@OleksandrK Would changing the symlink suffice? ls -ls /dev/rtc* 0 lrwxrwxrwx 1 root root 4 Aug 25 11:14 /dev/rtc -> rtc1 0 crw------- 1 root root 252, 0 Aug 25 11:14 /dev/rtc0 0 crw------- 1 root root 252, 1 Aug 25 11:14 /dev/rtc1 echo 'SUBSYSTEM=="rtc", KERNEL=="rtc1", SYMLINK+="rtc" OPTIONS+="link_priority=-100"' | sudo tee /etc/udev/rules.d/10-hym8563-rtc.rules This way both get loaded, but /dev/rtc is linked to rtc1 "hym8563".

On other platforms we can usually set an alias in the DTS for the rtc. On RK I'm not seeing that as an option, but what we can do is make it so one module loads before the other. In short, we set `CONFIG_RTC_DRV_HYM8563=y` and leave `CONFIG_RTC_DRV_RK808=m`. Which will force a hierarchy in the way things load. Case in point; patrick@nanopir3s:~$ dmesg | grep rtc [ 4.646223] rtc-hym8563 1-0051: registered as rtc0 [ 4.647295] rtc-hym8563 1-0051: setting system clock to 2025-08-25T01:34:16 UTC (1756085656) [ 5.548534] rk808-rtc rk808-rtc.5.auto: registered as rtc1 [ 5.605731] rockchip-drm display-subsystem: [drm] Cannot find any crtc or sizes [ 5.605810] rockchip-drm display-subsystem: [drm] Cannot find any crtc or sizes We may also be able to achieve this with a udev rule? I'll do a PR after further testing.

Before loading the module `sudo modprobe cfg80211`

Try the devel repo: https://github.com/lwfinger/rtw88

Why not do a PR and add the needed modules to the EDGE config?

Try the following: Armbian_25.8.1_Nanopi-r3s-lts_bookworm_current_6.12.41_minimal.img https://dl.armbian.com/nanopi-r3s-lts/Bookworm_current_minimal

Yes. I also used gnome-disks and didn't bother to decompress, as it is not required to do so. Which img are you writing exactly?

@OleksandrK I wrote both the Bookworm and Noble img and in both cases the partition table looked fine. I booted the Noble img; _ _ _ /_\ _ _ _ __ | |__(_)__ _ _ _ / _ \| '_| ' \| '_ \ / _` | ' \ /_/ \_\_| |_|_|_|_.__/_\__,_|_||_| v25.8.1 for NanoPi R3S LTS running Armbian Linux 6.12.41-current-rockchip64 Packages: Ubuntu stable (noble) IPv4: (LAN) 10.0.0.xxx (WAN) xx.xxx.xxx.xx IPv6: 2601:xx:xxx:a200::b05b, 2601:xx:xxx:a200:510c:3033:d120:7b0d (WAN) 2601:xx:xxx:a200:e489:6cce:bd44:57dc Performance: Load: 25% Uptime: 1 min Memory usage: 8% of 1.92G CPU temp: 30°C Usage of /: 10% of 29G RX today: 127 KiB Commands: Configuration : armbian-config Monitoring : htop Last login: Fri Aug 22 09:00:15 2025 from 10.0.0.36 root@nanopi-r3s-lts:~# As asked before, did you decompress the img before writing?

@twwn Add to rk3566-radxa-zero-3.dtsi --> snps,usb2-lpm-disable; https://github.com/armbian/build/blob/main/patch/kernel/archive/rockchip64-6.12/dt/rk3566-radxa-zero-3.dtsi#L495 &usb_host0_xhci { dr_mode = "peripheral"; + snps,usb2-lpm-disable; status = "okay"; }; See if it makes a difference. Information: https://www.kernel.org/doc/Documentation/devicetree/bindings/usb/dwc3.txt

Ur welcome.

Try this overlay /dts-v1/; /plugin/; / { fragment@0 { target = <&ehci0>; __overlay__ { status = "okay"; }; }; fragment@1 { target = <&ohci0>; __overlay__ { status = "okay"; }; }; fragment@2 { target = <&usbotg>; __overlay__ { dr_mode = "host"; }; }; }; sunxi-usb-host-mode.dts

Ok. So I think what I am getting out of this, is you are trying to use the designated PWR / OTG port as a HOST port. I'm not sure that is possible? I would need to investigate. Also I would be interested in knowing what ur u-boot log looks like powering it with that Waveshare.

@Samor140 I think, I'm missing a piece of the puzzle. I built a fresh Armbian IMG and I'm getting the same results as before. So maybe I don't understand exactly what you are trying to do? Which USB-C port are you trying to use here?

@Samor140 I just ran a basic test with a little hand held wireless keyboard+mouse combo and I can't replicate this. lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 002: ID 0413:0308 Leadtek Research, Inc.

Plus I've never heard anyone complain about it before. Could always see if there is a kernel update available or try the EDGE kernel. Most of the recent work I've been doing is related to EDGE "Bluetooth" and U-Boot. What are you powering the unit with? I haven't seen issue with this unit, but on other h618's I have had USB issues when not using a proper PSU.

@-jk- Yeah.... Well I've seen that before. Download, extract and put the debs you need on either a usb stick or sdcard. You can install with `sudo dpkg -i *.deb` Reboot and that should put you back to where you were. From there if you want functional BT, try the edge kernel. https://github.com/pyavitz/binary/releases/download/images/linux-image-current-sunxi64.zip EDIT: I attached the "Fix?" to this PR: https://github.com/armbian/build/pull/8454

Nice work. Looks good.

@-jk- Try the latest stable `edge` kernel.

I also have a personal preference. I don't like my fans just spinning to spin. I prefer them to trigger under heavy load and then cut off once that load has passed. You are more than welcome though, to make adjustments to it and submit them via PR.

That is exactly what it does. It would take a lot more work to make it gradually speed up, if it even could be done? Hence why I wrote it simply. The one I linked is the one you are using.

It is set to kick on at 55*C. You can review the dtso in the patch dir; https://github.com/armbian/build/blob/main/patch/kernel/archive/meson64-6.12/overlay/meson-g12-pwm-gpiox-5-fan.dtso

Brave browser supports arm64 and has a "New private window with Tor" option. Might be worth checking out.

Have you tried the meson-g12-pwm-gpiox-5-fan overlay?

For sure, no. It's a S905X5M https://www.hardkernel.com/shop/odroid-c5/ The C4 is a S905X3

HOST /dts-v1/; /plugin/; / { fragment@0 { target = <&usbotg>; __overlay__ { dr_mode = "host"; }; }; }; OTG /dts-v1/; /plugin/; / { fragment@0 { target = <&usbotg>; __overlay__ { dr_mode = "otg"; }; }; }; By default it is set to peripheral.

Chromium is not the best for playing videos. Try mplayer or mpv or something alike. I doubt you'll get great performance beyond 720p though. Might not even get it in some cases with 720p? If I wanna use an SBC as a media player, I either use LibreELEC or CoreELEC and don't use Alllwinner, but Amlogic. Good luck.
