Chose smal fan are vert noisy
I just bought some of these to play around with. I haven't had time to get to them yet, but I'm pretty excited about them. I did get the ones in the plastic case, but they do have the heat sink & fan.
Cool! I have one arriving in a couple days as well. I'm excited to see the awesome progress and reports from this thread. 
@jayanta525 I'm just getting caught up on this thread. I have a NanoPi R2S arriving early next week and I just stumbled upon the great work going on here for a mainline OpenWrt build. I just set up my build environment for this device.
This appears to be building from the snapshot branch as opposed to master-19.07--is that correct?
yes, from the master branch.
master-19.07 doesn't have the rockchip target.
I have rebased to the latest openwrt/master. Current commits are not tested, and should work as intended. I will create a stable release soon.

I tried your latest release on two R2S'es, but it seems the MAC address is hardcoded. They both end up having the same MAC address. Any chance you can fix this?
Thanks for sharing your great work on the NanoPi R2S!
Unrelated to your MAC address question, but did you try @jayanta525's latest pre-built release or did you build from his latest code in his repo? I am having trouble getting a working build from the latest code at the moment.
@wian I haven't got the time to test any of the builds personally, I have just received the board and got the time now. I will have all of those updates within a day.
@_FailSafe I recently forced pushed some changes to github, untested, that might be causing the issue. Fixing this ASAP.

Awesome! Glad you got your R2S!
I'll be patiently awaiting your updates and will be very happy to begin testing the next build.
@SvenH How did you manage to get SQM installed on release v1.2? When I try, it states kernel 5.4.48 is required and release v1.2 is at 5.4.42.
kernel bump to 5.4.48 no long ago, see here https://github.com/openwrt/openwrt/commit/e44e60b290fb346a4cdd5ca9b141abbcf61e80fe
Does this built of openwrt work with luCI support? Where tot download the lastest built?
Am thinking of buying this board to setup as router. Want to upgrade the Archer C7 who does 13/13 mbit with open vpn. Hope the VPN speed will be higher with this device. Heart AES is usable with this board
Sorry, I am aware of the kernel bump. My question is how you managed to get 5.4.48 built and onto your R2S. I am not able to get a working build of @jayanta525’s latest repo. I know it’s being worked on, and that’s awesome.
In the mean time, was just curious if you could share any tips about how to get onto a newer kernel than 5.4.42. The only feature holding me back from switching over to full testing of my R2S is lack of SQM.

SQM really is just a collection of scripts, so you can install it by hand from git you will need to make sure that all required packets/modules are available manually as well.
Approximately 24 hours after receiving my NanoPi R2S, I am now up and running on it in place of my OpenWrt VM!
General usage looks good so far, but it doesn't appear to be keeping up with layer_of_cake @ 400mbps down. I'm looking at various sources of information regarding IRQ balancing for this board, so hopefully with some tweaking I can get it running a little smoother at the top end.
UPDATE
So I realized BanIP was doing some initial heavy crunching during my speed testing earlier today. This little device is running layer_of_cake on my 400x20mbps DOCSIS connection just fine. I'm getting 420x23mbps without bufferbloat, just like I was with my 4 vCPU @ 3.4ghz VM. Obviously, my overall CPU utilization is higher on this device, but it's keeping up and has room to spare.
I switched over to the performance governor for a bit and ran some speed tests. I saw no discernible difference, other than temps being higher (~65c vs ~55c while not under 400mbps load). I am going to play around with that some more though. Also, as others have noted, it does seem that CPU0 takes the brunt of the load and I'm sure that's causing some bottlenecks.

UPDATE:
Date: 24th June 2020
Link: https://github.com/jayanta525/openwrt-nanopi-r2s
-
Repository has been updated with the latest source from OpenWrt master.
-
Added CI/CD example for automated builds with cache enabled
-
LAN: rtl8152 (eth1)
-
WAN: rtl8211E (eth0)
CI/CD Guide with CircleCi:
Link: https://github.com/jayanta525/openwrt-nanopi-r2s/tree/circleci
-
Install CircleCi free plan from GitHub Marketplace
-
Enable repository in CircleCi Projects
-
The initial build will be on the default branch with dummy configuration.
-
Switch to branch "circleci"
-
Edit feeds.conf to your requirement (specify commit hash values or new feeds)
-
Edit config.seed file to your requirements (leave the default configuration as is, contains openssl enhancements)
-
Edit custom script in scripts/ if required.
-
Commit the changes.
-
Build in CircleCi will automatically start (if configured correctly, check for orange dot next to commit in GitHub)
-
Cache is enabled, i.e. toolchains and packages will be cached for faster subsequent compilations (~20mins).
-
To clear the cache, change $CACHE value in .circleci/config.yml
-
IRQ_optimize initscript is added, check scrips/adjust-feeds.sh

You'll find the images in openwrt/bin/targets/armv8/
Issues
- You might come across a kernel config prompt (when verbosity is set), just ignore it with either Y or N, or you can build without verbosity to avoid this prompt.

@jayanta525 I am trying to build off your latest rk3328 branch (not doing the CircleCI yet) and run into an issue where the build just hangs fairly early in the process:

It's like it's waiting for an interactive response to the CRYPTO_SHA256_ARM64 algorithm and I have no idea why... any ideas?
UPDATE
I ran a make clean, make defconfig, make menuconfig and chose the Rockchip target and profile settings, then a make and run into the same hang with a "clean" config file. Not sure where to go next.

@jayanta525 Perhaps you'd want to add that verbiage to your last post so others don't chase their tails like I did.

Tomorrow i will get my r2s. Please tell me, i am pretty new to this, how to setup this on my SD card. Is there a manual available?
On my router (C7) i installed and configured openwrt as well and it is working great! Therefore i decided to start using this board
