  1. Right after booting Armbian_20.05.4_Odroidc4_focal_legacy_4.9.224.img on a SD card and then running apt update && apt upgrade -y leads to this "Operation not permitted" error message. Not sure if that's important. After the upgrade the board still reboots and comes back online. Processing triggers for systemd (245.4-4ubuntu3.1) ... Processing triggers for man-db (2.9.1-1) ... Processing triggers for libc-bin (2.31-0ubuntu9) ... Processing triggers for ca-certificates (20190110ubuntu1.1) ... Updating certificates in /etc/ssl/certs... 0 added, 0 removed; done.
  2. Update: reboot issue on SD card using Armbian_20.05.4_Odroidc4_focal_legacy_4.9.224.img cannot be reproduced
  3. Hello, I have just installed Armbian_20.05.4_Odroidc4_focal_current_5.6.18.img on my Odroid-C4, and encounter the same issue. The board doesn't come back up after rebooting. The ethernet controller is blinking in an interesting way. The right orange NIC LED blink about 5 times, then green and orange LED blink once together. This continues this way. The screen is not enabled after the reboot. Unpowering the board helps to reboot. The last thing you read from the screen before it turns black was: Reached target Reboot. I am using a micro SD card, Samsung Pro 32G. Let me know what inf
  4. Can you explain how you achieved this? I have tried a couple of steps including https://obihoernchen.net/1416/odroid-xu4-tune-network-and-usb-speed it doesn't seem to affect performance significantly when copying files from Win to HC1 through 1GE. It averages 55Mbytes/s which is think is too low. The same disk connected to my Odroid, I used with an USB/SATA cable before attached to my Win machine, the disk takes easily 130MBytes/s. I have tried that same disk with a rock64 (no tuning) and that same USB/SATA cable and Samba, it was twice as fast. I timed copying the same ~100GB of files.
  5. The issue with sda vs sdb didn't come back since I am using the oversized power supply. I got a multi-meter and measured the voltage under normal conditions, when the HC1 is loaded with compiling code and used one of my utilities to create lots of files keeping the disk busy. The voltage stayed in between 5.19 and 5.17. I noticed that my switch suddenly indicated that the Ethernet connection from it to HC1 is only of 100Mbit (orange light). I unplugged the cable and it changed back to 1Gbit. A little after it happened again. I am actually running Samba on the HC1 and indeed the con
  6. My understanding is, when the connected device tries drawing more amps, than the PSU under specified voltage can provide, the voltage collapses. My PSU from Amazon (https://www.amazon.com/gp/product/B01K0608A0) have 20W, if the HC1 under some circumstances draws more than 4A the volts have to go down, since its max is 20W (thinking about the power law). I will buy a multi-meter and do the measurements suggested. The one HC1 connected the Meanwell PSU didn't show the issue yet. Do know, I am not suggesting this 150W PSU as a final solution.
  7. Ok, thanks. I will find out if my psu are the reason. I don't have the tools to measure my PSU's performance under load. Yet need to read through the add'l information. Meanwhile, I got an LRS-150F-5 and changed over 2 of 3 HC1. It provides up to 22A. As you can see the cables are thick copper cables too.
  8. Hi, I have 3 Odroid HC1. All have a 2TB SATA disk attached. I am using Armbian_5.35_Odroidxu4_Ubuntu_xenial_next_4.9.61.img, and the armbian-config to copy the rootfs to the SATA disk. I have used ext4 and btrfs. Actually used btrfs from the start, but I got some weird error after running the HC1 for a couple of days, so that my open command, would return -bash: /sbin/blkid: Input/output error on any input. This is just an example. Didn't really know what was going on, I rebooted, and then could not login through ssh anymore. I assume rootfs gone, and reinstalled the HC1 again, copied over roo
  9. Thanks for your feedback. I wasn't looking for a "backup" solution rather interested to find out how many disks can I operate permanently using that one USB3 port of the ROCK64. I only figured I I had to solder in order to use the board to just address two disks instead of using RAID, when I had in my hands already. I was expecting some kind of switch or jumper.. Well I should have read the manual. Since RAID1 is the default, and I didnt find anything about this board here, I shared. The board already made it into the trash. I am waiting for these cheap usb3-sata pcb boards.. https://www.amazo
  10. I found this thread very interesting. I am experimenting myself with several different NAS options. Today I connected a Cubie HDD RAID sub-board to a Rock64 and two HGST travelstar 7.2k 1TB each. I copied over some 100GB using the samba server that just comes along with Rocks Linux rock64 4.4.77-rockchip-ayufan-118 For large files peeks were at 112MB/s when I copied over from a Win PC through 1GE, but kept a constant rate over 100MB/s. The Cubie sub board uses RAID 1 per default. I tried the copy process again and disconnected one of the disks. Just took it off. Active
