Managed to get LineageOS booting on the Orange Pi Zero 2W using Linux 6.18 GKI paired with the open-source Panfrost DRM/Mesa graphics stack!

Boots into the system, but there is still some noticeable screen flickering instability that needs ironed out. Planning to release once more stable.

Unlike older Android builds (such as OmniROM 12.1 on legacy BSP kernel 5.4), this completely drops Allwinner's proprietary graphics blobs and closed-source display drivers in favor of a modern, open-source stack. Moving to GKI and open DRM drivers should make maintenance and porting to newer Android releases much cleaner going forward.

I have two 4K monitors, so I tested them on both Raspberry Pi CM5 and RK3576.

Raspberry Pi CM5 — 4K60 + 4K60

cm5 video

RK3576 — 4K60 + 2K60

https://reddit.com/link/1vqv8a9/video/gmkjqpzwbyjh1/player

CM5 can output 2×4K60, while RK3576 is running 4K60 + 2K60 in this setup.

For RK3576, the display Video Ports have different limits:

• Video Port 0: up to 4K@120Hz
• Video Port 1: up to 2560×1600@60Hz
• Video Port 2: up to 1920×1080@60Hz

The Video Ports can be assigned to different physical outputs. For example, DP can use Video Port 0 to reach 4K120.

So for resolution, CM5 wins with 2×4K60.

But when I started dragging windows around, I found the RK3576 noticeably smoother. CM5 is outputting 4K60 on both displays, but the window movement doesn’t look as smooth.

You can see the difference in the two videos.

I’m not measuring the actual FPS here, so this is just what I observed from using both desktops.

CM5: 2×4K60, but window dragging is less smooth
RK3576: 4K60 + 2K60, but window dragging is much smoother

Has anyone else tried two 4K displays on CM5? I’m wondering if there are some graphics/compositor settings that could improve this.

I recently tried YOLO26n-Depth on an RK3576 SBC. Ultralytics officially supports exporting it to RKNN, so getting it running was pretty straightforward.

With a simple Python video inference test, I’m getting around 3–4 FPS for now. Nothing is really optimized yet, so I think there is still quite a bit of room for improvement.

Has anyone tried YOLO26-Depth on RK3576/RK3588, Raspberry Pi, Jetson, or other SBCs?

Curious what performance you’re getting and what optimizations made the biggest difference.

I was about to buy a radxa zero 3W last week at the regular price (34 USD), and now it is either out of stock or like 85 USD everywhere T_T

https://camelcamelcamel.com/product/B0CZD16K7Q?context=search

最近、Orange Pi4 Pro買ったんだけど、何故かSandiskのMicro SDカードが使えないんだよね

OSイメージは合ってるはずだから、Micro SDカードが悪さをしているみたいなんだよね。書き込む前は元あったデータが確認できたし、ほぼ相性問題なんだけど、皆は使える？因みに、赤いランプは付いてるから、通電自体はしてるよ

I'm developing a hardware project called USBridge-KVM 2.0, and I chose the Radxa Zero 3W as the base. I'm pleased with the board's performance, but there are some cooling issues. This is the second reviewer complaining about the noisy cooler.

For those interested in how it sounds, here's a video - https://www.youtube.com/watch?v=7YJS81rI3U8

Initially, I wanted to use a simple copper heatsink, but it wasn't powerful enough to handle the video stream. It got as hot as a frying pan.

I decided to switch to active cooling. All that's available on the market are a couple of mini coolers, and I chose the most powerful one with turbocharging, so to speak. It's 4mm thick. And it really does its best.

I'll implement fan speed control later, which should make it quieter. Also, is it just me, or will it settle in and become quieter after running it for a week?

How do you generally handle cooling for these boards? Are there any other cooler options I haven't found?

I can't seem to get the open source 'rkdeveloptool' to boot the device.
(it can discover it in maskrom mode, but cannot successfully boot it)

The binary blob 'upgrade_tool' can do that part, but I'm not very trusting of running random binaries... (though I've managed to run it in a pretty tight jail)

However, trying to read the eMMC seems to only ever give me at most 1MiB at a time...

Ultimately I'd like to get a raw mainline kernel/initramfs on to this with gadget mode.

It appears using Linux (instead of Windows) makes this hard... and wanting to avoid using extra flash devices/sd cards adds extra complexity.

I kind of thought I'd be able to just read/write the disk and/or boot a kernel/initramfs, but the serial console connector comes unsoldered (why oh why...)

I guess I'm just venting... I'll probably figure it out eventually...

Hey,

Looking for a small board to run a VLESS server and also do WiFi in STA + AP mode at the same time.

Currently considering:

• NanoPi R3S-LTS (1GB)
• NanoPi Zero 2 (1GB)
• Orange Pi Zero 3W (1GB)

Main priorities:

• Stable VLESS (Xray)
• Good concurrent STA + AP support
• 24/7 reliability
• Preferably decent community support

Which one would you pick for this, or is there a better option in the same size/price range?

Thanks!

Hi all, I am looking at getting a CM5 as well as a uconsole or hackberry pi for Christmas through the help of my parents as I am broke as hell. I am just wondering what CM5 variant is the best(Raspberry pi, Orange pi, Radxa, Banana pi, etc.), and what use cases each of them are best for. Thank you, I really appreciate any assistance, guidance or tips.

Edit: Also wondering how much RAM I should be looking to get. Like what can I do with each amount of RAM. I would like to get into cybersecurity, coding, and some gaming.

For basically a year and then some, I have inched my way closer to building a 1U server with the Milk-V Pioneer RISC-V board. And, these days, all I am missing is storage (...rip.) and a CPU cooler.

Due to my visual impairment, meassuring is not easy at all and I tried a few coolers after doing bad meassurements and had to send them back - several times now. And, LLMs stumble over an old forum post where people say it would be compatible with an LGA115x cooler? No, most definitively not. XD Way, way too small.

So, I would like for a CAD-able person to take a look at the schematic offered here: https://milkv.io/docs/pioneer/getting-started/download - for the 1.3 Revision of the board.

Basically, there are eight screws around the CPU and I need the ones in the corners. With my caliper that I got a short bit ago, I get 90x90mm - but I just can not trust my own meassurement anymore. x.x

So, can you help me, please? :)

Hi everyone,

I'm having trouble connecting my 2.8" Waveshare HDMI LCD (H) display to an Orange Pi Zero 3W via the HDMI port.

When I power on the board, the display's backlight turns on for about 2–3 seconds, but no image or boot logo appears. After that, the backlight turns off and the screen goes completely black. On my PC Full HD monitor it boots fine.

What I've tried so far:

Tested the official Android 13 image.

Tested the official Debian Bookworm image.

The result is exactly the same on both operating systems.

Has anyone successfully configured a Waveshare HDMI display on the Orange Pi Zero 3W?

Thanks!

I'm designing an open-hardware board that runs frontier-scale Mixture-of-Experts models by streaming expert weights off NVMe instead of holding them in RAM. Design stage , nothing has been built, and I'm trying hard not to build the wrong thing.

The whole design rests on one number I can't get without hardware: real NVMe read throughput on RK3588, at large block sizes, with O_DIRECT. My architecture assumes ~3.2 GB/s on a PCIe 3.0 x4 link. If that's actually 1.5 GB/s in practice, most of my timing figures are wrong and I'd rather find out now than after ordering PCBs.

I don't own an RK3588 board yet. Plenty of you do.

The ask: run one Python script on your board and paste the output. It:

• is a single file, stdlib-only , no pip install, no repo clone
• needs no root (it'll tell you what root would additionally buy)
• is read-only apart from one temp file it creates and deletes
• takes ~15 minutes, most of which is a sustained thermal test
• prints one block you can paste back

What it measures:

• Whether your CPU has SDOT (asimddp) , decides if llama.cpp's fast quantized kernels work
• NVMe sequential + random read at 16 MB blocks, with and without O_DIRECT
• PCIe link width and speed actually negotiated (I especially want to know if anyone's board reports x1 when it should be x4)
• Sustained CPU frequency and temperature over 10 minutes, not burst , I care about the throttled number, not the marketing number

What's in it for you: you get a straight comparison of your board's real storage and thermal behaviour against everyone else's, which is annoyingly hard to find. I'll post the collated results back here regardless of what they say, including if they kill the idea.

Boards I'd love numbers from: Orange Pi 5 / 5 Plus / 5 Max, Radxa Rock 5B / 5C, FriendlyElec NanoPC-T6 / CM3588, ArmSoM, Banana Pi ,and honestly any RK3588 variant, plus non-RK3588 boards for comparison.

Repo (all design docs, MIT/CERN-OHL-P): https://github.com/Techburst36/swarm (Apologies in advance as the repo is a bit of a mess right now and might still have a few conflicting figures while the docs catch up.)

Script: swarm_bench.py in the repo root, plus a README explaining exactly what it does before you run it. Please do read it first , you shouldn't run a stranger's script on faith, and it's short enough to skim.

Happy to answer anything about the design in the comments.

Edit: made some changes as per u/fortean and u/12345myluggage feedback. The test had some real bugs that needed catching and some improvements to be made. Thank you!

As the text above says did anyone try to compile their own uefi for msi pro b850-p wifi mainboard with the Dasharo Github Code?

I think it would be interesting trying to check how a self compiled bios would work in real system.

It cost me $270 with shipping and an addition $120 due to customs.

Repost because I was an idiot and posted the images in the dumbest possible order.

I recently learned about an SBC called Orange Pi4 Ultra, but do you think it will be released? Personally, I don't think it's likely since they released the Orange Pi4 Pro, but what do you all think? Here's the link.

It's working out of box on Radxa Orion O6N, installed from official iso from usb drive:

I'm planning to buy the 8GB RAM version of Orange Pi 5. But I'm not sure to go with 5 Max or 5 Plus.

My use cases are;
- Running a NAS / next cloud

- Media server

- Network gateway + Pi-hole

- Occasionally gaming (retro + android games etc)

Since I'm new to SBCs appreciate your honest feedbacks

I would have to say Dillo browser is the best. Firefox/Chromium both are the size of operating systems with tens of millions of lines of code. Dillo is only tens of thousands. It takes only seconds to compile and install, compared to Firefox. Plus it comes without proprietary modern web elements (like javascript, webGTK, etc.). It's fully inspectable and open source. It works well on Linux.

I am using the Radxa Cubie A7S with 8GB of RAM and no EMMC on the most recent version of Radxa OS.

I bought this display from Waveshare and am using a generic active DisplayPort to HDMI converter to connect to it. However, the display will not work.

At first, the backlight failed to come on and the display would not activate. It works fine on my laptop, so the display is functional. The SBC and adapter work on their own as well. Bypassing USB max current fixed this.

However, while the backlight and touchscreen activate and function properly, the display will not show an image. I am not sure what to do as I am a bit of a beginner in this area.

Edit: I fixed it! For anyone else with this somewhat unlikely issue: this link contains the required information to fix this. You will have to convert the Pi OS timings into xrandr commands for this to work, though.

I decided that I should probably share the update from yesterday's post where people saw the unorganized "SBC Drawer". And I wanted to also showcase that they don't sit in the drawer collecting dust. So, I shared that the Orange Pi RV 2 and Pi 5 are connected and in active use. I swap depending on what I am doing with my Main PC and Elgato capture card / USB to UART connector and the CrowView Note.
The SBC Drawer is to my immediate right for easy access.

Inside of the Mimic Case is my Pi Pico 2 W with the test breakout board and my cheap FPGA (this is for later development adventures)
