I have two Odroid C2s. One I have been using as NUT server for Eaton UPS. Today NUT clients report no connection. What seems to be the problem is the C2 (this happens with both, same SD card) are not seeing devices plugged into USB ports so the USB connection to the UPS is not working. I have verified the Eaton and USB cable are fine. I regularly update the C2 I wonder if a recent update has affected the USB port functioning? Any way to troubleshoot? I tried a few USB flash drives and then lsusb but none are seen.

Hi, I broke my /boot on eMMC and my Beelink GT1 is in boot loop. I can't configure u-boot to boot from the SD card to reinstall it. Can you help me reconfigure u-boot to boot from the SD card?

Hi, I tried to migrate my odroid C2 form corelec to armbiam bookworm 6.1.6.63... but i'm having some problems with network... i need to fix on switch the limit bandwith at 100mb/s even impossible to have network... When it's ok, if i tried to force config with ethtool (network freezes everytime)... and in every case, after some hours.. the network freeze.. So i'm looking for an armbian with a good stability and not too old.. Regards,

Hi, I downloaded the jammy xfce image for ODROID C2 today: MD5SUM 033fbc0babb56db5388b4c707a2fc0ce Armbian_23.11.1_Odroidc2_jammy_current_6.1.63_xfce_desktop.img.xz After flashing it onto my SD card with xzcat and dd, I tried to boot with my Odroid C2 ending up with this error message: ALERT! UUID=75e23441-f5ee-4479-a484-7060ccd898ae does not exist. So I put the SD back into my PC and checked with gparted: the UUID of the partition that I have on my SD card seems to have exactly the UUID that was not found. In fact the boot until that error message lastet quite long, so I expect that the timeout is not too small. Does anyone have an idea? Thanks!

Hi there, I have a working armbian jammy on my odroid c2, but I'm unable to get SPI to work. I tried to load the three as described in the odroid wiki (https://wiki.odroid.com/odroid-xu4/application_note/gpio/spi#tab__odroid-c2😞 sudo modprobe spidev sudo modprobe spi_gpio sudo modprobe spi_bitbang ...and that works, but unfortunately no device file is created. I believe SPI needs to be enabled somewhere additonally. In the "armbian-config" hardware section, there is only an entry for the odroid n2, which does not help/work for me. Are there any other hints somebody can give me to make it work? thanks a lot! sg

Hello Today i have a problem, which i had sometimes randomly. But today i'm at home, so i can connect the odroid via hdmi port. The error message is: kernel panic..... sorry, but i only can make a picture from the monitor. This is the picture: thank you a lot

Hello experts I'm a newbie and use my ofroid as server (mysql, iobroker, go2rtc) This need a lot of ram. So i try to reduce all service which i don't need. I disabled the gui (desktop) and ise only ssh. I use zram to be faster. Is there any other service which i can deactivate?

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
