Lichee Sipeed RV Dock RISC-V SBC: installing and configuring Debian

Lichee RV Dock RISC-V SBC: installing and configuring Debian

Things you need

  1. Lichee RV Dock

  2. USB-C power supply

  3. SD-card with minimum size 16GB

  4. Keyboard and mouse connected via one USB. I used a Logitech wireless-to-USB set. Maybe it works too via an USB hub

  5. Windows computer (or maybe Linux on x86, with wine & winetricks installed)

  6. Wifi network

  7. Monitor with HDMI, plus a HDMI cable


  1. Linux system to increase your disk size from 4 (8?) GB to something bigger

  2. An U.FL wifi antenna to improve your wifi signal

On Windows (or Linux x86 with wine?)

  1. Download the debian image 20211230_LicheeRV_debian_d1_hdmi_8723ds.7z from

    1. At moment of writing: the 7z file is 1.07 GB, and dated 2021-12-30 (hence the file name)

  2. Unpack the 7z file, so that you get an .img file

  3. install the PhoenixCard tool from

  4. Start phoenixcard.exe

  5. Insert an SD card, with minimum size 16GB into your Windows

  6. Select the .img file

  7. Select option “Start Up”

  8. Burn the Debian image to the SD Card. The PhoenixCard progress Status will quickly go to 40%, and then it will take 10 minutes to burn the image (depending on the size of the SD-card?). Alas the progress indicator will not show any progress until it’s completely finished

Someone reported it worked with wine on linux x86 like this:

  1. Install winetricks (on debian/ubuntu: sudo apt install winetricks)

  2. winetricks -q mfc42

  3. wine PhoenixCard.exe

After 10 minutes:

With your Lichee RV Dock

  1. Insert the SD-card into the Lichee RV Dock

  2. Connect HDMI and USB-C power

  3. The Lichee will boot. After a few minutes, you should see a mouse pointer, and then the full GUI

  4. You can log on with sipeed / licheepi

Hardware on the Dock

Setting up Wifi

If possible, connect an U.FL wifi antenna to the Lichee RV Dock. The U.FL connector (“IPEX”) is on the Dock, next to the small white 2-pin speaker connector and the USB-A connector

Note: I only got Wifi working when connecting to a password-less (so: open) Wifi access point within 1 meter from the Lichee RV. 

Set up wifi:

  1. From the start button, select Preferences -> Connman Settings

  2. Set Wifi from Disabled to Enabled. Strangely enough, each network will show twice. Possibly due to the two WLAN interface on the Lichee

  3. Select the Wifi network you want to connect to: click on the network, then Connect

  4. After that, check that you can “sudo ping” (yes, with sudo)

From the command line, the below can help

[email protected]:~$ connmanctl scan wifi

Scan completed for wifi

[email protected]:~$ connmanctl services

It seems Connman stores settings in


Like for example:

If you put the SD-card in another system, fdisk will show these partitions:

/dev/mmcblk1p1 contains Volumn

/dev/mmcblk1p7 contains rootfs

Enlarge the main partition without losing data

Warning: do the below carefully.

The default partition is 8GB, and only 4GB is available. To enlarge this partition without losing data, do this:

  1. Power off the Lichee

  2. Remove the SD-card and put into another Linux system

  3. Start gparted and in the upper right corner select the SD-card

  4. Remove the last, unused partition (partition #8)

  5. Select partition #7, and enlarge it, and execute that

  6. Put the SD-card into the Lichee again, and boot it



SSH access

You can access the Lichee via ssh. Again, login is sipeed / licheepi

Updating Debian

sudo apt update

sudo apt upgrade -y

The first time, the upgrade command will take an hour or so to complete.

The bad stuff: kernel oops

There is a kernel oops each 25 seconds.

Brute force solution:

sudo apt remove rtkit

… and the oops-es are gone.

Turn off annoying kernel oops messages on your ssh login

In the file /etc/rsyslog.conf, comment out the following line like this:

#*.emerg :omusrmsg:*

Reboot your system to take effect

Set timezone

/usr/bin/timedatectl list-timezones | grep -i amsterdam

sudo /usr/bin/timedatectl set-timezone Europe/Amsterdam

Disable graphical interface

If you don’t need the graphical interface (X, lightdm), and you want to save RAM, you can achieve that like below.

sudo systemctl isolate

More info on

If you can login to the system and have root access, you could use systemctl isolate to switch the system immediately to non-GUI mode, or systemctl set-default to set it as the default system state for any future boot-ups until told otherwise.

To switch back, use systemctl isolate to start the GUI mode immediately, or systemctl set-default to make it the default system state again.

The starts all network services, but omits the GUI subsystem. Many rack-mount servers run in that mode because they don't have any use for local GUI.

Add a swapfile

Note: I’m not sure this is a good idea on a SD-card

Shutdown / reboot

I learned to use the power symbol in the right lower corner, wait a few minutes, and it was going down.

(So, not good: “sudo reboot now”)

Documenation and URLs

Buy the Dock with wifi here (price ? 26,57, incl VAT, ex shipping) from the Sipeed shop itself:

(Sipeed shop )

Ubuntu image (with readme inside, including fdisk and dd instruction): from get licheerv_d1_1.14lcd_ub2004.tgz … I didn’t get that working, but someone else did.

Useful info on 

Very technical D1 documentation:

“In Nov. 2020, Allwinner and Alibaba’s T-head subsidiary announced an Allwinner D1 SoC based on T-head’s RISC-V-based XuanTie C906 core.”

CNX article from november 2020:

TTY interface

Heard (but not tested): the TTY interface is on the daughterboard, like in the figure below. Level should be 3.3V
