Hello @Aknot, better late than never? This is likely because USB OTG support is on out of the box now. You used to have to add an overlay to get it to work. You will need to modify the the overylays to change this.

I found my NanoPi Neo Air's could not list or connect to some wifi networks. Some investigating found this was because channel 12/13 are disabled by default. Nothing in runtime had any effect on the output of iw reg get as it should have. Patching in some firmware fixes worked for me. wget http://ftp.be.debian.org/pub/software/network/wireless-regdb/wireless-regdb-2025.02.20.tar.xz tar xf wireless-regdb-2025.02.20.tar.xz sudo cp wireless-regdb-2025.02.20/regulatory.db /lib/firmware/ sudo cp wireless-regdb-2025.02.20/regulatory.db.p7s /lib/firmware/ sudo iw reg set AU #Australia I can now connect to wifi channel 13. Now for my question: I read in this old thread that armbian-firmware-full is required for wifi. would that mean that the full firmware package is desirable for the Nanopi Neo Air? When running apt-get install armbian-firmware-full it states it will consume an additional 1gb of disk space. Hardly desirable for a little device. VERSION v25.5.1 for NanoPi Air running Armbian Linux 6.12.30-current-sunxi

I disassembled my tv box - there are 4 screws under the 4 rubbery feet. Removed the motherboard and I drilled some holes of 1/4 inch (7 mm) diameter through the bottom plastic piece. Then I placed a USB fan underneath the tv box and wow the temperature really goes down and stays down around 45 C to 60 C depending on work load. The fans are 80mm and 120mm in size. I chose 120mm to be sure.

That's a very good idea, especially if my online accounts that have my photos would ever become problematic for any reason. I have armbian on a tv box with SMB (samba) and with a USB 3.0 hard drive. The tv box is connected by gigabit ethernet to my home network. So I am going to try these apps - PhotoSync, FolderSync, CX File Explorer - on my android phone to backup my personal photos and videos and determine which is easiest and fastest. Which app on your phone/tablet have you chosen to use to backup your photos/videos?

you can install "ethtool" and run ethtool eth0 on the command line. look for the line that shows " Speed: " how did you install ZFS in Armbian?

Hello everyone. @salas I have just implemented the out-of-box (OOB) network driver functionality in a new commit to the repository. This should serve as a temporary patch for now (or potentially a permanent one, depending on if/when the driver gets mainlined into the Linux kernel). @whywontitwork Thank you very much for the feedback and for testing the image. I need a bit more information to help track down the issue. My suspicion is that the system is successfully loading u-boot but failing to load the kernel. However, without debug logs, it's difficult to know the real cause. To help diagnose this, could you please tell me how you flashed the image? I flash my builds to a microSD card using the Balena Etcher software. Are you using the same method or a different one? I appreciate your support in getting the Orange Pi 5 Pro maintained! One of my main motivations for starting this project was to get Panthor support for the Mali GPU too. I can confirm that on my end, with the image I've built, the latest version of the drivers works correctly. Getting Vulkan and OpenGL running on an RK3588 board!

The display does not work at all, just the backlight turns on and nothing shows up on the screen. I think looking at what you suggested I should try to take the good parts of these dts files and see what I can get working. After that I will try to compile uboot with that mixed dts file. I will take some time out to make this mixed dts file. I did try running pi-hole on this and it worked for some time, but it needs further testing. Will try the above and report back. Thanks, Shivam

Lightdm wasn't seen as being installed but I installed it just to see what happened but no change. sudo nano /home/*/.xsession-errors gave the following information.

I'm not sure what connection Efe Çetin has as it's an Orange Pi 5 board, so perhaps they have some form of official input to design. I'd love to know what triggered the change. And yes, like many things, no guarantees but if what happens can give pointers to preventing it happening to others in the future or recording potential solutions for those that might end up in the same position.

Things you should try: Capture the dmesg since before the sound file is playing Try again with the sound file in the main EXT4 partition

I have long struggled with a problem with my Rock S0: If using the USB OTG port in device mode, the connection would suddenly drop randomly, minutes or sometimes hours after initialization. I spent months on and off looking for solutions, and I finally found one, so here it is if you ever find yourself having the same problem. Basically, it is caused by the SoC being very sensitive to voltage drops before the USB controller interprets it as the connection being lost. It's far more sensitive than it needs to be, given that my device is bus-powered and so the OS never actually needs to worry about a connection loss. If the connection is lost it is because I have unplugged the cable and so the device would be shut off regardless. Anyway, the solution lies deep within the RK3308's control registers, where I found the following: Three bits named "B_validsession reference tuning". There's no other explanation on what these bits does in the manual, but it sounded vaguely promising since I had been able to establish that "b-session valid" is actually the name of the status/interrupt that the vbus voltage affects in OTG device mode. Other registers related to the b-session valid status didn't work, however, including filter times, interrupt masks, force high bits, etc. But luckily this one register finally did the trick. The default value of these three bits are 000. Without any documentation I basically just had to guess what to do, so I tried setting them to 111 instead. And that seemed to work. It significantly lowered the voltage on the vbus pin required to trigger a disconnect signal. My connection was finally stable. Here's how you can do it yourself. First install memtool via apt, then run: memtool mw 0xFF008018 0x1C001C00

I have a pihole on one of my devices that I backup using shrink-backup. When pihole released 6.0 there was a bug that rendered my system unstable so I found it easier to revert back to 5.x until they fixed the bug. The restore worked without any issues whatsoever. The pihole database is only a db file and the records between the backup and to date is obv lost, but as for integrity of the system it's only a query log so it has no impact on pihole itself. As a matter of fact, you can run pihole without any db history at all. And IIRC the database history is 90 days by default, not one year. A btrfs send|recieve is only a file backup, it will never handle boot process or anything like that. You will also need to do it on every subvolume individually since send|recieve only takes one subvol, not even nested volumes. You will also have to make the source subvolume read only before issuing the send, but I guess that is what you mean by saying "make atomic snapshots". It's also very slow compared to rsync. Besides, using btrfs send|recieve does not solve the issue that copying a database that is in use might corrupt it, shutting down the application using the database before making a backup is. As a matter of fact, it might just make things even more complicated since you have to make the database (subvolume) read only during the send so the application might freak out from not being able to write to the database (unless you snapshot it first like you mention, but then you still have the same problem that an open database might break after being backed up). btrbk solves this (I think) by creating a snapshot (snapshots become read only by default) from the subvolume first and then send that, but you can't btrfs send|recieve a read/write subvolume, but again, does not solve the issue that the database is open. https://btrfs.readthedocs.io/en/latest/btrfs-send.html Fun fact: shrink-backup can backup btrfs devices. https://github.com/UnconnectedBedna/shrink-backup?tab=readme-ov-file#btrfs

Well its equivalent so other than vendor not beeing in a database does not count as custom in my books, but that is beside the point. Armbian correctly recognizes the size and I can write to it and that is important. Now flashing an existing image is simple. My preferred way is dd as described by Piter75: dd if=uboot.img of=/dev/mtdblock0 bs=4K for u-boot images and dd if=idbloader.img of=/dev/mtdblock0 seek=64 bs=512 conv=sync dd if=u-boot.itb of=/dev/mtdblock0 seek=16384 bs=512 conv=sync if used with image tree blob. Nice thing is that if new u-boot hangs or does not boot I can just short pin 23-25 to boot from SD card and try again. Since I have an 8Mb flash I would really like to bake in m.2 to SATA drivers - for ASM1166 in my case. Any pointers are welcome. DeMo

Two days ago I upgraded the kernel to 25.5.1 (6.12.30-current-sunxi) from 25.2.3 (6.12.20-current-sunxi). Since then I have no longer been able to play a certain title (FLAC file) in mocp. In case it's relevant, the title is: "Malukah - Awake (The Dragonborn Comes)". Symptoms: dmesg starts showing kernel trace output at 1:43 of the song mocp finally stalls at 1:52 and it's impossible to interact with it from that point on Is there anyone here who would be able to provide pointers on how to debug this? I am a developer and I have done some work with Yocto/OE before and wouldn't be afraid to get at this with a debugger. Since it's nicely reproducible, I could switch between those package versions to investigate. From the trace output it looks as if this is in exfat code. Makes sense, since the song is getting played from a USB key that is exfat-formatted. Here's the dmesg output with the two traces towards the end. I decided to include a few messages up to the point where systemd starts: [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 6.12.30-current-sunxi (build@armbian) (arm-linux-gnueabihf-gcc (Ubuntu 13.2.0-23ubuntu4) 13.2.0, GNU ld (GNU Binutils for Ubuntu) 2.42) #1 SMP Thu May 22 12:29:54 UTC 2025 [ 0.000000] CPU: ARMv7 Processor [410fc074] revision 4 (ARMv7), cr=50c5387d [ 0.000000] CPU: div instructions available: patching division code [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] OF: fdt: Machine model: Cubietech Cubietruck [ 0.000000] Memory policy: Data cache writealloc [ 0.000000] Reserved memory: created CMA memory pool at 0x4a000000, size 96 MiB [ 0.000000] OF: reserved mem: initialized node default-pool, compatible id shared-dma-pool [ 0.000000] OF: reserved mem: 0x4a000000..0x4fffffff (98304 KiB) map reusable default-pool [ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x0000000040000000-0x000000006fffffff] [ 0.000000] HighMem [mem 0x0000000070000000-0x00000000bfcfffff] [ 0.000000] Movable zone start for each node [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x0000000040000000-0x00000000bfcfffff] [ 0.000000] Initmem setup node 0 [mem 0x0000000040000000-0x00000000bfcfffff] [ 0.000000] On node 0, zone HighMem: 768 pages in unavailable ranges [ 0.000000] psci: probing for conduit method from DT.

Yes, your logs show hundreds of errors, so it will be hard to pinpoint which one it is exactly. Here's a few things I can suggest that might move you along. "sudo service restart lightdm" # see if X now comes up on your TV, assuming that lightm is what you are using "sudo nano /home/*/.xsession-errors" # check the errors listed in those log files, they are more specific Can you try to flash an (older) image to a microSD card, boot off it and see what the results are? @Efe Çetin is the maintainer of your board, maybe he has a comment? Your board is in community-maintained status for armbian. There are no guarantees.

Do you know how to compile your own images? Do you know how to use "git bisect"?

@WERNER If I try to use xrandr through an SSH connection using putty I get the response 'Can't open display' I can use it in terminal via remote connection and the basic command returns: Screen 0: minimum 256 x 256, current 1364 x 768, maximum 16384 x 16384 rdp0 connected primary 1364x768+0+0 0mm x 0mm 1364x768 50.00* Messing around with xrandr, there seems to be more than one way to skin a cat, if I try something like: xrandr --output rdp0 --mode 1280x720 I get a response of 'cannot find mode 1280x720' I experimented with all manner of normal resolutions that I have used before and even tried both the minimum stated by the plain xrandr command, 256x256 and 16384x16384 but get exactly the same response. It would seem likely that 1364 x 768 is why my TV is not showing the desktop because I suspect the resolution is not supported. But I feel between a rock and a hard place for something that seems become hard locked. @laibsch I poured through the log I posted above but much of it seem to be more rocket science, so hard to pick out something that logically points me in the right direction.

The last working image is 25.5.0-trunk.256, which is still available for download. I will try to look into the situation as my time allows. Thanks for the hint where to start.

I am always happy to see people keeping old hardware running. But I think it would be best to make the necessary changes in Armbian itself. I am happy to help out where I can be useful.

The ones I linked. You mentioned that you have no experience to compile stuff. One option is to target another SBC or a virtual machine so that you can focus on learning the build framework (explicit instructions are already given in some of the links) instead of having to deal with a multitude of issues (setting up your compilation host, getting compilation to succeed, finding the artifact to flash, only to then run into the next issue that armbian currently does not support your board). With a virtual system, you can be sure that you should get a working image. You can then focus on the compilation and familiarize yourself with that before jumping into real hardware enablement.

Do you have specific instructions for installing the X96 X6? @Chris4arm Thank you very much.

I added a suggestion at the PR how to implement the driver while building to allow network oob.

I suggest you check the logs for clues what is going wrong. syslog, .Xsession-errors, etc.

Thank you for reporting about this issue. What is the latest image that still works? Is it still available for you to download? Maybe this is the change you want to revert and see if that brings things back in line? But supposedly, that commit was boot-tested by Niklas. Your board does not have an official maintainer in armbian, so I suggest you contact Niklas to find out what the situation is for him.

Ok I was able to get the LCD working with a self built image, by copying the linux config from the armbian.com image to the build/userpatches/linux-sunxi64-edge.config Currently rebuilding without the successful linux config, and then I will look at the difference Update: I didn't find any differences and the new image without the userpatches config accepts the LCD DTS and bin file. Ok, I dont understand what was happening before. Now I am getting the same X11 error as before: MESA-LOADER: failed to open panel-mipi-dbi: /usr/lib/dri/panel-mipi-dbi_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/aarch64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) I see that this panel-mipi-dbi_dri.so is part of libgl1-mesa-dri debian package, in DEBIAN SID, but not Bookworm https://packages.debian.org/sid/arm64/libgl1-mesa-dri/filelist https://packages.debian.org/bookworm/arm64/libgl1-mesa-dri/filelist Next, when I rebuilt the armbian OS with xfce desktop, I get the same panel-mipi-dbi-spi error: can't find the bin file. I checked the config again... and it was the same Update: It was easier to build Sid minimal, and install labwc (wayland), just remember to install seatd: https://eirenicon.org/labwc-a-tutorial/
