NanoPI R2S is a great OpenWrt device

shensven · June 9, 2020, 8:20am

Everything looks ok, any plan pull request to upstream? @jayanta525

jayanta525 · June 9, 2020, 8:22am

Not yet, there's already a RK3328 target pending.

I'll update the PR asap, but anyway from experience, it will take a while to be merged

keiser1080 · June 9, 2020, 7:13pm

Hi all,

I will receive my 2rs tomorrow .
Could you explain how to build the openwrt image ans flash the sdcard?

https://openwrt.org/docs/guide-developer/quickstart-build-images
https://openwrt.org/docs/guide-user/additional-software/beginners-build-guide

This is a good start.

use https://github.com/jayanta525/openwrt-nanopi-r2s, gpio branch

xiaobo · June 10, 2020, 3:43pm

Build: 
git clone --depth 10 https://github.com/jayanta525/openwrt-nanopi-r2s.git
cd openwrt-nanopi-r2s
./scripts/feeds update -a
./scripts/feeds install -a
time make -j$(nproc) download V=s
make defconfig
time make V=s VERBOSE=1 -j$(nproc) JOBS=$(nproc) 2>&1 | tee build.log | egrep -i '(warn|error)'

Wating 30min build done.

Flash the sdcard:
cd bin/targets/rockchip/armv8
dd if=openwrt-rockchip-armv8-friendlyelec_nanopi-r2-rev00-ext4-sysupgrade.img of=/dev/<sdcard> bs=32M

flash sdcard done

Thanks.
I will try to build tomorrow under a docker containers, ans i will flash uder Windows.

I have order the rs2 31 euro, and i have pay here in Belgium the custom 38 euro

jayanta525 · June 10, 2020, 4:44pm

That's a total of 69 euro for the board.

Follow the procedure provided by @xiaobo with this modification

The build time will depend on your build system. It will take a while to build the toolchains initially and the subsequent builds will compile much faster.

I suggest you first try the pre-built images from here: https://github.com/jayanta525/openwrt-nanopi-r2s/releases

efsg · June 10, 2020, 5:13pm

It's not good!

cozuma · June 10, 2020, 5:29pm

You can avoid custom costs if you buy from aliexpress reseller. Should be about 40 euros with the case and power supply. Tip for next time .

cozuma · June 10, 2020, 5:43pm

crazy temp, i'm getting around 65°C now

jayanta525 · June 10, 2020, 6:49pm

I will look into the thermal issues soon as i get the board.

rk3328 SoC are known to run hotter, specially when set to PERFORMANCE CPU_GOVERNOR.

Try using an active cooler.

efsg · June 11, 2020, 12:52am

I customized the fan, but there problem

ced2git · June 11, 2020, 10:24am

Hi,

could you please share the spare parts you have used for the active fan

Do you use a second psu for the fan ?

Thanks

efsg · June 11, 2020, 10:31am

Fan connect motherboard
But I don't recommend it

ced2git · June 11, 2020, 11:12am

Hi,

why you do not recommend ? Due to current draw from the PSU ?

efsg · June 11, 2020, 11:17am

Too noisy!

ced2git · June 11, 2020, 11:32am

OK. It will sit in my basement So not an issue for me

efsg · June 11, 2020, 11:44am

But this is not as good as X86

xiaobo · June 11, 2020, 2:15pm

The NanoPI R2S metal shell has a good cooling(30-50 degrees Celsius) and quiet effect. Mine has been running for several weeks and is stable. The temperature is normal and there is nothing to worry about. 5 watt low power consumption.
