I compiled Linux from hardkernel–it works with the devicetree from petitboot firmware. There's a emmc-data-4b node (not in their source code) which does: &emmc_conf_pull_up { mux { drive-strength = <3>; groups = "emmc_nand_d0", "emmc_nand_d1", "emmc_nand_d2", "emmc_nand_d3"; function = "emmc"; input-enable; bias-pull-up; }; }; Trying this with mainline e.g. overlay=g12b-odroid-n2-spi isn't enough here. No option to wakeup (ir, lan, keyboard) is another reason to stick with 4.9.

Subject: Bluetooth: Unknown BR/EDR signaling command 0x16 / Wrong link type (-22) on meson-gx / Banana Pi M2 Pro Description: When connecting modern Android (POCO F7) and Windows/Linux devices (Lenovo Legion) via Bluetooth to Banana Pi M2 Pro, the dmesg log gets flooded with BR/EDR signaling errors during connection/disconnection phases. Steps taken: - Forced 'ControllerMode = bredr' in /etc/bluetooth/main.conf - Disabled USB autosuspend for the BT controller (set to -1) Logs: [ 345.122975] Bluetooth: Unknown BR/EDR signaling command 0x16 [ 345.123005] Bluetooth: Wrong link type (-22) Environment: - Board: Banana Pi M2 Pro (Amlogic S905X3) - Kernel version: 6.18.34-current-meson64 nano armbianEnv.txt extraargs=usbcore.autosuspend=-1 The problem with Bluetooth on bananapim2pro is that I constantly have trouble connecting. My tweaks to the settings fixed it somewhat, but not 100%... Finally, if all else fails, I use this method: sudo rmmod btusb sudo modprobe btusb sudo systemctl restart bluetooth sudo systemctl restart bluealsa But I have a question: are there any kernel/driver fixes or updates for this Bluetooth model?

Hello guys, i got 2 old fullbox rikomagic mk802 stick android mini pc. Variant Allwinner A10,Ram 512Mb. I tested armbian 26.05 via 4 config : limea1000 boot ok pcduino1 ok cubieboard ok olimex a10 lime stuck at boot os stage, same with official debian 3.4 kernel images of olimex enabled video output for desktop environment. It boot but will take a lot of time to finish

Hello, I believe @m1zfs's work on the DKMS modules is available here: https://github.com/vitalijborissow/rk3568-npu-ODROID-M1 I have spent many hours trying to get the NPU working on my ODROID-M1 (8 GB) running Armbian 26.5.1 with current kernel 6.18.x as well as edge kernels 6.19 and 7.1. I also tried building the latest Armbian image from source (July 19 build including U-Boot 2026.07), but so far I have not been able to get the device tree / overlay and DKMS modules from the repository working on any of these combinations. The system always fails to boot. Fortunately, I can capture the boot process through the serial console and see where it fails. The log shows a kernel exception related to enabling the RK3568 NPU power domain: rockchip-pm-domain fdd90000.power-management:power-controller: failed to get ack on domain 'npu', val=0x1ee platform fde40000.npu: Adding to iommu group 3 Internal error: synchronous external abort ... Workqueue: pm genpd_power_off_work_fn ... rockchip_pd_power From the log it appears that the crash occurs before rknpu.ko is loaded. This makes me believe the issue is more likely related to the device tree, overlay, power-domain, regulator, or clock configuration rather than to the DKMS module itself. Has anyone seen a similar issue on recent Armbian kernels, or can suggest a direction for further troubleshooting? I am still willing to spend some time investigating this and would appreciate any ideas or hints.

OK great that you got it working now! 2GB RAM works fine for HA, at least when running Supervised. I am not sure if Armbian can improve more when Supervised, as this is not supported anymore from the providers/developers of Home Assistant. I think a reason people go from SBC to Intel NUC is because there are things like VMware that IT pros might know from their profession/company. And RPL very long by default had/advised to use 32-bit also on more capable devices like RPi4 with 2GB RAM or even more. And also running from SD-card, and those wear out under high load and many writes. The whole problem with 'traditional RPi' is that it is unusual 32-bit ARMv6 build and not the standard 32-bit ARMv7 which is the minimum for support from Debian and most other distros. And in addition, 32-bit builds do not support the standard Linux Kernel Virtual Machine HW, standard in all 64-bit capable CPU's. Intel/AMD CPU's have support for HW virtualization also for 32-bit and much more known and commercial (also closed-source) hypervisors like VMware are pushed a lot more then the standard Linux build-in QEMU/libvirtd/KVM. So with 64-bit Linux, especially also on ARM, you get it by 'apt install virt-manager' and then you can run other OSses/images at full HW speed and is separated from the host OS, e.g. Armbian. Because images, many files or bigger databases are a burden for simple SD-card. Also because multiple OSses at the same time, it easily needs more RAM than the usual 1GB on SBC's like RPI3. Via virt-manager GUI and also CLI tool virsh, you can then run the generic UEFI bootable HAOS. For long-term and decent 24/7 operation, you will need SSD for storage. RPi's don't have that, you need adapters and HATs etc. But many other SBC's do have, so if you have an unused NVME for example, it fits perfectly in RK388 boards like ROCK5B for example. It is 4-lane PCI-E v3, so similar speed as Intel miniPC's. And most important, lower power consumption for similar total system price, at least before the RAM+storage prices went sky high. I measured my NanoPi-R6C with Samsung 970 NVME and Armbian Trixie (6.1.115 kernel) and is about 1.5 Watt when idle or doing some light tasks like running simple initial HAOS as Virtual Machine.
