FriendlyARM NanoPi R4S
The NanoPi R4S is made by FriendlyElec for IoT applications. It includes the RK3399 SoC, two 1Gbps Ethernet ports, microSD storage, and either 1GB DDR3 or 4GB LPDDR4 RAM. The 4GB RAM version is recommended. The NanoPi R4S Enterprise Edition adds an additional EEPROM for the MAC address.
The R4SE adds onboard 32GB eMMC storage is not currently supported.
Supported Versions
Hardware Highlights
Installation
Decompress the OpenWrt ...sysupgrade.img.gz image and write it to a micro SD card using software such as dd or Balena Etcher. Then simply insert the SD card into the R4S, apply power, and it will boot OpenWrt.
See forum post for discussion and assistance.
1GB version - currently the 1GB RAM version is not bootable from snapshot. For this use one of the unofficial builds linked below:
Upgrading OpenWrt
List and export installed packages
Flashing via Luci gives the option to generate a list of installed applications for easy reinstall. However, this gets lost with an update in snapshot. To make sure you can re-install them afterwards, I'd recommend to make a list of installed applications like this:
opkg list-installed | cut -f 1 -d " " > /root/opkg_installed.tx
You may also attempt this process in Luci by installing and using luci-app-attendedsysupgrade.
Backup
Backup key directories such as: /root /etc before performing the sysupgrade.
Rsync: You can do this with rsync -rav /root /etc /mnt/sda1/router_backup/ (Where /mnt/sda1/router_backup/ is for example an external disk).
SCP: Alternatively, you can use the network with SCP: scp -r /root user@x.x.x.x:/path
LuCI Web Upgrade Process
- Browse to
http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/LuCI Upgrade URL - Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:
sysupgrademtd
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on for example 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
mtd
If sysupgrade does not support this router, use mtd.
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Debricking
Failsafe mode
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
CPU Management
How to Load Balance OpenWrt More explanation here but below are specific examples for the R4S.
To set processor affinity
#eth0 interrupts on core 0 echo 1 > /proc/irq/35/smp_affinity #eth0 queue on core 1 echo 2 > /sys/class/net/eth0/queues/rx-0/rps_cpus #eth1 interrupts on core 2 echo 4 > /proc/irq/87/smp_affinity #eth1 queue on core 3 echo 8 > /sys/class/net/eth1/queues/rx-0/rps_cpus
Your IRQ numbers might be different... you can find them with “grep eth /proc/interrupts”. First column is the IRQ, so replace those in the commands above. The number you echo into the file defines which CPUs to use. It's basically a binary number where each bit represents one CPU, then convert that to hex. Rightmost bit is CPU 0.
For example: Bits for CPU
00000001 > hex 1 > cpu 0 00000010 > hex 2 > cpu 1 00001111 > hex F > cpu 0,1,2,3 00110000 > hex 30 > cpu 4,5
Examples:
If you restart or change settings with SQM, it will reset the CPU affinity and you will need to re-apply settings.
Putting the commands in rc.local should work, assuming the IRQ numbers are somewhat static, which they seem to be. You may want to double check the IRQ numbers in /proc/interrupts and then do a reboot and check again to make sure they stay the same.
#eth0 IRQ on A53 cores echo f > /proc/irq/35/smp_affinity #eth1 IRQ on A53 cores echo f > /proc/irq/87/smp_affinity #eth0 queue on A72 cores echo 30 > /sys/class/net/eth0/queues/rx-0/rps_cpus #eth1 queue on A72 cores echo 30 > /sys/class/net/eth1/queues/rx-0/rps_cpus
If you want to get more fancy, you could get the IRQ with a command instead of hard coding it:
#eth0 IRQ
echo f > /proc/irq/`grep eth0 /proc/interrupts|awk -F ':' '{print $1}'|xargs`/smp_affinity
#eth1 IRQ
echo f > /proc/irq/`grep eth1 /proc/interrupts|awk -F ':' '{print $1}'|xargs`/smp_affinity
The grep command prints the line from /proc/interrupts, awk prints the first column which is the IRQ number, and xargs trims the whitespace.
Consider also this CPU optimization guide for more performance with affinity tuning.
Network interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| eth0 | WAN port | DHCP |
| eth1 | LAN port | static 192.168.1.1 |
Buttons
→ The FriendlyARM NanoPi R4S has the following buttons:

With console or internal USB2 tail attached, you will have to drill a hole in the side and modify the connectors as the case sits flush to the top of the Ethernet ports!
RTC
- RTC backup current is 27uA.
- Connector P/N: Molex 53398-0271
- 1.27/1.25mm RTC battery input connector
A bios battery will NOT fit in the case. You will have to drill a hole in the side and tape it to the side of the case externally, or mill/modify the case internally. Potentially milling part of the main heatsink and deepening above the ram chip would give enough space for internal RTC battery position.
5V Fan connector
- zh1.5-2a connector

Opening the case
Note: This will void your warranty!
Main PCB:
Remove all cables and the SDCard. There are 4 rubber/foam pads covering the screws. Remove them then unscrew all 4 screws. With the base removed, there are a further 2 screws holding the board into the case. Remove them and then tilt the case and tip the board out. It will NOT come out if the SDCard is still inserted. You may need to prise it out gently from the USB ports side if the heatsink pad sticks the board to the case.
