For more information about the RK3588 SOC and mainline Linux support, please see this document from Collabora.

Use a USB A-to-A cable, connect NanoPi-R6C to a PC as follows. Note: please pay attention to the USB port the USB cable is connected to in the screenshot.eMMC: This onboard 32GB eMMC flash serve as a bootable device to boot a Friendly-Elec-made OS. Running a system is made easier and more stable with this board. If your main network is IPv4, and NanoPi-R6C works in IPv6, the computer may not be able to connect to the Internet. It is recommended to turn off IPv6 (the method is described later in this WiKi), or switch the main route to IPv6; desktop] blur-radius=5:effect=blur:passes=1:separable=true:windows=4: FPS: 1800 FrameTime: 0.556 ms

I had connected the WAN port to a 2.5 GbE switch, LAN1 to the 2.5GbE port of the UP Xtreme i11 mini PC, and LAN2 to my laptop with a Realtek RTL8156BG USB 3.0 to 2.5GbE dongle. But somehow, LAN2 link would not go up. I naively believe FriendlyElec would provide an image where all three Ethernet ports would be configured, I initially thought there might be a problem with the hardware or the firmware image. fdab0000.npu: rknpu_ondemand / 1000 MHz (rknpu_ondemand dmc_ondemand userspace powersave performance simple_ondemand) Hello, everyone! I have been working on some experimental mainline Linux images using kernel 6.5.0 that I would like to share. Thanks to the open-source community for efforts to bring the RK3588 SOC to mainline Linux. cpufreq-policy0: ondemand / 1416 MHz (conservative ondemand userspace powersave performance schedutil / 408 600 816 1008 1200 1416 1608 1800) llvmpipe should mean software renderer. So I set the graphics to full screen and 1920×1080 resolution, and it was indeed unplayable at probably 1 or 2 fps confirming the GPU is not involved here. SuperTuxKart is supposed to work on OpenGL ES hardware, but I don’t know how to fix this.Type your device's ID (in our case it was "0BDA:C811" or "VID_0BDA&PID_C811") in a search engine and you may find a device that matches the ID. In our case the device we got was Realtek 8811CU. cpufreq-policy6: ondemand / 408 MHz (conservative ondemand userspace powersave performance schedutil / 408 600 816 1008 1200 1416 1608 1800 2016 2208 2304) Fix the problem that in some cases hdmi has no signal output and needs to be plugged in once to recover This single-board computer is designed to work well in industrial settings. Single-board computers made by FriendlyElec are known for their high quality and low price. Designed to withstand harsh environments, the NanoPi R6C is durable and robust. Additionally, it offers a wide range of features and capabilities that make it suitable for a wide range of applications. As an example, it can serve as a media player, NAS, mini router, and so forth.

On a PC which has the extracted RKDevTool_Release_v2.84 utility, go to the RKDevTool_Release_v2.84 directory, run the RKDevTool.exe file. If everything works, you will see a “Found a new Maskrom device” message on the utility; Add Ubuntu X11 desktop, based on Xubuntu, using panfrost driver for UI acceleration, rkmpp/mpv etc for video acceleration If the system in the eMMC, or the system in the TF card uses the first Loader type U-Boot TPL/SPL, it will always boot from the eMMC; fdab0000.npu: rknpu_ondemand / 300 MHz (rknpu_ondemand dmc_ondemand userspace powersave performance simple_ondemand / 300 400 500 600 700 800 900 1000)FriendlyELEC provides various images on the Wiki either booting from an SD card, installing from a MicroSD to the eMMC flash (aka eFlasher imagers), or flashing through USB with Windows tools. I like the eFlasher images since the OS runs from the internal eMMC flash and no special tools are needed. I had just used the FriendlyWrt eFlasher image, so I thought switching to the Ubuntu 22.04 eFlasher imager image would be a breeze. The results are pretty consistent between runs and I repeated the test later and got 17.1 runs per minute… The NanoPi R6C ships with FriendlyWrt (OpenWrt), but since I feel this specific model is better suited as a mini PC that happens to have router features, I flashed the latest Ubuntu 22.04 Jammy Desktop image from the Wiki (rk3588-eflasher-ubuntu-jammy-desktop-5.10-arm64-20230317.img).
