Odroid N2/N2+

Good morning, after some time using armbian on my OdroidN2 with great success (got Nextcloud with working Talk installed, external USB, Minecraft server, nginx, LetsEncrypt, Netdata...) I encountered some problems I am not able to solve by myself: I bought a RTC battery and a LED power button to "finalize" my Odroid (hardwarewise), and to my surprise both did not work as expected. RTC: It says: chris@OdroidN2:~$ sudo hwclock hwclock: select() to /dev/rtc0 to wait for clock tick timed out cat /proc/interrupts |grep rtc ...gives me also no return (empty string), so i guess there is a module missing in the kernel : chris@Odroi…

Install of Armbian 21.02.2 Buster with Linux version 5.7.15-meson64 and gpiod package installed on the Odroid N2 does not work for gpiomon. The gpiod command gpioinfo and gpioget work fine. Gpiomon fails with message "No such device". Searching for hours I believe the issue is that interrupts have not been assigned to the gpiopins, so appropriate devices don't exist. Any information on when/how to get a fully functional gpiod and associated python package going. Python code using python3-libgpiod also fails on the line.request function with the same "No such device" error.

The images where applied with Balena etcher. Petitboot was removed as described. The PSU was included in the bundle (15V 4A). Odroid Ubuntu works fine. The boot process stops at: Booting kernel ... I tried the following Images (none of them works): Armbian Buster - mainline kernel 5.10.y Armbian Focal - mainline kernel 5.10.y What am i missing ? Any help appreciated.

Hi, I upgraded armbian on N2+ today... Apparently kernel was updated, I dont know how to fix this. Someone to help me ? Thanks

Hi all How can I enable the rtc clock in the Odroid HC4? I know nothing about device tree and overlays, but the Hardkernel Ubuntu image has an overlay to enable: wiki. I didn't find anything similar in the armbian image. Could be related to this this PR for the N2 model? Thanks

I recently upgraded from an Odroid HC2 to and Odroid HC4. I reinstalled the OS following the instructions on armbian.com, flashing onto a MicroSD. After migrating the apps (mostly dockers), I found that restic (backup tool) was generating out of memory errors and bringing the system to a halt in a way the HC2 didn't. This surprised me as it's overall higher specced, and the configuration was otherwise identical. After some troubleshooting, I realised there was no swap drive specified, and that creating a swap eliminated my out of memory errors. I'm not sure if the source of the "problem" is the swapfile here, but it at least…

Minor annoyance, but wondering if there's a way to fix this on boot ? It's happened on all releases i've tried (emmc) enough of an annoyance now to ask about it. i've tried setting various resolutions in the boot.cfg but that doesn't seem to make a difference? connected via hdmi When I first turn it on I see this; Then it goes to this Then, i see normal dmesg and it's all usable.

Hi, is there a way, how to check that image in download section is ok? I have Odroid HC4 with good PSU, both old and new card, flashed by Etcher and Rufus, keyboard plugged in USB, no SATA disks at the moment. I'm able to boot Focal 4.9 kernel (however with some errors after the boot). I've removed Petitboot with flasherase first, I've checked SHA checksum. Edit: File I've downloaded is: Armbian_20.11.6_Odroidhc4_focal_current_5.9.14.img.xz SHA: 9930f984eca2a72b3c22953ee6381c95da528b2a355dd9f429da38d1409f7b1f *Armbian_2 Any ideas what is wrong? Thank you.

Hi all. A few improvements have been made lately for the Odroid N2/N2+. HDMI sound for example. There are just a few little things I'd like to see happen to make it even better/perfect for desktop use, and for gaming when the GPU drivers for it are ready. Make HDMI resolution selectable in Armbian itself instead of in boot.ini. This would fix multiple issues. Like with mainline it always defaults to 4K on my 4K display whatever resolution I set in config.ini. The N2+ can work well at 1440p, but 4K is just too much for it. In legacy 1440p works when setting it in boot.ini. But can't be changed in Armbian itself. For gaming this will be a huge problem(on mai…

Hi all, I've been searching this topic for a while but haven't found a clear answer to my question. Running an N2+, I've noticed that sometimes, in dmesg, a process will be killed due to lack of ram, this is usually when, for example, plex is busy generating video thumbnails and bazarr is syncing newly downloaded subtitles for example. This isn't as common place as such but it does happen from time to time. My armbian installation (latest ubuntu server image with latest mainline kernel) is installed to an nvme ssd, so I was wondering if enabling zswap and disabling zram would be beneficial in this case? Or can both be used at the same t…

Armbian 20.08.13 Odroid n2 buster legacy 4.9.238 does not boot on emmc updated petitboot with pb-update, no effect! got back to Armbian_20.02.5_Odroidn2_buster_legacy_4.9.216, no problems there immediately freezed armbian updates with armbian-config, because my last kernel update did break my whole system.

Currently no /dev/watchdog device on N2 with -current and -dev armbian kkernel. But watchdog present in -legacy.

Hi, first post here. After upgrading Armbian on my Odroid-N2 to 5.8.13-meson64, I can no longer mount using autofs, neither manually nor via systemctl. The error message is: mount: /home/<mountdir>: unknown filesystem type 'aufs'. The Armbian Build Options information suggests that kernel builds include AUFS by default: AUFS ( yes | no ): Include support for AUFS Am I missing something? Armbian version is #20.08.6 SMP PREEMPT Thu Oct 1 18:51:27 CEST 2020

So, I've noticed there were some updates available, so decided to do so, now running 20.08.7 Focal / 5.8.13 kernel. Now, I did run the nand-sata-install when I first installed armbian a month ago to an external SSD and all's working perfectly. The thing is, a couple of weeks ago, even after this latest update and rebooting, the sbc won't boot up, I had to pull the plug and back about 20 times for it to boot. So this is what I found running dmesg.

Hello, I run armbian 20.08.3 on an Odroid N2 with a dongle wifi. I have upgraded the board from armbian-firmware full 20.08.3 to 20.08.4. After that the screen insn't recognize anymore (it's an AOC e2250Sda) and after some reboot it s doest start anymore. Have I to wait the nex update ? Thanks a lot

Hi, I am using the Odroid N2, and I have recently switched from the Hardkernel-supplied Ubuntu Mate, to an Armbian version with kernel 5. I was hoping to combine a homemade NAS using CPU accelerated LUKS-encrypted disks with a Kodi mediacenter, and the N2 seems to have excellent properties to do both. Installing these Armbian functions immediately fixed a few problems that Hardkernel's Ubuntu had (unstable BTRFS driver, and I also see no sign of the USB3 disconnect problems that Odroid used to have). However, this version has a problem to recognize audio hardware - in the GUI, I am unable to select HDMI audio or analog audio. - Fo…

Odroid-N2 using Armbian_20.08.1_Odroidn2_focal_current_5.8.5 I've recently got a "Connection timed out" issue. For instance, I can open files with nano, use htop, armbian-config, update and upgrade packages, but I can't reboot (everything over ssh). I'm having a feeling that the issue started when I tried to figure out if it's possible to get HDMI to work with my 4K TV when the HDMI cable is not plugged in at boot. In that case, I booted several times and chaged boot.ini with setenv display_autodetect "false", setenv hdmimode "1080p60hz" and setenv disablehpd "true" without success. armbianmonitor -u information is attached at the end in my post where this line migh…

Hi. I recently purchased a few DS18B20 sensors. I'm having troubles setting up 1-wire on the newest armbian: root@odroidn2:~# uname -a Linux odroidn2 5.8.5-meson64 #20.08.1 SMP PREEMPT Tue Sep 1 18:47:20 CEST 2020 aarch64 GNU/Linux My DS18B20 adapter is connected to "GPIOX_7(#)" as suggested on Odroid forum: https://forum.odroid.com/viewtopic.php?p=305664#p305664 Using the official Ubuntu 18.04 image with 4.9.230-76, I was able to find devices in "/sys/bus/w1/devices".

Hi, the lastest kernel update issues the following lines in dmesg output: [ 12.214293] meson8b-dwmac ff3f0000.ethernet: Failed to reset the dma [ 12.215002] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 12.223988] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_open: Hw setup failed Do I need to update the firmware as well? B.t.w. you may mention that armbianmonitor -u needs to be run as root, otherwise the fping check will fail.

TL;DR Where in armbian build system correctly can be make N2-only related changes: 1. /boot ext4 volume have to have symlink . as boot, can be created with command ln -s ./ boot 2. kernel env variable set in boot.ini contain part but it shouldn't. This substring need to be removed if btrfs choosen. 3. /boot ext4 partition have only 4 MB free. I am not sure but think it's too small; for example there no space to run update-initramfs -u. I think it should be larger, like 500 MB. Long: I want to run my oDroid-N2 with root on BTRFS filesystem. I use manual on armbian image build and did time ./compile.sh BOARD=odroidn2 BRANCH=cur…

For the second time today on my few-days-old Odroid N2+ build with Buster desktop I have a system-wide freeze. Blue LED is constantly on and there is no response to keyboard or mouse events. Was interacting with Plex both times but I only have Plex, Tautulli and Samba server set up. I'm loath to pull the power but 30mins in to the second freeze (I pulled the plug on the first one). What should I be looking for when I get it running again?

I am trying to build a compute cluster from Odroid N2. But seems like the core 5-6 does not speed-up the application at all. And the speed up is also not linear along the cores.

I've been trying this all day and I can't get it to work for me (focal mainline kernel 5.6.y) - I can start on sdd, change hostname, make it a static ip, reboot - works fine. As soon as I try to nand-sata-install and boot from sdd + system on usb it just disappears after the reboot. Pity, works fine with the legacy.

I'm trying to use a Pixel Qi screen with Odroid N2 running armbian. I've made EDID file myself and had it set in armbianEnv.txt like this: edid=0 disp_mode=1024x600 extraargs=drm.edid_firmware=edid/qi.bin But in nowhere it's loaded by the system.

On an Odroid N2 booting off emmc with latest Armbian (N2 version) and I seem to be experiencing systemd issues. That is, I am wondering about why dmesg outputs large amounts of lines like this: ...

I am trying the first releases of armbian on my new odroid n2 and would like also to test openmediavault which should be available with 3rd party option on armbian-config. But at the moment this software option is not available. Is there a reason for this, maybe the device is very new and not tested for the moment?

Was wondering if there is any plans to support the recently released ODroid-N2 sbc.
