research Rock Pi S, RK3308 CPU, is it supported by anything?

I pass the test from: https://github.com/armbian/testings/

Any additional information?

Thanks for confirming that it works. Focal images are also fixed and uploaded by now.

Well, its good that it works ... at all. I don't have this board so I can't test, but I am soon getting one. And it will be added to the autotest rig.

Downloaded and tested, but Focal 5.6 never boot. Etcher burned OK. Same microSD, same board, same power source, same Ethernet cable than Debian Buster.

I'm going to download again to double check.

Yes. Re-download and tested. Results uploaded. Also no Wi-Fi.

Anyone got the 8-channel audio input working? If so, I'd probably buy one to turn it into a budget sound interface

Kalobok · November 30, 2020

Just checked Armbian_21.02.0-trunk.4_Rockpi-s_buster_current_5.9.11_minimal image.
Wifi works, USB doesn't (lsusb gives no output).
Also, available frequencies are limited to 1008000, while with the legacy kernel max freq is 1296000.

Here's the report:

+BOOT=yes
+VERSION=21.02.0-trunk.4
+KERNEL=5.9.11-rockchip64
+NETWORK=NT
+WIRELESS=yes
+HDMI=NA
+USB=no

If you provide some guidance, I could try to check.

Do you recall if USB was working on older images? Around the 5.5/6 kernel?

USB works in buster 4.4.243.

Didn't check with 5.x kernels.

ashthespy · December 10, 2020

Yep, I have a feeling I never added the USB nodes to the device tree.

Similar story with the CPU, 1008000 is the max frequency in the upstream dtsi, but the 4.4.x kernel from Rockchip added higher 1296000 and some tuning that needs to be patched in as well.

It should be all be trivial, but I don't have a device to test right now.. If your willing to test, can show you what to edit and once confirmed, we can add the patches to the build system..

I can use armbian with kernel 4.4 for the moment, but I must compile the gpio-ir-recv module, it works
and I have a lot of lines "rc rc0: IR event FIFO is full!" in syslog. With armbian and kernel 5.9 this
module is present and works without these lines.
Perhaps a little effort to fix usb may be better.

ashthespy · December 16, 2020

Sorry, was a bit held up..
Basically you need phy: rockchip-inno-usb2: add usb-phy support for rk3308 and arm64: dts: rk3308: Add usb related nodes to dsti
and then the nodes @sbeaugrand added to the dts.

But it looks like this was fixed in https://github.com/armbian/build/pull/2461 and needs testing :-)

I am not really an expert - but is this a big issue? If it is, we can port the dts patches over from Rockchips's 4.4 kernel..

Not sure what is going on then, sorry I am away for the board right now to be of any debugging use..

Well, if it's possible, why not to include it? Especially that it's almost 30% increase in frequency. Since the board doesn't tend to overheat, there should be no thermal issues.

Also (and it's quite subjective, I admit), I have an impression that the board is somewhat slow when it has to generate web content for rpimonitor.

PS Tried usb with custom-built kernel - the same result (USB hubs are present but devices are not recognized).

hyp · January 5

Your usb patch is working for me. My conbee 2 stick was recognised succesfully. Hope it will arrive soon in stable build to get rid of the old kernel.

A patch for "normal" cpu speed would be nice to but for my use case its more a nice to have.

Same thing for me.

OK, One problem fixed, more to go Thanks.

Wi-Fi issues again

My Rock Pi S show me two Wi-Fi devices but the board only have one, the built-in interface.

Also the wireless connection is unpredictable sometimes shows SSH port sometimes not, sometimes I can find using the Avahi daemon sometimes not...

I uploaded the testing from armbian-config tool http://ix.io/2O1s

I also added an image from "nmtui"

Any ideas?

research Rock Pi S, RK3308 CPU, is it supported by anything?
