I believe you likely have outdated version of the package. Here is the latest changelog entry for Ubuntu Noble. If you are using an older version, consider upgrading. If you are on bookworm you might want to consider the backports pocket. Or you can think about simply applying above patch locally.

Hi friends, I have good news, I found the Maskrom pin and managed to solve the problem with my MX10 box! By grounding the pin at boot time, it was able to boot from the sdcard and I used Multitools to burn a minimal Armbian image, after that it worked! My modified system, that uses the legacy kernel, only works the boot from sdcard, I tested it by burning the image and using the armbian-install command and it doesn't work! Even in maskrom mode the rkdeveloptool commands didn't work! These emcp memories are complicated, and this is 1.5Gb RAM and 8Gb of storage!

Are you trying to copy the rootfs of the system you are currently booted into? That won't work. You need to boot a separate installation, the filesystem you want to dd should not be mounted. You didn't really say what went wrong, by the way.

https://github.com/alexl83 and https://github.com/chraac are listed as the maintainers for the Opi Z3

Okay, so I ran a little experiment to verify that it's not about mocp but rather something about the file or file system: $ cp -a /mnt/music/_INCOMING/Malukah\ -\ The\ Dragonborn\ Comes\ \(2017\)/01\ -\ Awake.flac 01.flac Segmentation fault The resulting file contains 9175040 Bytes instead of the expected 9593429, so is truncated. Consequently I also see the corresponding dmesg output parrots what I showed before. So it's about exfat, it appears. Prior to the upgrade did I move the file over to an ext4 partition as well (as I guessed it would be impossible with the 6.12.30-current-sunxi kernel). Copying that around, including _to_ the USB key doesn't seem to cause any issues. I'll see if I am able to figure out how to get the clusters of that particular file. Perhaps it becomes reproducible elsewhere with a (trimmed down) disk image? 2025-07-06_dmesg.txt

@Ryzer attached is the lightly redacted log (removed user and hostname; one mount point now shows as $HOME, because I simply used this instead of manual manipulations: gzip -ckd /var/log/armbian-hardware-monitor.log.1.gz|sed "s|$HOME|\$HOME|g; s|$USER|username|g; s|$(hostname)|host|g; s|$(hostname -s)|host|g" The log is with the older kernel booted, which didn't exhibit the issue. Going to try the other one now. Please note, the actual armbian-hardware-monitor.log was empty (i.e. had been logrotate'd). debsums gives: $ sudo debsums -cs /etc/issue /etc/issue.net /etc/os-release /usr/share/doc/base-files/changelog.gz debsums: missing file /etc/default/armbian-motd.dpkg-dist (from linux-bionic-root-next-cubietruck package) debsums: missing file /etc/default/armbian-ramlog.dpkg-dist (from linux-bionic-root-next-cubietruck package) debsums: missing file /etc/default/armbian-zram-config.dpkg-dist (from linux-bionic-root-next-cubietruck package) /etc/skel/.config/htop/htoprc debsums: missing file /etc/update-motd.d/99-armbian-point-to-faq (from linux-bionic-root-next-cubietruck package) Will remove linux-bionic-root-next-cubietruck then reboot. But as you can see from the reference to bionic, this system isn't exactly freshly installed :-D armbian-hardware-monitor.log.gz

This would be very very hard. Would likely take years and would likely never achieve full functionality. If you have access to the source code for the firmware that comes on the device you would have a chance.

My Banana Pi M2+ is running quite fine on noble but something is amiss with bluetooth. bluetoothctl never shows any devices even when scanning for them and there are plenty of devices within arm's length. I am hoping for your help in diagnosing and ultimately fixing the issue. Logs:

Right, judging by only one instance in the topwise a721 dts: [ 3.446799] sun4i-drm display-engine: No panel or bridge found... RGB output disabled I am inclined to think that is configuring the panel. This can be validated by checking ls /sys/devices/platform/display-engine/drm/card0 or looking for simple-panel in lsmod. I suspect it may be a pin-muxing issue where the pins are not being set. now what these are set depends on the lcd panel type which could be LVDS or a parallel panel. I believe it should be LVDS but just wanted to confirm. Now the A10's pin controller section within the dtsi does not map out as many function compared A20 dtsi, so within the topwise a721 dts under the pio node the display pins need to be declared and their function stated. Secondly attach the pin control handle to tcon0. For example: &pio { lvds0_pins: lvds0-pins@0 { pins = "PD0", "PD1", "PD2", "PD3", "PD4", "PD5", "PD6", "PD7", "PD8", "PD9"; function = "lvds0" }; }; &tcon0 { pinctrl-names = "default"; pinctrl-0 = <&lvds0_pins>; };

A few days ago I had an issue with a successfully running Armbian installation running from the NVME of my Orange Pi 5 that suddenly developed an issue with nothing being shown on my TV. So after seemingly not being to identify the problem, I started again, wrote the image to an SD card and then moved the installation to the NVME drive using armbian-config utility. So now that I have a set-up that works again, I want to instigate a more belt and braces approach and create an image of the NVME installation using GZIP to compress the image file and decided to use the DD option from terminal. Having tried well over a hundred different combinations of commands, I am unable to get things to work. I either get errors of Not a directory, No such file or directory or Is a directory The output of lsblk is NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS mtdblock0 31:0 0 16M 0 disk mmcblk1 179:0 0 59.5G 0 disk └─mmcblk1p1 179:1 0 59.5G 0 part zram0 252:0 0 3.9G 0 disk [SWAP] zram1 252:1 0 50M 0 disk /var/log zram2 252:2 0 0B 0 disk nvme0n1 259:0 0 238.5G 0 disk └─nvme0n1p1 259:1 0 238.5G 0 part /var/log.hdd So in order to create the copy of the NVME installation, that is only taking up 13gb of the 238Gb total, to the root of a 64Gb SD card, completely empty and formatted to EXT4 via gparted, using the information above, can anybody see where I am going wrong. A few typical examples of command structures that I have tried are: sudo dd if=/dev/nvme0n1 of=/dev/mmcblk1/armbian.gz conv=sync bs=64K | gzip --stdout > bs=4M status=progress dd if=/dev/nvme0n1 conv=sync bs=64K | gzip --stdout > of=/dev/mmcblk1/armbian.gz dd if=/dev/nvme0n1p1 conv=sync bs=64K | gzip --stdout > of=/dev/mmcblk1p1/armbian.gz bs=4M status=progress This is the general template that I initially followed from a website dd if=/dev/SOURCE conv=sync bs=64K | gzip --stdout > /path/to/file.gz I've researched the use of the DD command until I am cross eyed.

Note you can provide more diagnostics with armbianmonitor -u and then pasting the link to the report here. Maybe something could have gone wrong in the unpacking process or linger system components causing issue? Just trying to rule out all other possibilities before putting it down to regression. I haven't encountered this on my system or aware of anyone else having the same problem. That's not of course to say their could be a problem.

Tried to check the integrity: $ sudo fsck.exfat -n -v /dev/sdb1 exfatprogs version : 1.2.9 label: MUSIC sector size: 512.00 B cluster size: 256.00 KB volume size: 2.26 GB /dev/sdb1: clean. directories 2083, files 32997 So it's fine. Just built exfatprogs from main just now (52b816e). For good measure I'll boot up a Windows and retry a file system repair there to see if any errors show up. Curious, I just noticed the volume size appears to be wrong in the above output: /dev/sdb1 501G 390G 111G 78% /mnt/...

Hi folks, I'll give these a try. Sorry for the brief silence. I'll perform an integrity check. I did. I used --follow and had it run in another Tmux window. The excerpt above was retrieved this way. There's about a minute and a half of (no) dmesg output prior to the output at 90829. Will do. Hasn't that been pretty much proven by downgrading just the kernel and friends? And it'd be quite hard to test a clean image, but if the other methods fail to narrow it down, I'll do it. Have to see if I can find one. This system has run for a long time, but debsums should typically be enough to tell if something is amiss, no? So rather than a clean image I'd suggest to attempt another upgrade to see whether that helps, no? I have not. It's a good point, though. However, it'd still be a regression, no? Again, the older kernel simply reads everything and the music plays fine. These are good points. I'll try with cat or so and perhaps mpv as well. If it's indeed an exfat issue there is no relation to the song or mocp. Will report back with some more information.

Would it be easy to port Armbian on the Pipo M6 Pro and integrate additional device drivers to provide support for the touchscreen, the front and back camera and the sound? https://www.geekbuying.com/item/Pipo-M6Pro-GPS-Android-4-2-RK3188-Quad-Core-1-6GHz-Tablet-PC-9-7-inch-Retina-Capacitive-Touch-Screen-2048-1536-2GB-16GB-319264.html Is this something feasible in the first place? Anybody out there who want to help me on this project?

dear Comose your are in the wrong topic this is not about rk3528 , please look at armbian forum for right please of rk3528 hallo Comose du bist hier am falschen ort , dies hier ist über rk322x board und nicht rk3528 , biite schaue in den anderen Bereichen nach rk35xx (Rk3518 / Rk3528)

I can do that but it does not provide any useful information on the subject in my opinion. Is there a way to downgrade to 25.8.0-trunk.313? According to this post, it might be useful to set the kernel option nvme_core.default_ps_max_latency_us resp. the DT overlay parameter pciex1_gen=3. How can the kernel (cmdline) option be set in Armbian? Regarding the DT overlay parameter pciex1_gen, should I follow this part of the documentation?

So, there is nothing more we can do here I think. Wait for rockchip to correct upstream.

Hello djmuted. I'm a german beginner. I have a Box Labeld Greva 8k Android 13 4G DDR3 / 64G emmc and CPU RK3528 from Amazon.de. She have an WiFi Chip EA6521QT . You have Compile it for 32bit Cpu RK322x . I need compile this driver for 64bit . It this possible? I have no idea how to compile it. Can you show me a way how I can compile it? I have Flashed armbian from this Site : https://github.com/fensoft/dq08-haos/blob/master/README.md and running HAOS & Gnome for Touchscreen . Works perfekt without Wifi. The power consumption 2.5W ( for Home Assistent Server Wonderfull) the Version is 5.10.160-legacy-rk3528-tvbox. Thanks

maybe this bug at Rockchip/mpp is relative : https://github.com/rockchip-linux/mpp/issues/855

Since U-Boot v2025.04 works very well on Orange Pi Zero v3 and has a shorter boot process time, if there was a possibility to switch to U-Boot v2504 for Orange Pi Zero V1, I would be grateful, as would probably other users of this SBC Regards

The issue appears to be two things. These two patches and the current defconfig(s) being used. drv-rtc-sun6i-support-RTCs-without-external-LOSCs.patch drv-rtc-sun6i-Add-Allwinner-H616-support.patch When I disable those patches and use my own defconfig everything works as it should. https://paste.armbian.com/tixixocubu The hard part here would be figuring out exactly what in the defconfig(s) are either breaking things or missing. Also if I disable those patches, what does it break on other units? I'm under the impression these patches were rejects from the original h616 bring up in mainline. But I could be wrong?

Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed.
