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.

Anti-Static foam sits beneath the boards and is surrounded by anti-conductive material.
One drawer down, 4 to go.

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'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!

Is there any way to get theses mini 5 inch capacitive touch screens to work on android i have a idea for a project but i cant spend to much money testing because im broke

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.

Did anyone tried that yet?

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

Hi everyone, this is my first post. I need any information about this board, whether it's a datasheet or a bsp
