial_legacy_5.3.0_desktop_20191126) then I inserted into my H96pro+ box(amlogic s912) and booted. the linux installation process started (creating user name, password...).

 I logged to my user account but at the end there is no GUI interface (the linux stay in text mode).

Please help me to log into the GUI interface/

Is it possiblee to install Armbian to an Amlogic S905Y2 box? More specifically the A95X Plus?

I've seen various X problems when moving up through the builds. It can be down to kernel, dtb etc.
If X is crashing according to fbdev in /var/log/Xorg.log, its probably the kernel or dtb (also after startx).

If lightdm gtk greeter consumes 100% on 1 cpu, try to change the greeter - take some tips from https://cialu.net/how-to-solve-failed-to-start-session-with-lightdm-and-xfce/
Disabling selinux at boot fixes a lot of strange issues.

At the end of the day, it seems to be better to move onto a different armbian build or back to a good one, particularly kernel files and modules.

I'm trying to install it on X96S with S905Y2...

I have 2 versions, the 2g/16gb and 4g/32g.

 

in the 2g version i could boot into armbian (used the default dtp, tryed to change for many but only worked on the ugoo default). But no bluetooth and no wifi. This one come with wifi chip RTL8723BS

 

in the 4g version the armbian load, but when ask for the root password my keyboard isn't working. I tried 3 keyboard on USB but no one worked. It remains still waiting for the root login. This version came with the wifi "Ampack AP6255", but i couldn't start armbian to test,... don't know what to do for USB to work with the keyboard and couldn't find a solution online.

 

Images from both X96S chips (armbian worked on 2g)

Don't remember the image version, the dtb was auto selected and based on the board name that I have in the installation it's kharas vim2

Hi all,

 

thanks @balbes150 for the great effort on porting armbian to this "cheap" TV boxes.

I need a headless linux box, and I have a minx NEO U1 that I don't use much anymore, ergo Armbian!

So I basically need a linux box with LAN connection, don'r really care about HDMI or graphics.

I've read around the forum, and dispite being a popular box, the neo u1 is not discussed much in the armbian.

Apparently I already have multiboot set up (I was using libreElec in the box in the past),  I made it working open/libreELEC many years ago. so much time ago that I can't find the USBnor dtb files I was using.

Anyway, the box boot up fine the Armbian_19.11.3 (server) image with almost any *gxbb* dtb.

 

I think the right dtb it could be the meson-gxbb-p201.dtb, I have no error, the system can detect 2Gb of RAM, and from ifconfig and dmesg I would say that eth0 interface is up, but unfortunately the ethernet network doesn't really work...

The system clearly sees the ethernet port as something logs in dmesg when I plug/remove the cable but it never picks up an IP address (at least not an IPv4 one) from the router DHCP server. I'm sure the router/cable are OK, as any other machine gets an IP correctly with the same cable/port/router.

 

Curiously with meson-gxbb-p200.dtb I have error some PHY LAN-related error (I haven't collected the debug info, but I can if that could be helpful).

I don't have a serial cable to USB to log in UART mode.

I've tried p200 since in the libreELEC github devicetree there is a gxbb_p200_2G_minix_neo_u1.dts, and it inherit the LAN from gxbb_p200_2G.dts. So if I follow/fix the error I have using the meson-gxbb-p200.dtb I may solve my LAN issue.  

 

Does anyone have this box and was successful on booting up with a working LAN? (and or have an idea what I could change to make LAN working)

 

Cheers

 

EDIT: I've checked the LAN connection with Android and it works (I actually wasn't sure about that)

 

EDIT2: I've tried to play around with dts files, modify/compile, but I came to the realisation that the ethernet support for the mason family (at least gxbb) is completely broken! I'm so surprised that the lima driver kind of works, while the ethernet hardware is kind of unsupported! I gave a try to the wifi then, after setting up the firmwares files and configure wpa_supplicant and changing the interfaces... I still don't have wlan0 in the possible interfaces, although the brcmfmac module load without errors.

I was thinking to swap the on board u-boot with more recent version, but I can't mount the mmc, as I can only see the mmcblck0 device and non its partitions! So unfortunate.  Last resort fo me, is try to load a u-boot from usb. I've found some handwaving instruction in this forum,  but I don't think I fully understand it.

Anyway, do you think that swapping the u-boot may solve some of the board issues?

 

[Amoren]

Hello, I installed the armbian linux (h96pro s912 box) on a sd card. It runs very well.

Now I want to install it to the emmc nand of my box but there is no option to do this 

on the armbian settings app (blue screen).

Any other option to install it to the emmc nand flash?

Nand flash is not supported in recent linux kernel. If you have emmc, in the root folder you'll find install.sh to do what you want.

You should only use the DTB that are included in the image you are using. If you need to change something in them, you need to use the DTB from the image as the basis.

You can try to search older 3.14 based version of Balbes work, but I don't think the images are still available. You may look here:

First up... THANK YOU SO MUCH! to you @balbes150

I bought the original H1 variant 'H96 Pro Stick' (an Amlogic S912 in stick form!) as soon as it came out direct from GearBest on a special deal for £35!
The original Android 7.1.2 firmware was bad, but SuperCeleron over at FreakTab made a decent 'full-android' and 'android-TV' OS that i have tweaked myself. That was it for development on my board, and that almost 3 years ago now.

I had once, way back then tried this before, and after trying 10ish random dtb.img's for S9xx i would get past login, but it would always get this repeated text across the screen that would stay there and i never did get to the desktop.
I am now typing from an 11 year old 32-bit Intel Atom NetBook with 1GB ram! :'(
It is my 'PC' ...and honestly... i can do more from my 64-bit OnePlus 5T in Termux (Arch/Debian/Ubuntu proot) than this old thing.
I know the S912 is good for Linux in multi-core benchmarking... so all this time later... i tried again....
And with the newer documentation you have now... it was alot easier than last time! and it worked... first time too!
FINALLY I get to try out Armbian!!!!
So thank you very much for your work all these years, it is appreciated!
The rom i got was Ubuntu and it runs fast! no long wait times for apps to open up! a much needed 64-bit PC i have needed all this time!!
 

Just one question please (or anyone else out there reading this essay!)
As the case with alot of devices... wifi & bluetooth is not working. I found a website from a guy who used my H1 H96 stick and he forked your 4.9 kernel sometime back & modified it for crypto-mining purposes, so it has alot of documentation. On his GitHub it has my wifi & bluetooth drivers.
How do i add them into this rom?????

ONCE AGAIN... A MASSIVE THANK YOU!!!!!!!!

Hello Balbes,

 

thank you very much for your beautiful builds

I have one question: I have some older Ubuntu 18.04 build with 5.1.0-aml-s905 kernel and I want to compile media_build drivers to apply a patch for my dvb-card which works only partially (dvb-s works, dvb-s2 not, seems to be a common problem for dvb-adapters of this type). As far as I understand, I need a kernel source (or kernel headers) to be able to compile. Where I can get them for my kernel version (or do some other headers/source will do for compilation?). Unfortunately I don't know much about linux tinkering - I can follow instructions but I'm not able to overcome the unexpected problems and don't really understand what do I do mostly. What I did try - I have installed kernel-package and linux-source packages (which were 4.15.0 -  but I have 5.1.0 kernel and need same source, right?) and run make oldconfig && make prepare. After that I run build inside media_build and of course the compilation failed, it can't find time.h, features.h etc. inspite of the fact that they are present in /usr/include and build_essentials (and all other prerequisites) are installed

 

It would be great if you could give me a couple of tips how to compile media_build in your distros.

In the network repository is a new kernel 5.3 5.4 version and headers for them, try to take them there.

what do you mean with "network repository"? your new builds on yandex disc or your Build-Armbian repo on github?

Hi guys, been a whole week now i have waited for a reply ^^

I dont expect to be answered right away but over a week now and others are being answered before me?!?

I dont need my hand to be held, just need some general steps i need to take please OR point me to some documentation and i will do it all myself.

PLEASE! ANYONE?!??

So, again....
Thank you for the distro, only problem is wifi doesnt work, could ANYONE please tell me roughly what i need to do next to get wifi (i have my devices wifi & bluetooth drivers) how do i add them????

Been a whole week since i got Armbian now, and i am still unable to use it as i cannot download anything.

I cannot find any documentation here, Github, MXQ project or Freaktab on 'adding drivers'. (if there is none, perhaps that should be added. I dont mind contributing by writing it up myself as i NEED the info anyway as i will be doing it on my device).

 

Until someone helps me, i cannot use Armbian, so please any help is truly appreciated, thanks.

These drivers are from another (non-compatible) kernel, if you ask such questions, then you do not add any (you need to be a system programmer to write these drivers again).

[scott90420]

Thank you @balbes150 for the quick reply AND the great work you do.
So... basically adding wifi is pretty much a no then :'( 

Shame, i have no ethernet as its a s912 stick, not box.

I will have to buy a USB to ethernet cable then.

 

One more thing:

I really like this project and would like to, in a small way, contribute.

 

Idea:

I successfully burned my USB via an android app called 'EtchDroid' (open source - F-Droid).

This had me thinking, i want to make a native android Armbian tool, no PC needed, it will:

1. Extract DTB IMG from the device.
2. Burn the distro IMG to USB/SD card, like EtchDroid.

It will work via a terminal app (whilst booted) and also available as a Magisk/TWRP flashable ZIP too, so it can be also be used via recovery (in case bricked/boot-looping)

I have found on GitHub an Amlogic DTB tool.

I have the AML_autoscript & AML_autoscript.zip.

 

So...

I am currently trying to work out how to apply the AML_autoscript.zip via recovery/magisk and not the stock 'Update' apps we have on our boxes. Question:

1. Do you have any ideas for this??
2. Where/what does the AML_autoscript.zip change and how does it do it?

 

THANK YOU SO MUCH BALBES150 YOUR TIME, EFFORT & EXPERTISE IS REALLY APPRECIATED!!!

I really think Armbian will be more accessible to the masses if it was in an app like i am trying to make here, it can be on F-Droid, PlayStore, APKmirror etc so it reaches a larger audience.

And also takes care of the only 'trial-and-error' part of this whole process, finding the right DTB IMG.
Making it COMPLETELY noob-friendly and available to those without PC's just like the popular 'nix-on-droid' apps are, apart from this is native Linux, and not just proot/chroot.
What'cha think???

hi I am new in this forum, and I need someone more experienced than me to solve the problem of the my tv box (leelbox s1) (A53 Cortex S905X)  practically I cannot start his wlan0 because it cannot be seen by any of the image files in this link https://mega.nz/#F!j9QSDQSQ!6WpasOlbZYIInfw6yo4phQ!35ACSCjQ than to try other images from this forum ... but there is no way ... the driver of my wlan0 card is RTL871X ... someone tells me how can I solve ??? thank you.

The most straightforward way is to build the wifi driver yourself. You can follow the instructions in this post:

Hi all,

I have a p212 board (Scishion v88 Pro, 1GB RAM), running the Armbian_20.02.0-rc1.037_Aml-s9xxx_buster_current_5.5.0-rc6_20200205.img.xz image, with LXDE installed. I have one problem with it - when I switch the TV input to the box, and the graphic desktop is active, the box hangs - connected SSH clients freeze and tv shows "no signal". If a text TTY is currently active (ctrl+alt+f1), this doesn't happen.

I managed to get a syslog error logged when the system hangs, which I have included below. It doesn't matter if TV has CEC enabled or not. It looks like I may be able to work this around by disabling CEC on the box, but how do I do it? Also, would switching to another kernel fix the problem? Or maybe using the "desktop" image? It's really annoying and I haven't found anyone complaining about such a problem. Thanks in advance!

On version 5.3, it works.
why it does not work in 5.5?
I can't find exlinux.conf and uEnv.ini, what should I change? just uEnv.txt ???

Hi,

 

I've just setup armbian to run from sdcard on a NexBox a95x-B7N (s905x, 2G Ram, 8G Rom).

 

Running a minimal install for desktop (server image + Xorg, openbox and tools I use installed manually).

 

My issue is the X server runs at 1080p while hooked via HDMI to a 1440p@60 display (Dell P2416D).

xrandr does not detect any higher resolution than 1080p, and the edid doesn't show any either:

Yet, I know for a fact the monitor works perfectly at 1440p over HDMI (linux desktop connected to it works at proper resolution).

 

What am I missing ?

Any hardware limitations I am not aware of ?

Any hints where to look at or how to setup the resolution at2560x1440@60 ?

 

Thanks a lot !

You could try adding it manually. Here and example:
 

Add display resolution
----------------------
cvt 2560 1440 60                                                                                           Select the display resolution you want
# 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz
