Hi there, 2 days ago I did apt update + apt upgrade on my OPi3, everything fine. Yesterday I did a system reboot (as suggested "kernel changed"), then Eth port went dead. No even ARP works (ARPING). Have tried: - ifconfig shows correct values, - ethtool shows 1Gbps FDX connection, also same on router (OpenWRT TL-WR1043ND w 18.06 software), - changed eth cable, - on other OPi connected to same switch / router (also went dead) depowering device helped, but not on OPi3, - ARP shows MAC/IP not resolved, - WiFi (configured as AP) looks working. - also changed port on router and did power cycle device, nothing helps. - on r…

Hi, I'm running fine my Orange Pi PC+ with an external HDD since many years and decided to switch to an 1Tb SSD recently. SSD enclosure has it's own power supply. After few hours/days my OPi is not responding using SSH, and ethernet adapter is like frozen. Unpluging the ethernet cable generaly resolve the problem. What could it be related to ?

Hy I'm currently running the latest experimental image on my NanoPi Neo Core 2. Works great haven't had any problems with it. Now my question when does the "experimental image" state change to a "stable build"? What are the criteria? Andy

TKaiser. If you install the Desktop version of Armbian 5.10 then the following list of codecs (containing h.265 with 8 bit but not 10 bit!) is available for HW accelerated decoding: http://linux-sunxi.o...ed_codec_matrix Is 8 Bit versus 10 Bit a limitation. Can the Orange Pi PC with Armbian 1.10 decode all HEVC 8 or 10 bit encoding to 8 bit decoding, or can it ONLY do 8bit encoded to 8 bit decoding? Seasalt

Hello, I am having strange problem with Olimexino A20 Micro, Ambian 5.38, 4.14.14. After every 2-3 days standby with minor cpu usage I am getting an FS error.

I have tried to use the nand-sata-install to allow me to boot the roots from an external USB HDD. It goes through the process but after rebooting, the "loading kernel" message appears and then nothing - I have tried this a few times and even used the latest version of the script on GitHub. Any ideas on how to make this work - I have a external USB HDD (500mB).

Hello community Here are the versions I’m using: Kernel: 5.15.48-sunxi OS: Linux nanopineo 5.15.48-sunxi #22.05.3 SMP Wed Feb 19 15:56:03 UTC 2025 armv7l GNU/Linux I’m having a problem. Sometimes, during boot, I see the following log: After this message, the system halts.

I noticed that the device doesn’t use the overlay_prefix variable from /boot/armbianEnv.txt. It shows this message: I tried adding the overlay_prefix variable manually in the boot.cmd file, but it didn’t help. …

Hello, in the company where I work, a nanopi M1 plus was purchased and we are developing a firmware to run on the device. In our code we need to change the settings of the active wired connection at that time, but we can not do it due to an error.

Error: failed to modify connection 'Ifupdown (eth0)': Connection is read-only The command is executed correctly if the connection is not managed by NetworkManager, so when in the file: "NetworkManager.conf" the "managed" parameter is set to false.

My Opi3 has been running armbian for over 2 years (edge kernels & usually fully up-to-date). I have been using eMMC & I noticed an apparent slowdown about 6 months ago. As it performs cron-based tasks and is a stats collector, this performance was not noticable but doing a manual BIG dist-upgrade, it seems to take forever (20 minutes to do what should be under 5 minutes). If I run "mmc extcsd read /dev/mmcblk1", the results tell me that the eMMC is at least 90% used whatever that really means. Is this a sign of imminent failure ? hdparm shows read results of 17 MB/s which is actually slower than my alternative SD card boot device and nearly 1/10th …

Hello again, since I use the NAND-Flash to boot and I want to use the new kernel, which doesnt support NAND yet, I'm curious if its possible to use both: 1. Can I boot the new kernel from NAND? Since the new kernel is started after uboot, it should be possible? 2. Afterwards I have no possibility to update the kernel again. Or do I have? (Without SD-Card) a.) the nand-tools requires the nand-driver??? Or is there a possibility to writea prebuild image to nand without kernel-nand-support? b.) is it possible to start an old kernel from the new for upgrading? Tried "kexec uImage", but it doesnt work. Maybe I need the zImage instead of uImage? best regards

One of the Bananapi-m1+ GPIO pins is connected to an LED that I need to illuminate as quickly as possible after power-on. Using an older Fedora Linux release, it turns on in 3 seconds. Using a recent Armbian build, it takes 45 seconds. I've tried many ways using services with early "After=" targets, to access /sys/class/gpio/* interfaces more quickly, and this improved it by 5 seconds, but it's still too long. So I tried adding a device tree overlay to set the default value in the pin controller. I am confident the DT overlay is getting read and parsed properly, based on seeing artifacts in debugging streams, but still, no LED illumination. Anybody got any ideas on …

I'am running the latest Stretch server version on a PiOne (Linux 4.14.65-sunxi). I think that something is going wrong with the logrotate. The rotation is done in /var/log.hdd directory (see also the scripts in /etc/logrotate.d/). But the original file of each is in /var/log directory and is not "cleared" after the rename, because it is not renamed. So, if Zram copies /var/log directory to the /var/log.hdd directory, the original file in /var/log with old logging and included new logging is written to the /var/log.hdd directory. In the next logrotate this growing file is compressed. In this situation/in my case the compressed files contains all the loggings and no…

Hi, Seen some posts where mentioning that depending of the version of kernel there is either FEX or DTS usage, old ones called Legacy, using FEX to define GPIOs and Peripherals pins. Wit Mainline Kernel, is using DTS.

I'm trying to figure out why Firefox-esr crashes form time to time on my Olinuxino-Lime A20. I also have a Banana PI (also A20) and on that board Firefox never crashes. On both boards I use the legacy kernel, and I use uBlock adblocker on both boards. The Olinuxino has 512 MB RAM and the Banana Pi 1 GB.

Do youi have any suggestions on where to find crashreports? Thanks in advance and much appreciation for your continuous work on the Armbian distribution!

After doing a 'firmware upgrade' from armbian-config, it identifies itself as a Banana-pi. Is it normal? The MOTD is BPi and armbian-config shows BananaPi as well.

Hi, I own the first Orange Pi (A20, VGA, HDMI, NAND, 4xUSB, WiFi). I notice there is no Armbian image for download anymore. The last one I still have is a 3.4.113, 5.25 Ubuntu/Xenial-default-desktop (currently running from the NAND very well, but I can't seem to run the wifi in AP mode). Is Armbian for this board is dropped for good ? Is there a way to update my 5.25 to last version without breaking everything ? Or maybe convert a A20 image to this board, using the working image I'm currently using ? Thanks !

Attention, whatever you do next is at your own risk! Fixed dts overlay file for Armbian 23.02.2 (attached). 1.

As a bonus, I added an indication of reading from a flash card as a red LED (this can be turned off). 3. I also activated the host on the micro-usb connector - now you can connect something else via the otg adapter as a third USB connector. To apply t…

Hi, I wanna try the armbian for banana pi M2 but when i flash the image in the microSd card with Rufus (i'm on windows 10) the pi does not boot correctly, i.e restarting every 10 seconds. Afterwards the card is not easy to reformat, not accessible on windows. In Rufus I do (i tried with 2 different cards): - choose the .raw file - then the combobox is set to DD image - finally i click on start So is there something I totally miss? Thx

Hello! It's about installing Armbian on OPi+ 2E without a reliable sdcard and with no proper card reader - U-Boot goes to sdcard, Armbian image goes to USB dong then installed to eMMC. I did this once but can't remember what device was the sdcard in Android, if anybody knows it would be great to share. It mounts as /dev/block/vold/179:1, but writing (dd) u-boot.bin to 179:0 or 179 doesn't result in a bootable sdcard (the OPi boots from eMMC, and as far as I remember if it has bootable sdcard inserted it should boot from it no matter what is on the eMMC). There was also an issue with the nand-sata-install - I had to remove some lines as it wouldn't allow writing …

I have a problem with annoying randomly flickering cursor in armbian 5.34.171102 ubuntu desktop with mainline kernel. It's plain system after instalation, just chromium browser opened. The legacy kernel is OK on my board Orange pi plus 2e. Any idea what might cause this<

With an earlier version of Armbian (Server) I was able to use my Orange Pi Pc + to feed data back to Flightaware, Flight Radar, Planefinder, ADSB Exchange. An upgrade put an end to that in the latest version. Is it possible to get this working in future Upgrades of Armbian? Piaware Install

Hi, I have ten orange-pi pc plus with Ubuntu 20.04.2 LTS with Linux 5.10.43-sunxi burned onto emmc, and twenty orange-pi pc plus with Focal 21.05.6 with Linux 5.10.43-sunxi burned onto emmc. In an attempt to provoke the same issues we have with Xenial on these boxes, I have all of them rebooting (shutdown -r now) once every 10 minutes. They have all been under test for several days. They are all connected to a LAN backbone, but the LAN is not connected to the internet, so whilst they may be attempting to do unattended upgrades, for example, they are all failing. This is a deliberate part of the test. Of the twenty Focal 21 boxes none have failed. …

Is this the right place to post this type of content? I have a board for Orange Pi. Since I'm usually using windows, it's very inconvenient to burn u-boot. I'll post it to github later if you guys are interested! （Machine translated, English not so good, don't know if the description is apt or not.）

Hello, As The title, I think there a way to replace the vanilla kernel from the legacy kernel? And it is running the legacy kernel anyway cubietruck, but the mood is what can be switched to vanilla.

Hi everybody, I need your help in setting the default values of some or all GPIO Pin, so that it will be always activated after reboot instead of deactivated like the default is today. The reason for this is that I've connected a relaisboard to some GPIO Pins that will need "1" to be deactivated . Everything works fine, I can control and work with these Pins like needed by using "1" for OFF and "0" for ON. After booting up my BPI I initialize the needed GPIO Pins via export the pins. That will create virtual directories for these Pins with these defaults: direction -> in value -> 0 Like I mentioned, my relaiseboard need a logica…

Hello i use armbian on my orange pi and have a problem about the wifi connection. I have my orange pi near my 3D printer. When i plug it in, to boot the armbian it works great. But the orange pi will (SOMETIMES) not connect to my wlan. When i change the room and put it nearly my pc, it will connect without any problems... So i check the wifi quality: - near my pc i have a link quality 70/70 - near my 3d printer i have a link quality 64/70 and signal level: 46dBm is this to low for a easy connection?? thank you

I have OrangePi Zero and have forgotten password. I have two users, root and ordinary user. Is it possible to change some file on SD card to reset password? Regards, M.

Hi, I have a Opi+2 board which has an Armbian system installed in its emmc. Now I want to format its Emmc and reinstall Armbian but the problem is I don't have a proper SD card. So I need to do it without an SD card. I have a running system on it, so I can reach the working system. Is there a way of formating it while its running? For example a command does the same thing with "dd if=armbian.img of="/dev/mmcblk1"" (which won't work while there is a system working, its just an example) (mmcblk1 = working system, emmc)

Hello, My name is GNUser and as the name implies, I use GNU system For privacy and security reasons (though also some philosophical ones) I decided to run only free software on my machines. For example my laptop has Trisquel installed which is a FSF approved distro. I also use Debian a lot, with the main repository only available (other repositories might contain or suggest non-free software). My question is this: the images of armbian available here, I understand they are built on top of debian, but which kernel are they using? The kernel that Debian usually provides (for x86/64) is a debblobed kernel, with no proprietary pieces. Is that the case with these ima…

Hello armbian forum, I have an Orange PI Win plus with armbian desktop legacy kernel 3.10.y on it. I also have a extension board from my Raspberry 1 which I want to use. The Problem is that the extension board needs the pins 8 & 10 for UART communication. I read already that UART(2) over pin 8 & 10 is used for Bluetooth? I don't need Bluetooth and want to disable it to free up the pins. Uart1 Pin 38 & 40 and Uart3 Pin 11 & 13 are working finde. How can I make this? With overlays or editing the .dts files?

The freedombox.org is libre software. The software provides a server solution having a list of preinstalled programs. This post is about if the orange pi one can get a libre software version of the freedombox installed on it. The orangepi one is interesting because of its price and performance. What determines if you can install a libre software image on an arm computer? Is it uboot support? Can you install a libre software version of the freedombox on an orange pi one? The freedombox people say, if you can install pure debian on an arm computer, you can install the freedombox too. Can I ask…

Hi all, recently my Banana Pi Pro running Armbian 26.5.1 with Debian Trixie received a kernel update from 6.16.8 (which it has been running on for quite a while without issues) to 7.0.12. Since then, it randomly freezes shortly after booting, sometimes I also can see a kernel panic (see attached pictures). Has anyone else run into this issue? What can I do to fix this? The old kernel no longer appears to be present in /boot, which makes it difficult to return to another kernel (trying to run something like apt-get typically quickly results in the aforementioned freeze).

Hi. I'm a new user. I have a Banana PI M1+, that is connected to a monitor with maximum resolution of 1280x1024 and with only DVI port. I'm using Armbian_4.5_Bananapi_Debian_jessie_3.4.109, and I installed XFCE using tasksel. If I leave it without any user interaction, the monitor goes to sleep, and I'm not able to wake it up anymore. But it works, because I'm able to connect to it using putty from another computer. So I tried to install Armbian_4.5_Bananapi_Debian_jessie_3.4.109, but I have the same problem. I tried also to disable "Switch Off After" in the Display section of power management without success. Can someone help me please?

[This is a repost of my own post at orangepi.org.] Hi, I'm very excited to use the Armbian on Orange Pi One. Without rebuilding a kernel or fex file, here is how to configure the Orange Pi One governor so the "[ 150.135554] [cpu_freq] ERR:set cpu frequency to 648MHz failed!" and "[ARISC ERROR] messages no longer appear in dmesg. We will set it to 912MHz on the low end and 1200MHz on the higher end which scale up and down properly on the Orange Pi One. This is until you update your fex file and/or kernel config to use different values for the CPU frequency scaling that are a little different on the Orange Pi One than they are on the Orange Pi PC. Put it in your /e…

I've got an Orange Pi PC2, and I'm running some pretty CPU intensive tasks on it. However, I'm running into a situation where the processor is overheating and shutting down. I've got a bunch of OPiZero's, and on those I'm used to the kernel automatically throttling the CPU frequency down and/or shutting off cores in response to rising CPU temps -- but I'm not seeing that happen on the PC2 -- it just stays at max CPU speed until it overheats and shuts down. Is there a way to enable that same behavior on the PC2? (I'd rather it throttle down the CPU frequency instead of overheat...)

This started happening since accepting the kernel when I used apt to upgrade the BananaPi Pro sbc I've got. armbianmonitor report: https://paste.armbian.com/izuboducul @teknoid are you aware of this?

I test in Orange pi lite libMali.so, both X11 and framebuffer. Xenial' X11 mode tests by glxgears fps is around 250-270 but Jessie is around 400-420, billiard game that use Opengl is noticable different. For framebuffer, I use retroarch that also noticable slow in Xenial. Anyone know why Xenial libMali is slower than Jessie?

So I apologise in advance because I'm sure it's probably on this forum but I could not work out the buzzwords to find it. For whatever reason, I upgraded the cubietruck with armbian which has been on since forever and rebooted for the first time this year. On reboot it failed to find /boot and a few other things and kept bootlooping, resetting itself and then following the same procedure. I already had installed the system to my SATA SSD, so this isn't a huge deal. I've flashed the latest armbian release onto the SD card and it boots fine. Now, I see there is an install to sata option in armbian-config but it gives me the warning that it will wipe …

I've installed Armbian 23.11.1 Bookworm on a FriendlyElec ZeroPi. On the cmdline the linux command who gives the following output: dgs pts/1 1011643795265722162 (172.20.10.14) Usually it should be (as on a Debian Bookworm distribution): dgs pts/0 2023-12-14 10:43 (172.20.10.14) Instead of showing date and time the Armbian who command outputs this long integer number. Why? Is this a bug or do I miss any configuration? PS: the locale settings is identical on both devices, date shows on both devices the correct time.

I've installed Armbian 23.11.1 Bookworm on a FriendlyElec ZeroPi. This version works flawlessly. A few days ago I updated to Armbian 24.2.1 and since then the ZeroPi crashes and hangs.

Hi all, I've been trying to install ft6x drivers on a nanopi neo air, which has armbian with legacy kernel, but it seems there is no support for ft6x capacitive touch panels. There is a code from Focaltech here, which is ft6x06 driver code. I added the code to kernel and compiled it, but the problem is: what should I do with fex file? Or is it right to do this? (I was not surprised that it didn't work). Can I change the current ft5x code to make ft6x works? There is also a support for ft6x family on mainline kernel. Is there any hope to adopt that code? Thanks.

Hello there! Its nice to meet everyone and thank you so much for having me! I have this great project i'm working on involving 30 orange pi zeros. You see SD cards are expensive when you need to buy 30 of them so I have been trying for about a month now to make armbian work without the SD card. The idea is to boot into the os get a few things running and then remove the card and boot another pi. I have tried creating a ramfs mount and copying/mounting (what I believe are) all the requirements and then using chroot. But that doesnt work at all. I'm imagining that outside of chroot services are still running and once they cant write to some file…

I'm using g_ether to connect OrangePiPc+ to network over USB OTG. On legacy kernel, that was giving 140 Mbits/sec IN (download from network to OrangePiPc+) and 170 Mbits/sec OUT.

Hi, I want to use g_ether on NanoPi Neo Plus2. For Neo Air, I have already figured out how to do this and I can see usb0 in config. But with armbian 5.85 (4.19.38-sunxi64), the same instructions fail at sudo ifconfig usb0 up with the message "usb0: ERROR while getting interface flags: No such device". Could somebody tell me how to activate USB OTG on NanoPi Neo Plus2 and then use g_ether. I think the same holds true for g_serial. This could be an alternative, but I would prever ethernet connection. My target: Connect NanoPi Neo Plus2 with NanoPi Neo Air via Ethernet Thank you for your help! Steps I followed for g_ether:
