Help needed to use drivers of Wand-board dual in Ubuntu minimal root file-system

Hi I have downloaded Ubuntu Root filesystem from the following link.

wget -c https://rcn-ee.com/rootfs/eewiki/minfs/ubuntu-20.04.2-minimal-armhf-2021-04-14.tar.xz

It has no UI or window system.
So please help me to use the following features of Wand board dual.
They are Wifi, Bluetooth, Audio, Microphone, LAN, USB Host and OTG.

Is there any utilities/packages to use these features.

Please reply.

Correct, the default image is just a minimal image for all users to start as a base… If you want a full 2D/3D windows manager, keep reading the directions, specifically at the end:

Vivante GC320/GC880 (quad GC320/GC355/GC2000) 2D/3D Acceleration via [Etnaviv|https://github.com/etnaviv]
This sections assumes you have already installed your favorite xorg based window manager, such as lxde, lxqt, xfce, kde, gnome, etc… These are packages that need to be installed on top of your selected windows manager and an xorg.conf needed to correctly setup the video interface.

Regards,

Thanks Robert.

But still I need some more info.

When searched in the internet how to install those window manager I find like to issue commands

sudo apt-get update
sudo apt-get install package-xxx

and some other things to add repositories involving ppa so and so and then to issue reboot command.

My doubts are

  1. with this minimal root file system base is it enough to follow that instructions alone or I have to take extra care? if so can you please provide those instructions.

  2. As sudo apt-get need internet connection, how to enable that in this root file system
    I have one wifi antenna that can be connected to this board along with the enclosure.
    So can you please guide me how to turn on Wifi connection using the minimal root file system through command line. If Wifi not possible, how to turn on LAN connection(I have mobile hot-spot facility with me but for LAN connection I have to get it from neighbours,so only I am preferring instructions for Wifi enabling.)

  3. If sudo apt-get commands will not work with minimal root file system and if I have to get the files copied to SD card to the required locations after downloading and cross compiling in the host, Can you please provide instructions to install any of the window manager package?
    (I will be excited if I could install any of the window manager with touch support.)

As this kind of root file system is not prevalent, I am not getting enough help from internet.

Please reply.

Thanks.

Since the version of ubuntu you installed is Ubuntu 20.04, “any” guide for installing a built-in window manager such as xfce/lxqt/etc can be installed out of the box… You can use “tasksel” to have it install everything (will take lots and lots of space…)

I don’t remember if the minimal image contains wpa_supplicant, i’d advice you to use the ethernet connection first to setup your wifi connection. Remember this was a “minimal” image, it’s goal isn’t to shove one setup to every user, but a simple minimal image to build your custom setup on top of…

If something fails, it’s either something Ubuntu 20.04 didn’t support, or it’s broken… Just let me know, some things we can fix, other’s are just an Ubuntu thing…

Regards,

Thanks Robert,

I will try to use tasksel. And one more doubt, I have 16GB SD card with me now. Is it sufficient for installing Desktop environment using tasksel or should I go for larger memory size SD card such as 32GB,64 GB…

As I am going to execute tasksel from target if I encounter memory crunch during that process, it will crash.
That’s why I am asking before trying.

Please reply.

tasksel is a front end for a bunch of “*-desktop” meta packages, however it will not directly show disk usage…

Instead, you’d need to use apt… For example, if you wanted to install xfce, in ubuntu this would be:

sudo apt update
sudo apt install xubuntu-desktop

apt would then show how much disk space xubuntu-desktop

Regards,

Thanks for the help.

Also I saw a way in the the internet, to share my wifi connection to the board through LAN port of my laptop.

I am going to give a try for this.

Thanks & Regards.

Hi Robert,

I could not run sudo apt-get update command in the target.
I tried using minicom. It showed up as follows for some seconds

ubuntu@arm:~$ sudo apt-get update
Err:1 http://ports.ubuntu.com focal InRelease

And after that it showed like

ubuntu@arm:~$ sudo apt-get update

  Temporary failure resolving 'ports.ubuntu.com'

I followed the first answer of the following query

[type or paste code here](https://askubuntu.com/questions/1104506/share-wireless-internet-connection-through-ethernet-on-18-04-lts)

to share the internet connection to target using LAN.

In the target I checked the LAN configuration. It showed as follows.

ubuntu@arm:~$ ifconfig
eth0: flags=-28669<UP,BROADCAST,MULTICAST,DYNAMIC>  mtu 1500

Do you see any configuration is missing and that would be the reason for not sudo apt-get update not connecting to the server?
Or what else may be the reason?

Please reply.

Thanks.

Also tasksel was not installed in the target. so I had to use sudo apt-get update. and sudo apt-get install commands.

Well you lan connection on the WandBoard doesn’t have an IP address, thus no internet.

Either fix your Shared Connection, or connect the WandBoard directly into a network switch,

Regards,

Hi Robert,

I have configured the LAN connection of wandboard and PC as follows.

In wand board.

ubuntu@arm:~$ ifconfig

LAN connection in PC was configured to share the internet connection as follows.

I observe the same behaviour as before.
I dont know what else is missing. One difference I am seeing in the ifconfig output is Wifi is showing as
flags=4163<UP,BROADCAST,RUNNING,MULTICAST>
but ethernet in PC and wandboard RUNNING is missed.
flags=-28669<UP,BROADCAST,MULTICAST,DYNAMIC>

I don’t have sufficient knowledge in network configuring and usage. So please help me what I have to do.
Also when I configure these things as above my Laptop’s internet connection became unusable.

In the boot log of Wandboard I see like

 Starting WPA supplicant...
[  OK  ] Started System Logging Service.
[  OK  ] Finished Remove Stale Onli��…ext4 Metadata Check Snapshots.
[  OK  ] Finished Load/Save Random Seed.
[  OK  ] Started LSB: Start busybox udhcpd at boot time.
[  OK  ] Started Connection service.
[  OK  ] Started Telephony service.
[  OK  ] Started WPA supplicant.

WPA supplicant was started. Is it just a log or it is showing because it will be functional? I am using linux kernel 5.4 version.
If it is functional can I use that by command prompt in Wandboard. I have a Wifi antenna and enclosure.

Please guide me through.

Thanks.

Hi @ayyappanmuthu

Please post these:

sudo ifconfig -a
dmesg | grep brcm

PS, your ethernet port is active…

ubuntu@arm:~$ ifconfig

Note: I have not connected the wifi antenna and did not configure any IP address in the wandboard before taking this log.Is it right to take log as such?

Please reply.

Thanks.

Hi Robert,

Got some improvement. I am able to share the internet connection to wand board.

Earlier through nm-connection-editor I made ethernet port as shared to other computers and now when made that same to wifi interface additionally I am able to get internet connection in the wandboard.

Now I will try to install desktop and use for some time and if I find any issues I shall ask.

Thanks.

Hi Robert,

I have installed ubuntu-desktop by
sudo apt-get install ubuntu-desktop

and installation completed.

Then I issued
sudo shutdown -h now
command.
and I connected my Adafruit 5" display and powered up the board and display.
On boot up it showed wandboard logo and 2 penguin images and after that screen is blank.
Should I install xserver-xorg-video-armada-etnaviv and follow the instructions at the bottom of the guide in

to see the UI.

I have attached the boot log got through minicom in the host.

Can you please check and reply what might be the problem?

Thanks.

Hi @ayyappanmuthu if you want 2d/3d acceleration you must do:

sudo apt update
sudo apt install xserver-xorg-video-armada-etnaviv
#/etc/X11/xorg.conf
Section "Monitor"
        Identifier      "Builtin Default Monitor"
EndSection
Section "Device"
        Identifier      "Builtin Default fbdev Device 0"
        Driver          "armada"
EndSection
Section "Screen"
        Identifier      "Builtin Default fbdev Screen 0"
        Device          "Builtin Default fbdev Device 0"
        Monitor         "Builtin Default Monitor"
EndSection
Section "ServerLayout"
        Identifier      "Builtin Default Layout"
        Screen          "Builtin Default fbdev Screen 0"
EndSection

Regards,

Then can you please let me know what to do.
What kind of log I have to give to you to diagnose the problem?

Even in the minimal root file system I was able to use keyboard connected to wandboard usb port. Now I am seeing only black screen after logo.

hi @ayyappanmuthu well you installed ubuntu-desktop…

First check etnaviv loaded:

debian@arm:~$ dmesg | grep etnaviv

2nd check it’s running xorg…

cat /var/log/Xorg.0.log

If ubuntu-desktop setup “wayland” vs xorg, good luck! I don’t use wayland…
