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.

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
+DVFS=NT
+ARMBIANMONITOR=http://ix.io/2G2R

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

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..

Yes, I'd like to test, please provide me instructions.

For usb, I try this:

I forgot this:

  Reveal hidden contents

And I fixed this : cp ../armbian-build/config/kernel/linux-rockchip64-current.config .config
But again no device found.

  Reveal hidden contents

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, thanks for the hint.

 

USB hubs are now available:

anton@rockpi-s:~$ sudo lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But USB devices are not recognized.  

 

Also, max frequency is limited to 1008000

anton@rockpi-s:~$ cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies

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).

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.

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?

Rockpi S is not supported and the last release is on 26-Aug-2021.
I have tested armbian 22.08 with bullseye and kernel 5.18 (edge), and it works. My usage: ethernet, usb, audio dac lineout, ir, i2c, spi, gpio.
With kernel 5.15 (current), module snd_soc_rk3308 is loaded, but there is no audio device.

How to build on debian with cross compilers installed :
  

df -h .  # 6,5G needed
git clone https://github.com/armbian/build.git armbian-build
cd armbian-build
sudo apt install debootstrap
sudo modprobe loop
systemd-run -p CPUQuota=$((`nproc`*50))% --scope bash -c './compile.sh BOARD=rockpi-s BRANCH=edge BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no CLEAN_LEVEL=, RELEASE=bullseye SKIP_EXTERNAL_TOOLCHAINS=yes'
cd output/images
ls -l Armbian_22.08.0-trunk_Rockpi-s_bullseye_edge_5.18.5_minimal.img
-rw-rw-r-- 1 root sudo 1061158912 19 juin  21:16 Armbian_22.08.0-trunk_Rockpi-s_bullseye_edge_5.18.5_minimal.img

I realize that the Rockpi S is no longer officially supported.

Why was it dropped?

 

My application does not require audio.

What are the other problems with this board?

I like it because it draws only about 600mW, has built-in Ethernet and 2 USB ports.

 

The last release that supported it [Armbian 22.05] seems to work reasonably well for me.

WiFi, LAN and USB were OK.

SD card works but I could not access the SD flash (4-bit wide EMMC)

 

Running the build instructions posted by sbeaugrand on June 20 now...

 

Any insights appreciated!

Hi Brent,

We don't have a maintainer for this board and we have no budget for development.
If you want to get involved and maintain the Rockpi S, then Armbian is the ideal platform and it would be great if you could to join the team.

https://docs.armbian.com/User-Guide_Board-Support-Rules/

https://www.armbian.com/newsflash/armbian-needs-your-help/

The board is community supported, so you could build an image using the Armbian Build system: https://docs.armbian.com/Developer-Guide_Build-Preparation/

sbeaugrand's post above says that armbian 22.08 with bullseye and kernel 5.18 (edge) worked.  That's a current build.
 

Or you could try some images from the archives: https://www.armbian.com/rockpi-s/#kernels-archive-all

SD NAND device working!

 

The RockPi S is optionally fitted with an "SD nand" chip.

Near as I can tell, the SD NAND is just an EMMC limited to a 4-bit data bus.

The file rk3308-rock-pi-s.dts has this EMMC defined with status: "disabled"

I merely changed it to "okay" and, voila, the SD NAND works!

 

The odd thing is that the unmodified u-boot has no trouble accessing the SD NAND,

even though the SDnand is also "disabled" in u-boot's dts files.

 

Question:

  I don't have a RockPi S without the SDnand chip.

  If someone does, could they verify that "enable"ing the non-existent part doesn't cause a kernel crash or hang?

  Also, what is your u-boot doing with the missing SDnand device?  Do you see two mmc devices or one?
