Hello i have armbian on a 64gb sd card. The card works not so good and has 64gb i would like to move my full distributuion with all configs(wireguard, ssh, ftps, iobroker, ufw, etc) on a new 32GB card. how can i transfer it without losing data? Thank you!

Hello I tried to shrink my sdcard (64gb, 17gb in use) and copy it to a 32gb card. I found a tutorial, but it don't work I fownloaded gparted and create a bootable device. The instruction 1.resize2fs /dev/sda1 [new size of the partition] in my case the original card is sdc1 2. Copy the shrinked device to the new device dd if=/dev/sda of=/dev/sdb In my case dd if=/dev/sdc of=/dev/mmcblk0 Is it really correct to use it without the "1" ? Sda, not sda1? However It didn't work.... Gparted gui shows me, that the original sd card has the original size 58.24gb. But I shrinked it to 27gb..... with resize2fs /dev/sdc1 27000M So I use gpated gui, by right click on device and select change volumesize. This worked, now I shrink the partition to 17gb. So looks good. After this , i tried dd if=/dev/sdc1 of=/dev/mmcblk0 to copy the partition. The odroid not boot, when I insert the card. Thd card hasn't a partition table, maybe this is the fail. So I do it again, but create a partition on the new sdcard, before i copy the old files on it. When I copy the files with dd, i will lose the partitions table. What is the fail Should i try to copy the full card to the new card Remember: on the new card is one shrinked partition with my armbian (17gb) and the rest of the card isn't as a partition. Thank you

Hello. I use jammy ambrian on my odroid c2. In this is a 64gb sdcard. 60% of the card is empty. Can i create a automatically backup on the card? It would be nice to restore the fullsystem if something go wrong and the system crah. At this time i crate all 4 weeks a full sd backup on my other computer. but it need a long time, because the full 64gb will be safe as a .img file, which i can restore. Is there a solution to get a smaller zip file, withe the full system???? Thank you a lot. If the fully system zip is not to great, i can upload it on my cloud..

Hi, So I found out the hard way that neither jammy nor bullseye builds for odroid c2 actually allow ssh at first boot My board is headless, but has a wired connection to my lan and always gets assigned the same address. Which file or files do I need to edit to ssh into it without having to do initial setup first, please?

Hello I use a odroid c2 und create a full img backup. Can i use this in a newer odroid like too? I have some programms etc on it and don't want to reinstall it.

I've tried a few images of the latest builds. None of them start. Odroid starts to power the screen and I see blinking lights, but screen goes dark and it seems to cycle like this. I use USB power for it and a powered hub (so basically no power output to USB dongles, etc.)

Hallo my odroid C2 shutdown during the night. i can see it always on the next day, when the ssl connection is disconnected. Is there any log file, where i can see, if there was any problem? thank you

Hello I use armbian on my odroidc2 on the devic is lamp, for a mysql and php server. Now i tried to install composer. The installation works great, but i can't use any scripts from vendor folder. The directory of my php file: /var/www/html/terminal/includes/helpers/my_php_file.php the code in my php file require_once(__DIR__ . '/vendor/autoload.php'); The code means the vendor directory has this path: /var/www/html/terminal/includes/helpers/vendor/autoload.php But thats not correct. I searched and found the correct path of composer it's: /home/user/vendor/ So i tried to make a folder-shortcut in my www/html/ folder, but i can't use it because permission denied. Next idea: i fix the code in my php file include '../../../../../../home/odroid/vendor/autoload.php'; now it would be found, but i get the same error: Warning: include(../../../../../../home/odroid/vendor/autoload.php): Failed to open stream: Permission denied in /var/www/html/terminal/includes/helpers/backup_DB.php on line 26 what's the correct way to youe composer with autoload.php and something more?

Hello I want to get cpu and ram infos via bash command. So i use this for temperature: For the cpu usage i needed a long time to find a solution. now i found this: echo $[100-$(vmstat 1 2|tail -1|awk '{print $15}')] For the free ram usage, i will use free --mega My question Are this command correct? the cpu command line is really new for me... does it takes a lot of ressources, if i use this commands every 2 seconds to get a real time listening? i need to write it in a database to get a graphical solution. Thank you for your help

I have an odroid-c2 with eMMC module flashed with Armbian_23.02.1_Odroidc2_jammy_current_6.1.14_xfce_desktop When viewing youtube containing word composed of non-latin characters, it shows a funny symbol for each character. How do I install the proper language for this?

I have an odroid-c2 with eMMC module flashed with Armbian_23.02.1_Odroidc2_jammy_current_6.1.14_xfce_desktop I have the following connected to the USB ports. 1) USB to audio headphone/microphone jacks 2) Wifi keyboard dongle The odroid-c2 is connected to an HDMI monitor with speakers I've been manipulating the settings for Pulseaudio and I could not get the audio to output to the monitor speakers. I could hear audio from the USB to audio jack connected to headphones

I tested the latest available Armbian image (minimal installation) on my odroid C2 via SD card. have available an 16gb hardkernel emmc card on which I had ubuntu 20.04 installed and running. But by burning the image with etcher (the same procedure as with the SD image) the odroid is unable to boot. Black screen, solid red led, and nothing else. I waited more than 30 seconds, I tried to disconnect keyboard....I waited more than 30 seconds, I tried to disconnect keyboard I have repeated the procedure through the SD and it works correctly. When I do it through the emmc, the system does not boot. When I use the SD card, the Emmc card is obviously disconnected, and when I use the emmc, the sd card is disconnected. I think u-boot has something to do with it https://redirect.armbian.com/region/EU/odroidc2/Jammy_current_minimal I apologize to the people mentioned above. I've read the forum a lot and thought they were the right people to respond to. @Igor

Hello, i tried to set up a little samba server with armbian on a odroid c2. If i use only the sd card, without any external storage, the system works fine, but if i connect any usb storage to the odroid c2, the system is booting into a bootloop or stops booting If i connect the usb storage after the first bios display, the system boot is fine. I think, the bootloader is trying to boot from the usp storage after detecting this, so is there an option to modify the bootloader, so it is only trying to boot from the pluged in sd card?

I’m running an Odroid C2 and trying to drive a 14.9" 1280x390 60hz LCD marquis display. On a Pi I can change the boot config files to the following and the display works like a champ. [HDMI:1] hdmi_group=2 hdmi_mode=87 hdmi_timings=1280 0 8 128 64 390 0 1 3 24 0 0 0 67 0 42009500 8 On the Odroid running Armbian 22.11 Jammy XFCE I tried changing: /boot/armbianEnv.txt adding display_autodetect=false hdmimode=1280x390p60hz I had no joy with this change, it did not modify the display output. I love how fast and light Odroid is with Armbian, it is really snappy, but I need some help stretching out this display. Any help pointing me in the right direction would be greatly appreciated, I already threw you $5 to take a look @Igor https://paypal.com/donate/?hosted_button_id=A2AM5NWLVENF2&source=url

I have a Waveshare 3.5inch RPi LCD (A): https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A) Does somebody have this kind of LCD running on a Odroid C2? Is there a step by step? Because the Waveshare or Odroid Wiki is over my head 😟

Hi. I want to use CAN interface on ODROID C2 board. I use external CAN-bus controller like MCP2515 via SPI interface. So, i need to enable SPI and CAN-bus peripherals and in kernel. So, could someone explain me how to do that? I know about device tree, but don`t know what to do. Just give me some guide links about device tree management, any examples, etc.

Hello Guys, i am running an Odroid C2 with the latest Armbian based on debian Bullseye. As disk i am using an 8GB emmc flash drive. For longlive reasons i am thinking about to reduce the read or more important the write access to that drive. I know, that every SD card and also every EMMC flash drive got a certain amount of write access and then its dead... So i am ask you what can i do to reduce read/write: - move logs to external usb? - activate ZRAM? - disable cache...? - tmpfs? I am just at the beginning of this, so kindly let me know if you guys have some well know hints. Thanks JM

I have just downloaded desktop Armbian 22.08 Jammy XFCE on my Odroid-C2 and it works fine on a 1080p monitor. I need it to work on a different monitor though so I have added the following lines to /boot/armbianEnv.txt display_autodetect=false hdmimode=1680x1050p60hz and added hdmitx=forcergb in the bootargs (which I copy/pasted from /boot/boot.cmd) but it has no effect. My monitor works with these parameters on Hardkernels Ubuntu 18.04 image. What else do I need to do?

I use DietPi on my Odroid C2. I post here because the developer mentioned that the DietPi image is based on the Armbian kernel and he suggested posting here. When I attach the R5 to a USB port of my Odroid C2 it is not recognized. lsusb and dmesg do not show it. On my Ubuntu 22.04 PC it does show up. Looked around and finally found an old post on this forum that mentions a bug with the C2 in recognizing USB devices. The mentioned workaround is to add a second USB device and reboot the device. I added an USB drive and both are now recognized, initialized and working after a reboot. (When removing one of the devices it again doesn’t stick after a reboot.) I can not find more information on this. It seems this problem isn't solved? Regards, Joost

I would like to permanently change at start up the UART permissions of /dev/ttyAML0 to give user, read write permissions always. I can do this with the usual "chmod" command but this gets reset after every boot and sometimes also during normal operations. Can somebody direct me to how this can be done please? xuraax
