Introduction


I managed to have a working Debian desktop environment on RISC-V after previous test and some exchanges on different Sipeed/D1 channels. Most informations are today available on Linux-SunXI.org Wiki dedicated page.

See also the previous article Booting Ubuntu Linux on a LicheeRV.

The main problem was to have a working imaage with Debian, AllWinner and Speed give only a Linux image that can be made on Windows using PhoenixCard tool………

Someone of a Sipeed chat that have access to a Windows installed computer, made the conversion and give it available here (my mirror copy) sha256sum of the image: cf73baf3ed67d480e7606c666ccb81fce21295ba8fbba10e0ad86939065be6ffw. You need an at least 16GB microSD card to use it with LicheeRV and it’s Dock..

Installing the Image

To install it, you can follow the following steps:

Install aria2 (Debian based (Debian, Ubuntu, …) sudo apt install aria2, Archlinux based (Arch, Manjaro, …): pacman -S aria2)

For an USB microSD card reader (I use /dev/sdd for /dev/sdX in my case you can verify which one is your by sudo fdisk -l:

DEVICE=/dev/sdX
aria2c https://popolon.org/depots/RISC-V/D1/images/LicheeRV/20211230_LicheeRV_debian_d1_hdmi_8723ds.ddimg.xz.metalink
xzcat 20211230_LicheeRV_debian_d1_hdmi_8723ds.ddimg.xz >20211230_LicheeRV_debian_d1_hdmi_8723ds.ddimg
dd bs=1MB status=progress if=20211230_LicheeRV_debian_d1_hdmi_8723ds.ddimg of=${DEVICE}

Then delete the partition 8:

sudo fdisk ${DEVICE}
d
8
w
q

Resize the partition 7 to use the remaining space:

sudo parted ${DEVICE}
p

You will see the exact size of your partition (here in bold) that will be used later:

Model: SD ACLCE (sd/mmc)
Disk /dev/mmcblk0: 63.9GB
(parted) resizepart 7
End?  [??.?GB]? 63.9GB
(parted) quit

Then now grow the fs itself.
* for an USB sdcard reader (/dev/sdX):

sudo resize2fs ${DEVICE}7

* for an internal sdcard reader (/dev/mmcblkX):

sudo resize2fs ${DEVICE}p7

Now sync (flush data in memory on disk) the card:

sync

You can now extract the card from your reader and put it in the LicheeRV board.

Booting

H2MI to DVI and HDMI to USB dongles I used
Then boot it plugged on a 1080p HDMI screen. It doesn’t work with my HDMI->DVI (tried on a 1680×1050 DVI-A and a 1080p DVI-D) or with my 1080p HDMI->USB dongle. Someone else reported it worked with an HDMI-DVI dongle.

You can see the whole boot sequence by connecting to UART. See this ASCIInema record of the boot sequence (local copy of the cast).

LigthDM connexion prompt

At the LightDM Login and pass prompt use:
* Login: sipeed
* Password: licheepi

Then you will have after about less than 1 minutes (yes, that’s a bit slow) the desktop.

Setting the WiFi

You can set your WiFi connexion (and even BlueTooth) with connexion manager. It is accessible from the main menu (the most left-bottom gray icon) by Preferences > Connman Settings, see this picture

access to Connman from menu

Then choose Wireless at left of the new box.Activate the Wifi connexion in Connman
* Click on the gray button to start the wifi (1 in red on the picture).
* Select the network you want to connect to (2 in red)
* Click on connect (3 in red).
* A prompt will open, where you will need to enter the passphrase of the WiFi.
Authentication required

The connexion should be established now, with « Connected » wrote at top of the window and « Online » beside the name of the Wifi router name (as on the picture at right.

You can by pressing on the gear at the right of the router name (2) in previous right picture, have access to some control to have the connexion set automatically at each boot.

click on the grayed autoconnect button, it should become blue meaning autoconnect is activated

Click on the IPv4 at left and then on the Method (set to None) button, choose automatic in the menu as shown in the following picture, then apply at bottom right.

I noticed it worked better if I uncommented the following lines in /etc/network/interfaces using

sudo vi /etc/network/interfaces<

, it seems to work far better when it's uncommented (there is a typo: wpa-deriver instead of wpa-driver, but works as is. to remove the # comments, just move the cursors to them and press x one time.

auto wlan0 #(wlp3s0 为网卡名)
iface wlan0 inet dhcp
	wpa-deriver wext
 	wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

When finished, quit and save with the sequence of keys: ":", "x!", ["enter"] key

You can sync your card and reboot safely now:

sync
sudo reboot

It should work fine the next time. you can verify the ip address on your router, or by connecting on the console or interface, and typing:

sipeed@sipeed:~$ ip address
1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: sit0@NONE:  mtu 1480 qdisc noop state DOWN group default qlen 1000
    link/sit 0.0.0.0 brd 0.0.0.0
3: wlan0:  mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 74:ee:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 192.168.xx.xx/24 brd 192.168.xx.xx scope global dynamic wlan0
       valid_lft 41822sec preferred_lft 41822sec
4: wlan1:  mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 76:ee:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 192.168.xx.xx/24 brd 192.168.xx.xx scope global wlan1
       valid_lft forever preferred_lft forever

or, like the former way:

sipeed@sipeed:~$ sudo ifconfig
[sudo] password for sipeed: 
lo: flags=73  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10

        inet 192.168.xx.xx  netmask 255.255.255.0  broadcast 192.168.xx.xx
        ether 76:ee:xx:xx:xx:xx  txqueuelen 1000  (Ethernet)
        RX packets 582  bytes 80736 (78.8 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 504  bytes 82357 (80.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

To be more comfortable I suggest to make a swap file on the microSD if you want to use some desktop application, because, 512MB is really short:

Create a swap file of 1GB (1024M) and format it:

sudo dd bs=1M count=1024 status=progress if=/dev/zero of=/swap
sudo mkswap /swap

Add this to /etc/fstab for automatic mount after reboot:

echo "/swap none swap defaults 0 0" |sudo tee -a /etc/fstab/

Then mount it imeediatly

sudo swapon -a

Among application working well, I found:
* graphic tool: GIMP, Krita work a bit slowly. The first time, need to wait long time, and then go to preferences to disable GL acceleration before creating an image, else it will be awfully slow. Everything will go far faster after that.
* Animation tool: Pencil2D
* IRC client hexchat, and Telegram-desktop client
* Blender work but is totally unusable
* Web browser are generally unusable, the exception is Netsurf (package netsurf-gtk, see screenshot below), that is still slow but a minimum usable, a framebuffer version (netsurf-fb) is pre-installed, but should be used in terminal console view, that is not setup by default. Text browsers like w3m, elinks, etc, can work. Firefox is unavailable (there is an unofficial method to patch it and compile it for RISC-V, need to test it, but I doubt it will be efficient, a 3 or 4 year old version, could be better. There is an official patch but seem to be no more available? As often, Firefox like to block progress on new technologies....

Netsurf-GTK has little display bugs, but is fairly usable:

Image NAND stable de Debian pour Cubieboard2

Lors de mes premiers tests systèmes de la Cubieboard2 aux alentours d’octobre 2014, l’accès à la mémoire flash NAND intégrée ne fonctionnait pas avec le noyau et pilote à sources ouvertes. C’est corrigé depuis au moins la version 3.4.79 du noyau adapté par la communauté Linux-Sunxi. D’avantage d’optimisation importantes vont apparaître durant cet été (utilisation des DMA pour les transferts entres composants, utilisation de l’unité crypto/CRC pour le chiffrement, etc…).

Après avoir testé différentes images NAND, Cubian, lubuntu-desktop, etc… j’ai enfin trouvé l’image NAND d’un système stable, appelée Debieez cb2, basé sur Debian Wheezy (8.5, la dernière stable).
