Is there any dev working on the NanoPi R2S

you will need the dts files, I think this are the ones

I'd like to offer my help here. My R2S will arrive tonight. I can run test builds etc.

yeah, I'll try to prepare the image for it
btw, from my test wireguard is doing gigabit encryption and ssh aes is ~45MB/s

Where did you order & when ?

I ordered it on AliExpress from Shop4631030. $35 and it took 22 days delivery to Netherlands.

Here are some openssl benchmarks I did a while ago on this device if anyone is interested in its crypto performance: OpenWrt-based pihole alternative + more

i order from SmartFly Tech CO.,Ltd. aliexpress the Mar. 28 2020,
and it's still on the way

I have started to port to OpenWrt from armbian, since i don't have the device yet, i am unable to make any progress.

Reviews are welcomed.

Since i don't have the device yet, and can't confirm the code works. I won't push any commits to github.

Thank you.

Don't delete the repo yet, I was about to clone it and test on my device, lol

don't worry about that, i can provide you with test builds. It should be ready in 2 days.

I think you are missing u-boot dts files, also bl31 for 3328, please add it on top of the existing PR, also there are u-boot patches that prevent the need of python-dev and swig on the host machine

Can you check the UART output?

You have to switch RX and TX to get the signal.

I got UART output (on Windows, PuTTY) by setting the baudrate to 1500000.
For anyone debugging, I can recommend to start with a known good FriendlyWRT image to check your UART, then switch to debugging the OpenWRT builds.
With @jayanta525's latest build, I get to this:

U-Boot TPL 2020.04 (May 08 2020 - 15:03:18)
DDR4, 333MHz
BW=32 Col=10 Bk=4 BG=2 CS0 Row=15 CS=1 Die BW=16 Size=1024MB
Trying to boot from BOOTROM
Returning to boot ROM...

U-Boot SPL 2020.04 (May 08 2020 - 15:03:18 +0000)
Trying to boot from MMC1
spl: mmc init failed with error: -95
Trying to boot from MMC1
spl: mmc init failed with error: -95
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

It’s weird. Mine has output at 115200, only thing needed to do is switch RX and TX.

@SvenH, may I ask which usb to ttl are you using that support 1500000? I bought several yet none of them support that particular baud rate.

I use a CH340 device under Windows. With PuTTY, I get garbage at 115200 baud, but it works at 1500000. I got the number from

did you patched the uboot with your board dts, and it seems atf is not loading (bl31)

I have not done anything, I am just testing other people's builds. Let me know if there are other builds I can test.

I'm planning on buying the R2S and using it together a switch and an Ubiquiti AP, but i heard that the R2S runs so hot. Are you guys having problems with temps?
SQM should works flashely in this thing.
