Armbian v25.5: Expanding Horizons, Honoring Community, and Powering the ARM Ecosystem The Armbian team is proud to announce the release of Armbian v25.5—a significant update that reinforces the project’s commitment to delivering a reliable, high-performance Linux experience for ARM-based devices. This release highlights continued progress across the system, including deeper hardware support, enhanced tooling, and growing application modularity through armbian-config. In addition to the technical achievements, the community has received international recognition for its leadership and innovation in open-source infrastructure: Armbian has been awarded the 2025 NetBox Hero Award by NetBox Labs, joining a prestigious list of projects that have demonstrated meaningful impact in automation and open infrastructure practices. What’s New in v25.5 This release brings dozens of contributions from across the Armbian community, targeting system performance, configuration management, and hardware enablement. Noteworthy improvements include: Extended board support: The release introduces or improves compatibility for several boards including the TI SK-AM69 (PR #7885), Banana Pi M2+ (PR #8127), BeagleBone AI-64 (PR #7918), BeaglePlay (PR #7917), and PocketBeagle2 (PR #7897). These additions reflect Armbian’s growing footprint across both legacy and cutting-edge single-board computers (SBCs). Upstream firmware integration: Rockchip devices like the Rock 5B and Youyeetoo R1 now enjoy better audio and HDMI support (PR #7925, PR #7934). U-Boot versions were bumped for key platforms to align with upstream. Kernel upgrades: Devices based on Rockchip64 now run on Linux kernel 6.14 (edge branch), bringing better performance and peripheral support. Additionally, kernel patching logic is now configurable (PR #8149), allowing developers to build plain mainline kernel. Filesystem and boot enhancements: Improvements to EFI partition alignment (PR #8053) and BTRFS subvolume support further refine system boot behavior and make image generation more flexible for custom installations. Stability and quality improvements: Updates include boot script fixes, enhanced serial console support, and a simplified logging framework, all designed to improve diagnostics and system reliability during early boot and provisioning phases. armbian-config: Simplifying Post-Install System Management One of the biggest areas of growth in Armbian v25.5 is the continued evolution of armbian-config—a system utility for configuring Armbian images after installation. Whether setting up a home automation server or managing Docker containers at the edge, armbian-config now offers an impressive set of tools in a modular and approachable interface. Application library: Users can now deploy popular self-hosted applications directly from armbian-config, including Home Assistant (PR #235), Stirling PDF (PR #295), Navidrome (PR #367), Grafana (PR #351), NetData (PR #289), and Immich (PR #575). These modules are installed in isolated environments, making them easy to deploy, manage, and remove. Network and system settings: A more robust Wi-Fi station detection system improves wireless setup reliability (PR #286). New schematics and better documentation provide helpful context during network interface configuration (PR #278, PR #280). Overlay and BSP switching: Logic for board-specific overlays is now dynamically loaded, ensuring options are shown only where supported (PR #285). The BSP switching tool has been patched to correctly detect the branch being used (PR #281), and header installation logic was refactored to reduce redundancy (PR #277). These improvements reinforce armbian-config as a trusted utility for both new users and experienced developers building production or custom systems. NetBox Hero Award: Community Excellence Recognized Armbian’s impact reaches beyond code. In this release cycle, the project was selected as one of the winners of the 2025 NetBox Hero Awards by NetBox Labs. This award celebrates the community’s dedication to infrastructure innovation, automation, and transparency. Armbian was recognized specifically for its “elegant and extensible use of NetBox in support of a broad set of infrastructure needs.” This acknowledgment affirms the project’s alignment with modern infrastructure tooling and its unique role at the intersection of embedded systems and open infrastructure platforms.

Testing on Nanopi R2S revealed that U-Boot there does not have setexpr built-in. I expect it will be the same on the 'Rock64' board you have? To make sure - as I do not have your hardware here - can you check if the following commands work on your U-Boot monitor commandline: setenv b setenv c setenv a "a/b" setexpr b sub "a/" "" a echo ${b} setexpr c 1 + 1 echo ${c} fdt Also, to give a workaround (hopefully), the output of the following on the U-Boot monitor commandline: echo ${fdtfile} echo ${fdt_addr_r} echo ${kernel_addr_r} echo ${ramdisk_addr_r} ver Thx, Groetjes,

I'm dealing with a very annoying problem. Every iso I seem to get for bookworm minimal have the same problem that everytime I try to run nano the screen goes black. How to fix this?

I have built and used it with the latest source and still HDMI audio and analog audio does not work. Is there any way to get HDMI audio to work other than using the vendor kernel?

More attempts: As suggested by DeepSeek (ChatGPT was less helpful), I also tried changing the bluetooth service script to ExecStart=/usr/libexec/bluetooth/bluetoothd --noplugin=a2dp --noplugin=avrcp --noplugin=player and then restarting systemd itself and the bluetooth service, but no luck. I tried adding monitor.bluez.properties = { bluez5.roles = [ ] } to /usr/share/pipewire/pipewire.conf and restarting wireplumber, but no luck. I tried menu advertise uuids 0x1200 0x1800 0x1801 0x180a in bluetoothctl, to disable advertising the audio profiles, but no luck. But when in bluetoothctl, it really shows the audio connection being made when the phone connects.

When I change the country and keyboard settings with armbian-config, the keyboard change from qwerty to azerty but after a reboot, the keyboard is qwerty again. The country code stay correct as set in the config.

I don't know your plans for how things are supposed to proceed. But if you plan to continue using my firmware build, I would suggest transferring it to the SPI flash, provided you are not wanted to use any other firmware in there. - This relieves you from having to pay attention to restoring my firmware build when changing an image. - You have two firmware versions available to you, between which you can switch with the SPI-MMC boot switch. - Even without the eMMC module, you can boot an OS from another connected storage device. - The U-Boot console is also available with an HDMI monitor and a USB keyboard and can be used for analysis in the event of startup problems. Of course, it is also used to select various boot options if autoboot is interrupted.

My NanoPC-T4 is still alive: For a quick test, I used my NVME with my latest OS, which usually powers a different SBC: Please do not let it bother you that the NanoPC-T4 uses an outdated kernel to run the OS. This is due to my negligence in building the current kernel without the necessary hacks needed for proper HDMI functionality. Some of the hacks have now been proper implemented in mainline, while others are still in flight. Until this process is completed, I have decided out of laziness to temporarily use an outdated kernel, as I do not miss any functionalities that a current kernel could provide me. My status LED is not blinking at boot at all. To debug boot problems, blinking LEDs are the worst possible option. Only proper console logs are of value. During OS runtime, it is configured as an HDD LED to indicate access to the microSD, as this is important information for when it is safe to remove it. I am still running my firmware from the microSD, again out of laziness to copy it to the eMMC. But any of nessesary support for the NanoPC-T4 is availabe and maybe some boring day or some spezial demand let me revisit to configure it properly. Until then, the bitrottining configuration is sufficient to serve more or less as an always-on terminal server for several USB serial adapters, which provide me with console access to my other SBCs if necessary.

What do you think....? still needs touch and cam.

I've spent a couple of days googling and "all the AI'ng" this and I just can't find anything that will get my Orange Pi 5 or Orange Pi 3 Zero Pin 3 or 5 to do anything at all.

What am I missing? Thanks!

Thank you so much. 🤗 Let's buy the board, then.

Hi! I'm new here too. I tested my webcam using webcammictest.io, and it worked fine, so the hardware seems okay. If you're encountering the "Inappropriate ioctl for device" error with v4l2-ctl, it might be due to driver compatibility issues or kernel differences. You could try using a different Armbian version, like Jammy, to see if that resolves the problem

Seems Ubuntu from Canonical uses a customized kernel where CPU usage precision is improved. But Debian and Armbian use previous CPU usage precision settings?

I could solve the instability problems and I am using the 2.5Gbit port now without having errors and with full speed! changing the swich Flow Control On for 2.5Gbit devices ethtool -K <LAN-device> sg off sudo ip link set dev <LAN device> mtu 9000 using the actual dtb file posted above cp rk3399-kobol-helios64.dtb /boot/dtb/rockchip/ update-initramfs -u nano /etc/default/cpufrequtils ENABLE=true MIN_SPEED=600000 MAX_SPEED=1800000 GOVERNOR=ondemand nano /etc/rc.local for cpufreqpolicy in 0 4 ; do echo 1 > policy${cpufreqpolicy}/ondemand/io_is_busy echo 25 > policy${cpufreqpolicy}/ondemand/up_threshold echo 10 > policy${cpufreqpolicy}/ondemand/sampling_down_factor echo $(cat policy${cpufreqpolicy}/cpuinfo_transition_latency) > policy${cpufreqpolicy}/ondemand/sampling_rate done for i in $(awk -F":" "/ahci/ {print \$1}" < /proc/interrupts | sed 's/\ //g'); do echo 10 > /proc/irq/$i/smp_affinity done for i in $(awk -F":" "/xhci/ {print \$1}" < /proc/interrupts | sed 's/\ //g'); do echo 20 > /proc/irq/$i/smp_affinity done exit 0 nano /usr/local/bin/make_nas_processes_faster.sh #!/bin/sh -e for i in `pgrep "iperf3|smb"` ; do ionice -c1 -p $i ; taskset -c -p 4 $i; done # >/dev/null 2>&1 running as a service

Is there a way to copy the system from sda1 [M2-Sata SSD (2280)] to emmc (uboot) from the running system without losing the configuration? If it's possible, how can I do this including configuring the changes? What is the maximum size for the M2-Sata SSD (2280)? https://wiki.kobol.io/helios64/m2/

Hello, With kernel 6.6.56-current-rockchip64 the audio works correctly: cat /proc/asound/cards 0 [RK809 ]: simple-card - Analog RK809 Analog RK809 1 [HDMI ]: simple-card - HDMI HDMI With kernel 6.12.30-current-rockchip64 the RK809 card is not available: cat /proc/asound/cards 0 [HDMI ]: simple-card - HDMI HDMI How can this be solved ? Thank you so much !

openssh-server should be installed by default on all images/configurations.

thanks again, I'll do this soon.

chatgpt advised to type ":UTC" or ":Europe/Berlin" and it helped.

Same answer as above. Without serial logs impossible to debug. It leaves to mention that this board is not officially supported but configuration has been provided by a community effort. Board status is unknown to the core Armbian team.

No. Yes. This is the most stable and well-developed kernel.

kernel_ramfs is located at /dev/block/mmcblk2p6 Have extracted with dd and copying through wifi adb. Interesting usb debugging is enabled in tvbox, but when connecting usb v3 cable to tvbox, host machine does not see the 'adb device', adb connection over wifi is ok. Has anybody used USB adb on this device?

No, that won’t work. This is a Armbian Linux forum. If you need android support try xda forums.
