Linkstar H68K is a Rockchip RK3568 multimedia router with two 2.5GbE ports, two Gigabit Ethernet ports, an optional WiFi 6 and Bluetooth 5.2 module, a few USB ports, and an HDMI 2.1 port supporting up to 4Kp60. Rockchip RK3568 was initially introduced as a solution for NVRs, but I’ve yet to see any, Instead, we’ve gotten some SBCs and mini PCs, as well as several routers such as NanoPi R5S, FastRhino R68s, and the upcoming Radxa E25 that will be announced next week. Linkstar H68K specifications: SoC – Rockchip RK3568 quad-core Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G52 MP2 GPU, 0.8 TOPS AI accelerator, 4Kp60 H.265/H.264/VP9 video decoder, 1080p60 H.264/H.265 video encoder System Memory – 4GB LPDDR4X Storage 32GB eMMC flash MicroSD card socket Video Output – 1x HDMI 2.1 port up to 4Kp60 Audio – 3.5mm audio jack, digital audio via HDMI Networking 2x 2.5GbE RJ45 [...]

H68K is right! But i thought the producer was a company located in Hongkong called Hinlink.
It does not look like a new box for me. I found this Router on Taobao. But selled it on "Parcel Up".

There are already videos on bilibili and youtube.

This is the side of Hinlink:

I get my information from:
https://www.wifilu.cn/2442.html

But its good that Linkstar made a translated manual ... . But I do not like the Linkstar Brand -> the original box is blank without LOGO.

The Software is already out:

I think we western guys and girls have a problem! Because there are videos of this Box on bilibili from 2022.08.06. But everyone was talking about the NanoPi R5S. Nobody talks about this Router Box.
It looks like that the globalized world that I thought I would live in does not exist.

I've built a image for this board: https://github.com/amazingfate/armbian-h68k-images, based on 5.10 rockchip legacy kernel, supporting panfrost gpu driver and hardware accelerated Kodi.

@amazingfate Mine just showed up in the mail today and I loaded your image onto it. Worked great right out of the box. Many thanks!

Just going to convert it to headless for my needs

 

 

Sorry for necro, but I believe this may still be relevant.
Tested the image by @amazingfate with H68K running as my main router with heavy IO load (Gigabit fiber and home server running NAS and some virtual machines for various services which include multimedia streaming and torrents). While overall the system itself is stable, there are several major issues with networking:
* ETH0/ETH1 ports (Rockhip GMAC RTL8211F @ 1Gbps)  cause insane ksoftirqd CPU load, especially when both ports are under load. This results in packet loss under heavy load. With one port used, the CPU usage is tolerable. But the system still can't max out a gigabit link, topping at 500-600mbps. I use one port for internet upstream.
* ETH2/ETH3 ports (PCI-E RTL8125 2.5G @ 1Gbps) work well... when they work. In my setup, one port provides upstream to a home server while the other provides upstream to all other devices via a 16-port managed switch (which has other switches daisy-chained - most of my network is wired). The switch-side port likes to disconnect by itself at random intervals for 4-5 seconds and then come back. The home server-side port does not do that but it too sometimes likes to just stop working with no errors (fixable by a soft-reset). Swapping ETH2/ETH3 connectors "swaps" the misbehavior. This makes me believe the misbehavior is directly caused by IO load, not specific interfaces.

Other minor issue is the front LEDs which aren't properly setup in the DTB file. Recompiling the DTS from kernel sources with all 3 LEDs added (GPIO assignments taken from Seeed's OpenWRT fork DTB) fixes this. Not a big deal though.

Upgrading the r8125 module to the latest version does not help. There's a 6.1 kernel available which should work with the RK3568 SoC (sans the multimedia stuff which I don't care about) but I do not have a working DTB file to test it.

Next thing I'll do is take the device apart to check it's cooling setup to rule out any possible overheating issues with the RTL8125s.

does anybody have dtb file for h68k v2 mainly for NPU support?
