Hi, Recently I reinstalled system on my Odroid C1+ from older Ubuntu with original 3.10.107 to newest Armbian with kernel 6.12.44. Generally it works quite well but I see a lots of stalls detection warnings in logs: Thu Oct 9 02:00:26 2025] rcu: INFO: rcu_sched self-detected stall on CPU [Thu Oct 9 02:00:26 2025] rcu: 0-....:

I figure I'd make this a new post. Thanks to @Markus_ and @Igor for their help. I'm still trying to get wifi module 3 working, but I'm happy to at least have an up to date C1 image. git clone --depth=1 --branch=master https://github.com/armbian/build cd build mkdir -p ./output/debs wget -c -O ./output/debs/linux-u-boot-current-odroidc1_23.02.0-trunk_armhf.deb http://apt.armbian.com/pool/main/l/linux-u-boot-odroidc1-current/linux-u-boot-current-odroidc1_21.02.3_armhf.deb ./compile.sh CLEAN_LEVEL= BOARD=odroidc1 BRANCH=current RELEASE=jammy REPOSITORY_INSTALL= BUILD_MINIMAL=no BUILD_DESKTOP=no KERNEL_CONFIGURE=no KERNEL_ONLY=no COMPRESS_OUTPUTIMAGE=sha,gpg,img ls ./output/images u-boot has not been able to be built for a while now (last supported image was focal and 5.x kernel). Step 4 copies the last good u-boot to ./output/debs which is created in step 3. Change current in ./output/debs/linux-u-boot-current-odroidc1_23.02.0-trunk_armhf.deb to edge to use edge kernel. Also change build number 23.02.0 to current build number. Step 5 does build without prompting. Change BRANCH=current to BRANCH=edge to build edge branch. If all goes well you should see image with step 6. Issues: reboot not working. Headless, no HDMI. No wifi at this point, just wired. Current branch with 5.x kernel corrupts SD. I found this build totally unusable.

Hi. Looking for help. I have uploaded Armbian v6.12 Desktop Ubuntu to a card and run on my device. You can see in the screenshot (video of the boot here: https://drive.google.com/file/d/1_1dm1rP33tbYISPUsta7nZV1eKPy3Plq/view?usp=drive_link) that some rubbish is displayed. I would also add that the device is sending a signal that is only displayed by the TV. No other monitor in the house is able to display anything that is sent from the device. This is even stranger, as when I upload the old ubuntu 18.04 to the same card, the device connected under any display displays my desktop. Any suggestions or suggestions? Maybe an older version? I want to make myself a RetroPi from the device, but that requires something newer than the old ubuntu.

Good day to all, please help. How can I install the ath9k_htc driver. Information: v25.5 rolling for MXQ running Armbian Linux 6.12.20-current-meson Packages: Debian stable (bookworm) - lsusb: Bus 001 Device 004: ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n 1) apt-get update & apt install firmware-ath9k-htc reboot -- plug usb wifi system freezes reboot apt remove firmware-ath9k-htc system work. dmesg | grep -i usb dmesg | grep -i firmware Please tell me how I can fix this? Thanks in advance for your help.

I finnaly found it on google Here is the link: https://drive.google.com/file/d/1gVU-iGhoYALZNok6RMkUzWg0BhXTrWCt/view?usp=drive_link

Hi, Armbian_21.02.3_Odroidc1_focal_current_5.10.21 how do I find out which number do I need to provide to gpio export command? Let's say I have physical pin 16, which is labeled by the manufacturer as `GPIOX.5` or `102`. But that doesn't work with Armbian: echo 102 > /sys/class/gpio/export [ 1602.030617] export_store: invalid GPIO 102 How do I know the value to provide for /sys/class/gpio/export? # cat /sys/kernel/debug/gpio gpiochip1: GPIOs 413-428, parent: platform/c8100084.pinctrl, aobus-banks: gpio-416 ( |TF_IO ) out lo gpio-417 ( |usb-hub-reset ) out hi gpio-426 ( |c1:blue:alive ) out hi ACTIVE LOW gpiochip0: GPIOs 429-511, parent: platform/c1109880.pinctrl, cbus-banks: gpio-456 ( |regulator-tflash_vdd) out lo gpio-470 ( |PHY reset ) out hi ACTIVE LOW gpio-482 ( |cd ) in hi ACTIVE LOW gpio-492 ( |reset ) out hi ACTIVE LOW Thanks

Are there any images for the C1? The archive download link is broken.
