Can you give more details about the limitations of this NPU? I thought that they would be using shared system RAM. because all models are multiple megabytes, Can you comment about the ability to convert any model to your desired NPU target with "AI model conversion" https://tinycomputers.io/posts/rockchip-rk3588-npu-benchmarks.html (search for "Conversion Performance (x86_64)") Maybe its possible to run LCM-Lora in an armbian device, if it has 16GB. It is already running in a 16GB laptop without NPU or GPU. https://forums.raspberrypi.com/viewtopic.php?t=398225&sid=2b66e2cebe37506dd74215ead3dd264c I am thinking about buying an Orange PI zero 3W (allwinner NPU), but if you have troubles with a 6 TOPs NPU, I will have more troubles with a 2 TOPs NPU

Refer to the experiences here: I think someone wrote that the mainline kernel has NPU support. Is this NPU going to load only models that are in the Rockchip model repository?

Great job I don't have time to replicate this, but I would like to see more photos, screenshots, and what you can do with so many SDRs It's perfect to use an older kernel, if you don't need anything from a newer Linux (for example more stable Wifi, and resistive LCDs with Wayland)... In your writeup, you could have included the dmesg or journalctl messages, just prior to the crash. Sometimes, there's a confict between a new or changed kernel module and the module you want to use, and it causes crashes, or not being able to start Linux. Then you deactivate the module that gives you the problem. Which services were disabled with sudo systemctl mask systemd-networkd-wait-online ? It sounds like you never want to start a network service automatically on boot. I hope that the SoapySDR developers can fix the root issue, so that you don't need to lock a library .SO like that I made a thread showing how to control GPIO with Python gpiod https://forum.armbian.com/topic/33800-orange-pi-zero-3-gpio/#findComment-181191 Instead of using Opi.GPIO, which relies of sysfs (deprecated, and you can't use it in newer Linux)

I had no idea that there's an OpiZ3W Just in case, it is nothing at all like the Orange Pi Zero 3, which has a lot in common with the OpiZ2W. Yeely: what are your first impressions about this board? Are there demos for the NPU? Are the video encoders and decoders working with the Orange Pi Linux OS? Bring up verifiable (open source) examples of AI generated code, making an improved program.

The orange pi zero 2w is configured to only start u-boot from the microSD in the built-in microSD. You would have to: * recompile that uboot to load the initramfs and the kernel from your alternative storage (did you really mean HDD? which connector would you use?) or * load initramfs and kernel from the typical microsd /boot partition, but configure the kernel argument line to accept the HDD as the rootfs (make sure that the initramfs contains the kernel modules, and the hdd name is in the /etc/fstab file) or https://jamesachambers.com/orange-pi-zero-2-usb-ssd-boot-guide/

Does sway eat a lot of RAM? Can it be used fine in a 640x480 display? I've been staying with my labwc setup, because it's known to be minimalistic. Orange Pi Zero3 and Raspberries with 1GB RAM can run it fluidly.

Which kernel, debian, mesa and sway versions are running normally when you run a stock Armbian? Which new versions have you observed working together? (even if it's not ARM). If they are too different, they may not work together due to library functions expecting other parameters. You can try it with Ubuntu Noble, which has newer packages than Debian Trixie (build Armbian by yourself).

I am glad that it's possible to use a different ffmpeg version than what the distribution expects. (it gives me hope of installing it in Trixie, instead of changing over to the newest Ubuntu) Did you install the locally compiled ffmpeg at OS level, or did you keep it in a folder within your /home/username/...?

Usual User, the information you linked about Linux 6.19 seems like there's progress for Rockchip. However, is there any indication that Allwinner H618 could get H265/HEVC decoding acceleration working too?

Thank you for being specific about the RKxxx+6.19+Noble information As I asked in the other thread, please also specify which ffpmeg and mpv sources you used. I hope I can make it work in opiz3 (H618) in a more recent Debian (I only could make it work in Bookworm). Do you see any difference in 8bit vs 10bit HEVC(H265)?

For context, he is talking about: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20847 There are many ffpmpeg options. Which ffmpeg did you use? https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2request-v3 https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2-request-n8.1 And which debian/ubuntu version did you use? Which ffmpeg is included in that distribution?

Maybe this comment and thread have a hint for you https://forum.armbian.com/topic/47971-driving-the-ili9488-lcd-40-inch-cheap-chinese-clone/#findComment-229274 I don't own a waveshare LCD... but I would also like to know if its possible to make it work with Armbian

Can you repeat your amrbian OS version, Linux, and hardware? I can't give a confident advice for you, but have you tried: * extraargs=cma=256M in armbianEnv.txt * turn off compositor, if using xfce (others have suggested it, and I found it unnecessary) In mpv, turn on verbosity by adding -v to the command. Then while it is running, close it and copy all the mpv text in a text editor. Search for the words h264, ffmpeg, v4l2, hardware, software

Make sure you have ili9486.ko in your ko module folder: modinfo ili9486 Can you use the DTS that I published in: https://forum.armbian.com/topic/47971-driving-the-ili9488-lcd-40-inch-cheap-chinese-clone/#findComment-208446 But change the "compatible" line with waveshare,rpi-lcd-35 , Delete the stuff under the "compatible" line, until the "}vsync-len = <0>;", and replace it with what you had in your DTS. Change these lines, if they are different: spi-max-frequency = <24000000>; rotate = <270>; bgr; fps = <30>; buswidth = <8>; regwidth = <16>; Reference: https://github.com/raspberrypi/linux/blob/rpi-6.12.y/arch/arm/boot/dts/overlays/piscreen-overlay.dts
