Hello all!  I have successfully gotten @balbes150's debian server image installed onto a few H96's that I am setting up for compiling.  I am hoping to reclaim some of the memory that systemd is using.  Specifically, I intend to completely disable hdmi output as well as the reserved memory for the mali gpu.  Does anyone have a guide I could read for uboot or something else that would allow me to accomplish this?  I'm not looking for someone to just fix the problem for me, but a pointer in the right direction would be quite nice. :)  Either way, thanks go out to balbes150 and others in these tv box threads which have gotten me to this point.

Here was discussed a similar question (to increase the memory by turning off the redundant memory).

Is it perhaps because I'm running headless with a screen?

Gathered from the latest commit image stretch 4.9.40. Recorded on the USB flash drive, added the dtb (kvim2_multios.dtb). Has launched on the VIM2 Max. Connected only to a wired network, a USB flash drive with the system and USB power. Joined VIM2 via SSH from the PC and performed the initial configuration. After a reboot everything works. Try to run this image. Maybe when you build something made not so.

Well I'm puzzled, but maybe I'm doing it the wrong way coz' your image @balbes150 also doesn't boot with the same hang/error...

 

I'm doing the same as I have done when installing Armbian on my Khadas VIM Pros:

- Android on the emmc,

- Flashing aml_autoscript.zip with System update application under android,

- Burning the image on sdcard with Etcher,

- Sdcard in sd-slot,

- Power on

=> Boot Armbian from the sdcard

 

So have these steps changed for the VIM2 (or perhaps for all S905x/S912) ???

Thanks.

You forgot to add the correct dtb file (copy from the /dtb directory to the root of the first section and rename to "dtb.img").

Sorry I forget to list this step ;) but I have done it. For a matter of fact, I have tried all the dtbs for VIM2 with the same result...

I have this image running on VIM1 (s905x) and VIM2 (s912). What u-boot is installed ? To run the kernel 4.9.40 on VIM1 (s905x) need a new u-boot. I use my version of u-boot with built-in multi-boot.

To run from external media, you can use any option of the dtb. The correct option dtb important to install the system in eMMC. Then you need to use strictly correct dtb.

Well I've tried your image and mine on one of my VIM Pro: It boots without any issue (with the right dtb of course ^_^). I might say the images are not the cause of the hang on my VIM2 Max

Perhaps a stupid question and not related to my issue: Which revision of the VIM2 Max do you have? Mine is a V1.2 201707. I have spotted on Google V1.0 and V1.1 for the VIM2 and I don't know what might be the differences...

1. Try updating the multi-boot using only the image Armbian. To capture the image, copy and rename the dtb file, to run Android, to run multi-boot activation.

2. What firmware version is installed in the eMMC of your VIM2 ?

WiFi is now working on GT1.
 
1. Download & Copy AP6255 WiFi drivers extracted from Beelink's Android image:

 

Thanks for the instrutions - they did help me very much with the AP6330 onboard WiFi of the Sunvell T95K Pro
(S912 device = q201_6255):

Manually:
  

modprobe cfg80211
modprobe dhd firmware_path=/lib/firmware/brcm/fw_bcm40183b2.bin nvram_path=/lib/firmware/brcm/nvram_ap6330.txt

On boot:
  

# /etc/modules
cfg80211
dhd

# /etc/modprobe.d/options.conf
options dhd firmware_path=/lib/firmware/brcm/fw_bcm40183b2.bin nvram_path=/lib/firmware/brcm/nvram_ap6330.txt

lsmod: 

root@sunvell-t95kpro:~# lsmod
Module                  Size  Used by
brcmfmac              171742  0
brcmutil                5091  1 brcmfmac
joydev                 10336  0

aml_nftl_dev           95108  0

 

Now the WiFi does run very stable and without any big latency :)


Before I had used an external USB-WiFi Dongle from Edimax where I had a high latency :(
(and I did disable power-management in the /etc/network/interfaces)

Has anybody tried to build and run a mainline Linux kernel on a S912 device?

I do have a Beelink GT1 and would like to use a 4.9.x kernel, no graphics required for my headless server, just ethernet and maybe wifi for later. Currently I was able to boot the GT1 with an Armbian image from @balbes150, but this image has only a 3.14.29 kernel.

 

Any advice and pointers are really appreciated.

 

My friend, did you run the 4.9.x kernel on Beelink GT1? I'm trying to run more than not boot.

Asked balbes150 same question, but about Beelink GT1 Ultimate. It's only possible to rub 3.xx kernel on this device.

A new u-boot is needed to run kernel 4.9. I checked on my Tronsmart Vega S96 (S912) - with the dtb from VIM2 and the new u-boot system working with the 4.9 core.

Hardware: AlfaWise H96 Pro+

Armbian Version: Armbian_5.37_S9xxx_Ubuntu_xenial_4.9.40_server_20180204.img.xz

SOC: Amlogic S912

 

First thanks to all the people evolved in this great project :)

 

This is my first post here, I'm a newer armbian user :)

 

I'm using it has a headless server for my projects with docker and mongodb and my spring boot/aurelia framework projects,

and it works like a real server, without lags at all, simple awesome , my main objective is put my solutions in a economic/cheaper server :)

 

I already do that in raspberry pi 3, but I miss one important part that is use it has a Access Point with HostAPD like in RPI

 

Next the problem:

 

I Have problems configure Wifi card,

I cant use Wifi at all, and dont have wlan0


  

mario@amlogic:~$ dmesg | grep wlan0

mario@amlogic:~$ dmesg | grep wifi

I try everything that I remember, read a lot here in this post about wifi,

but I dont even know if my alfawise is working with wifi

 

I try all the DTBs from this armbian release one by one,

with modprobe, but nothing

 

  • gxl_p230_2g.dtb
  • gxl_p231_1g.dtb
  • gxl_p231_2g.dtb
  • gxl_p400_2g.dtb

  • kvim2_multios.dtb
  • kvim2_volumio.dtb
  • kvim_android.dtb
  • kvim_linux.dtb
  •  

I try to follow this post https://forum.armbian.com/topic/2138-armbian-for-amlogic-s912/?page=19&tab=comments#comment-49228

 

added wifi_dummy to /etc/modules

 

I even get driver from android firmware SCV4-Test1-Blue-PCB-H96ProPlus.zip

(the link to cfg80211 driver from above post is broken)

 

copied to /lib/modules/4.9.40/kernel/drivers/net/wireless/

 

and try to use modprobe on it like explained in above post

  

sudo modprobe cfg80211
modprobe dhd
modprobe: ERROR: could not insert 'dhd': No such device

but It never works, It seems I need help......i'm a bit lost now, without any wise idea of how I can configure wifi in this device

 

Or maybe I'm doing something stupid, or don't even know how to do it (I bet on this horse LOL)

 

The other problem is I cant backup my /dev/mmcblk0

 

always have the error `error reading '/dev/mmcblk0': Input/output error`

 

try many times, even try to use hard-disk and samba share but the problem is reading the mmcblk0

it always fail!

 

I try to backup, because I like to install armbian on mmcblk0

I dont need android, maybe in a near future, or when I like to sell it


  

$ sudo ddbr

nmtui can't scan networks/activate networks

 

I try manually play with device with  

$ sudo iw dev
phy#0
    Interface p2p0
        ifindex 7
        wdev 0x2
        addr 86:5d:d7:cf:32:02
        type P2P-device
    Interface wlan0
        ifindex 6
        wdev 0x1
        addr 84:5d:d7:4a:32:02
        type managed


$ iw wlan0 link

$ sudo ip link set wlan0 up

$ sudo ip link show wlan0
6: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    link/ether 84:5d:d7:4a:32:02 brd ff:ff:ff:ff:ff:ff

$ sudo iw wlan0 link

$ sudo iw wlan0 scan
(wait a 40sec and output nothing, it cant find any network, like nmtui ) 

seems like im playing with a wifi_dummy

$ sudo modprobe dhd
modprobe: ERROR: could not insert 'dhd': No such device

Maybe someone can help, I try hard, but it seems without some help I'm trapped here, cant use WiFi card :(

Hello Again

 

I use "modprobe wlan" and it "load" module and I can use wifi :) (Thanks Again)

 

but, after reboot, I must always do the same "modprobe wlan"

 

I put wlan on /etc/modules but it wont "load" wlan on boot

It only works with above combination, and launch "modprobe wlan" after boot/login 

cat /etc/modules
aml_nftl_dev
#wifi_dummy
cfg80211
dhd
# this is note loaded
wlan

Any idea is appreciated, thanks

 

Update: 

$ dmesg | grep wlan
