filemanager-http

If you are not concerned about security you could run a file manager using a web browser, and configure nanopi-r2s as a gateway.

just run :

ubuntu@nanopi-r2s:~$ sudo /usr/local/bin/filemanager-httpd

Configuring WAN (eth0)

You can configure your WAN interface as a DHCP, fixed IP or according to your service provider. Edit the file /etc/network/interfaces and change the eth0 configuration as desired, in my case i have DHCP (default):

  • Edit the file:

    sudo jed /etc/network/interfaces

  • File content

         # interfaces(5) file used by ifup(8) and ifdown(8)
     auto lo
     iface lo inet loopback

     auto eth0
     #allow-hotplug eth0
     iface eth0 inet dhcp

     #allow-hotplug eth1
     #iface eth1 inet dhcp
     auto eth1
     iface eth1 inet static
     address 192.168.1.1
     netmask 255.255.255.0
     broadcast 255.255.1.255    
     #gateway 192.168.1.1
     dns-nameservers 8.8.8.8 8.8.4.4

     #allow-hotplug wlan0
     #iface wlan0 inet dhcp
     #	wpa-ssid "foxy"
     #	wpa-psk "1234567890"
     #address 192.168.254.55
     #netmask 255.255.0.0
     #gateway 192.168.254.254
     #dns-nameservers 8.8.8.8 8.8.4.4
     ####wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
     # Disable power saving on compatible chipsets (prevents SSH/connection dropouts over WiFi)

     #wireless-power off

Client connection (DHCP)

A Linux desktop connected to the LAN interface of our mini router to surf the internet.

v0.3 - Mini Router NanoPi R2S with eth-monitor

Kernel updated to 5.4.28 with eth-monitor to display the eth status for the WAN and LAN interface. When the WAN is up, the WAN led will be ON, when down, WAN led will be OFF.

https://github.com/avafinger/nanopi-r2s-ubuntu-server-minimal-image/releases/tag/v0.3

v0.4 - Mini Router NanoPi R2S with eth-monitor

Kernel updated to 5.6.2 with eth-monitor to display the eth status for the WAN and LAN interface. If WAN is up, the WAN led is ON, if down, WAN led is OFF. Same for the LAN interface.

eth-monitor runs as service. You can stop, start or see the status of the service.

  sudo systemctl status eth-monitor.service
  sudo systemctl stop eth-monitor.service
  sudo systemctl start eth-monitor.service

https://github.com/avafinger/nanopi-r2s-ubuntu-server-minimal-image/releases/tag/v0.4

v0.5 - Ubuntu 20.04 LTS Server with Kernel 5.6.5 (Experimental)

Our mini router is kind of slow on the iptable NAT routing/fowarding and i can't find a way to optimize it or don't know how to do it. For this reason we will try the Ubuntu Beta version and see what we can get, all from scratch. In my experiments, the routing and forwarding is 8x slower than using the Gigabit port directly, maybe the NAT rules are overkill somewhere.

Add Initial support for rtl8822bu with Ubuntu Focal, the smallest Image size i could get, just for evaluation on RK3328 boards.

Ubuntu Focal 20.04 LTS Server

https://github.com/avafinger/nanopi-r2s-ubuntu-server-minimal-image/releases/tag/v0.7i

  • Burn SD Card with etcher or Win32DiskImager

  • Use 7z to unzip

  • boot with this Img and login with: ubuntu / ubuntu

  • resize rootfs manually or try resize_rootfs.sh to reclaim all space in the sd card after login, issue the command in the shell:

    sudo chmod +x resize_rootfs.sh
sudo ./resize_rootfs.sh

v0.7s - Boost to 1.5 GHz

It is safe to boost the NanoPi R2S to 1.5 GHz.

v0.95 - Kernel 5.8.0

Mainline Kernel 5.8.0 built on-board with gcc 9.3 to ensure it is really stable. Build was done with the yellow case. Thermal throttling has been adjusted to hit at 80ºC , so if you plan to use intensive cpu applications the board can reach 80ºC and scale down to 1.3 GHz, can also reach 85ºC really easy but will scale down to 1.2 GHz or even 1 GHz. During the kernel build with 4 cores 100% the board was running with 1.3 GHz most of the time.

Controlling FAN speed control with pwm0

We are going to build a service to control the fan speed according to the cpu temperature. Mainline kernel has exposed the pwm0 where we can output voltage from 2.6v to 5.0v and control the fan speed.

Enabling the pwm0

sudo su
echo -n 0 > /sys/class/pwm/pwmchip0/export

pwm0 is now exposed as /sys/class/pwm/pwmchip0/pwm0

Source code for the tiny systemd service is available here: https://github.com/avafinger/fan-speed-control

At startup, the pwm0 pin drives 5v and make Fan full speed. The service will check the CPU Temp and try to drive the speed of the Fan, so the noise is minimum, or should be.

The service has been tested with good results with the snowfan that comes with NanoPi M3.

v0.99 - Kernel 5.10.0 (RC1 / RC2)

Testing the Kernel 5.10.0-rc1 (confirmed LTS ?) for NanoPi R2S. Currently working:

  • eth0
  • eth1
  • DVFS
  • pwm0 (fan)
  • halt && reboot (halt )

After some testing, the shutdown command still not working and you need to use:

sudo halt

NanoPi R2S htop Kernel 5.10.0-c1

Boot Info

When you turn ON the board, the 3 leds will go ON for a few seconds and later WAN and LAN leds will show the status link.

Latest Kernel - NanoPi R2S mini router - Ubuntu 19.10

Linux nanopi-r2s 5.6.1 #2 SMP PREEMPT Thu Apr 2 19:50:55 -03 2020 aarch64 aarch64 aarch64 GNU/Linux

Status

  • eth0 (ok)
  • eth1 (ok)
  • DVFS (ok)
  • eth link status monitoring (ok)

Cpu / Kernel Health

Checking the board health (manually)

  cat /sys/devices/virtual/thermal/thermal_zone0/temp
  38181
  cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

Interface monitoring

Kernel has support for leds so we can control the available leds on the board.

sudo su
cd /sys/class/leds/
root@nanopi-r2s:/sys/class/leds# ls
lan_led  status_led  wan_led

The available options are:

  [none] rc-feedback rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock mmc0 timer oneshot heartbeat gpio cpu cpu0 cpu1 cpu2 cpu3 default-on panic

  • To turn on the wan_led

    echo "default-on" > /sys/class/leds/wan_led/trigger

  • To turn off the wan_led

    echo "none" > /sys/class/leds/wan_led/trigger

We can now move on and install a service to show the status of our WAN and LAN interfaces turning the wan_led and lan_led ON and OFF.
