BPI-W2: ubuntu 16.04 Install and run Node.js and http-server

  • insltall Node.js

After running Ubuntu 16.04, it’s easy to install packages on the W2. Please follow below steps to install node.js:

1.  apt-get install nodejs
2.  apt-get install npm
3.  npm install -g http-server
4. make a link to nodejs:  cd /usr/bin/; ln -sf nodejs node

then Node.js is ready on your system.

As a demonstration, I copied a 3D model to the W2 and displayed it with http-server. It runs very smoothly. Please refer to the video link below.


BPI-W2 new image : How to make and run the 64-bit ubuntu 16.04 on SD card

Hi, Did you have any problems making and running the 64-bit ubuntu on SD card? I followed all the instructions, but when I restart the BPI-W2 with the SD card, the HDMI monitor displays a green screen and freezes. With a serial session of Putty connected via a UART/USB cable, the Putty client displays the entire boot procedure, for which I have uploaded the Putty client session output. BootBPI-W2WithUbuntuSDCard.txt (145.7 KB)

Notice how the program, dmesg, continually outputs the following issue:

[ 100.794889] I/DC: [dc_wait_vsync_timeout 884] wait vsync timeout! vo_vsync_flag:0x00000101

Did you have this issue, or know what is causing it?

Thanks for any insights, Ed

Yes, HDMI can’t work on 64-bit ubuntu, we are working on this now.

Thanks for the update. How did you get ethernet to work? I can’t get that to work either.

I followed all the steps in section 5, and live ethernet cable is connected to WAN port, but I don’t seem to have internet connectivity

Network works fine, please ping to make sure your link is ready, then check the DNS next.

In order to establish network connection, I had to use the LAN port, not the WAN port, and modify the instructions as follows:

2. Ifconfig eth0 or eth1:
ifconfig eth1
3. Add default gateway to let the board can reach internet:
route add default gw
4. Add a DNS:
echo 'nameserver'>>/etc/resolv.conf
echo 'nameserver' >> /etc/resolv.conf`

’ ping works now, but when I execute step 5, ‘apt-get update’, it reports the following:

The process creates directory /var/lib/apt/lists/partial with user _apt and group root. There doesn’t appear to be a way to override this.
