Hello, I try install armhf packets (piaware) from it's repo, what I do: dpkg --add-architecture armhf nano /etc/apt/sources.list.d/piaware.list change it to: deb [arch=armhf] http://flightaware.com/adsb/piaware/files/packages jessie piaware then apt-get update apt-get install piaware and have this error: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: piaware:armhf : Depends: tcllib:armhf but it is not installable E: Unable to correct problems, you have held broken packages.

Hi, I am on my third attempt at running armbian on my C2. 16GB eMMC (purchased through Hardkernel) card. The image is; Armbian_5.20_Odroidc2_Debian_jessie_3.14.79_desktop.img On the last two attempts I have followed the getting started guide and performed an update/upgrade after install; apt-get update apt-get upgrade All setup proceeded without issue. However, the C2 refused to restart with a steady blue light on the board (no heartbeat). This is my third attempt and so far I have not upgraded and have tested restart and shutdown a few times...all working well. Can you give me any advice on this issue? Should I wait for a new image?

Hi, I installed yesterday armbian on my Odroid C2. I would like to use an USB to serial converter but, the device is not detected by the system. When I plug the USB device, I just have this message in the kerner.log file and the USB device is not created : Nov 18 12:04:41 localhost kernel: [59003.780747] usb 1-1.3: new full-speed USB device number 13 using dwc_otg However, when I run lsusb the device is listed : root@odroidc2:~# lsusb Bus 001 Device 013: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Did someone already have this issue ? What do I need to install to get the device to work ? Let me know if you need more information.

Once apon a time I had the Armbian system working (though chrome was missing). I have since upgraded to the kernel 3.14.79 and the console videomode seems to have extra text that I can't see at the bottom of the screen where the prompt is. That is, I can't see when I type, I only see after I hit return a couple of times and the result scrolls up. I have customized my videomode correctly,I think, and all this used to work, so what should I do? Unrelated but... From what I can tell, there seem to be a lot of issues with this hardware on Armbian for lots of people. Wondering if I should just give up on this piece of otherwise awesome hardware and move on with my life? Is there anyone happily using this system on Linux as a desktop?

Greetings all. Today I tried updating my Odroid C2 to image 5.22 posted on Oct 22, 2016. And I got the following error during apt-get upgrade: Setting up linux-u-boot-odroidc2-default (5.22) ... /var/lib/dpkg/info/linux-u-boot-odroidc2-default.postinst: line 5: conditional binary operator expected /var/lib/dpkg/info/linux-u-boot-odroidc2-default.postinst: line 5: syntax error near `function' /var/lib/dpkg/info/linux-u-boot-odroidc2-default.postinst: line 5: `[[ == function ]] && setup_write_uboot_platform' I peaked at the code in /var/lib/dpkg/info/linux-u-boot-odroidc2-default.postinst contains #!/bin/bash source /usr/lib/u-boot/platform_install.sh [[ $DEVICE == /dev/null ]] && exit 0 [[ -z $DEVICE ]] && DEVICE="/dev/mmcblk0" [[ == function ]] && setup_write_uboot_platform write_uboot_platform $DIR $DEVICE exit 0 Which appears broken, so I updated it to: #!/bin/bash source /usr/lib/u-boot/platform_install.sh [[ $DEVICE == /dev/null ]] && exit 0 [[ -z $DEVICE ]] && DEVICE="/dev/mmcblk0" [[ $(type -t setup_write_uboot_platform) == function ]] && setup_write_uboot_platform write_uboot_platform $DIR $DEVICE exit 0 And the upgrade succeeded. Dunno where else to post this information. Hope it helps someone

Hi I'm wondering why chromium is missing from the ODroid C2 image when taking the non-desktop image and then adding the necessary packages to get a minimal X working? Planning to just build it from source, but wondering why it was missing from the core armbian distro? Is there a reason?

Please contribute if you're affected: https://github.com/igorpecovnik/lib/issues/499

Hello Forum, i am using a vdr headless server with 3 Technisat Skystar USB tuners for satellite television streaming. Before i used a raspberry pi 2 but because of limitations with its ethernet bandwith i went to odroid c2. System is now armbian with self compiled vdr with vnsi plugin, both out of git repo. System runs fine but after some hours (8h) a sporadic failure occurs and (USB?) system becomes unusable, To get the 3 dvb-s2 tuners running i increased the urb pool (USB request block) with kernel parameter "coherent_pool=6M" in boot.ini. I calculated that every of all 3 instances of driver needs about 512kB of USB buffer memory, without the option the first instance fails with error -12 (ENOMEM). At first i put an option "coherent_pool=32M" to test but it seemed that this was ignored without any message. I found a hint in another forum and tried 6M and that seemed to be taken and to be enough for my 3 tuner devices. My first questions is: what are the limits for this parameter coherent_pool and what is the default value ? Second: what can i do to increase stability of USB ? Here the syslog after some hours: WARN::urb_dequeue:780: urb->hcpriv == NULL; urb = ffffffc07a0c9000 status=-2 and then lots of driver and application errors because of usb action errors: dvb-usb2: i2c-error: out failed 68 = -110

hi, I installed latest Armbian (Debian/Jessia) as well as built Xenial Ubuntu (5.20 kernel 3.14.79 in both cases). Board is Odroid-C2. As i have a Wifi USB - TP-Link TL-WN823N I need to build a driver for it as it is not included in kernel. Found instructions at Armbian documentation: http://docs.armbian.com/User-Guide_Advanced-Features/#how-to-build-a-wireless-driver but after starting with make ARCH=arm64 it fails with error that ... xen.h is missing. Does anyone have recipe for success ? Below is failure log on Debian-Jesse (exactly same issue on Xenial-Ubuntu).

Hi everyone, I've just installed Armbian on my Odroid C2 but I'm struggling running Iceweasel Firefox. I have a segfault everytime even in safemode, any guess of the problem (I made both apt-get update & apt-get upgrade). Thanks !

Hello.. What kernel version is used in armbian? Hardkernel latest release is 3.14.80 .. armbian uses 3.14.74. ( i suppose the versioning is the same only older kernel is used on armbian). Is it possible to add harkernel repo and upgrade the kernel without braking anything? Thank you,

Can the c2 RTC be used with armbian?

Hi everyone I've tried to flash "armbian*.raw" downloaded from here: http://www.armbian.com/odroid-c2/URL] the "Jessie desktop" version. I have a panasonic 16gb micro SD card They say that the ".raw" image can be written with Rufus...but they don't explain what kind of settings should I have to use. I've tried many of that settings bit with no result...the program always says "DONE" but when I put it in the odroid there's no boot. Does anyone know a "how to flash" please??

Hello, I tried to build a fresh image for the Odroid C2, but always fails with the u-boot.bin. The error is equivalent to the Issue #452 on Github. Anyone else with this problem? Thanks in advance.

I do have problems on my two Odroid C2 after "apt-get update" and "apt-get upgrade".

I have a 8gb SD card and 64gb eMMC. I want to put Armbian on the SD and use eMMC for high disk usage activities. When using the eMMC it will always boot of that device. You can alter the boot.ini to get it to boot off the SD once it reads the boot information from the eMMC. I installed Odroid Mate on BOTH the eMMC (to get the boot partition created) and the SD I can get it to use the installed OS from the SD card. Original Odroid boot.ini from eMMC: setenv bootargs "root=UUID=74ce0af9-be77-4ebe-9308-c06feb2ecef9 rootwait ro ${condev} no_console_suspend ... # Booting fatload mmc 0:1 ${initrd_loadaddr} uInitrd fatload mmc 0:1 ${loadaddr} Image fatload mmc 0:1 ${dtb_loadaddr} meson64_odroidc2.dtb I am changing bits and pieces together I have found online. setenv bootargs "root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait ro ${condev} no_console_suspend ... # Booting fatload mmc 1:1 ${initrd_loadaddr} uInitrd fatload mmc 1:1 ${loadaddr} Image fatload mmc 1:1 ${dtb_loadaddr} meson64_odroidc2.dtb With only four changes – it works to boot Odroid’s image from the SD card. The problem comes when I want to boot Armbian rather than Odroid’s image. I changed the boot.ini like this: setenv bootargs "root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait ro ${condev} no_console_suspend ... # Booting fatload mmc 1:1 ${initrd_loadaddr} uInitrd fatload mmc 1:1 ${loadaddr} zImage fatload mmc 1:1 ${dtb_loadaddr} dtb/meson64_odroidc2.dtb Essentially keeping the original changes I made, plus the other differences I could see from Armbian’s boot.ini, which add a couple more changes. With this boot.ini and Armbian installed on the SD, the Odroid C2 will start blinking the blue heartbeat light but nothing on the screen and not responsive to any ping or SSH attempt. So I have no idea what it is doing (if anything). Has anyone ever succeeded in doing this? Since I can get it working with Odroid’s image there is hope, but I really want to run Armbian as I think there is more development being done on this build.

Folks, I've flashed a 16GB eMMC 5.0 card with Armbian and it's booted up on a Rev 2 Odroid C2, but it only gets as far as the attached picture shows. I've left it overnight to see if it gets any better and it's still stalled. The blue LED ("disk" activity) is a steady 2-beat heartbeat which to me sounds like it's stuck trying to seek whatever happens next. I wanted to leave it overnight and also post here before attempting to fix via rebooting, then re-flashing if I have to. Anyone see this before? Sorry this is my first go at Armbian and it's on a brand new device - I come from the mx6 world.

When I start the OS for the first time, the cursor is not visible, either at the command line or in the nano editor. I'm running the HDMI output through a HDMI->VGA adapter, which is then fed into my KVM along with the mouse and keyboard. The monitor is capable of 1920x1200, and it all works fine except for the cursor not being visible. I've tried various escape codes, etc. Nano never displays a cursor. When I log in via SSH the cursor is plainly visible. I'm trying to configure the WiFi, which doesn't seem to want to work if the ethernet is connected, so I'm stuck at the tty terminal. Any suggestions?

Hello, i bought my first odroid, and decide to install armbian. I download armbian from official server, and i try write os using rufus on Windows. I choose 'dd' and check raw file, rufus write image without error. When I plug MicroSDHC card, system starts, red led is on, blue flashing. From first minutes system have got big lag, I wait 50 minuts and do nothing in first boot. Last text on screen is **** Starting Update UTMP about System Runlevel Changes... [ OK ] Started LSB: PLEASE BE PATIENT AND DO NOT INTERRUPT THE FIRST REBOOT [ OK ] Started Update UTMP about System Runlevel Changes. *** I use Odroid c2 rev 2.0 20160226 and SanDisk ultimate MicroSDHC. What I have to do? I still waiting, and don't unplug power supply.

Still trying to get the wireless working... Followed directions here, and during the "make ARCH=arm64", I get the following: compilation terminated. scripts/Makefile.build:308: recipe for target '/Downloads/WiFi/rtl8192cu-fixes/core/rtw_cmd.o' failed make[2]: *** [/Downloads/WiFi/rtl8192cu-fixes/core/rtw_cmd.o] Error 1 Makefile:1278: recipe for target '_module_/Downloads/WiFi/rtl8192cu-fixes' failed make[1]: *** [_module_/Downloads/WiFi/rtl8192cu-fixes] Error 2 make[1]: Leaving directory '/usr/src/linux-headers-3.14.73-odroidc2' Makefile:584: recipe for target 'modules' failed make: *** [modules] Error 2 Now what???

I am using: Armbian_5.14_Odroidc2_Debian_jessie_3.14.71 I am a bit stumped....if I run with 3 network interfaces, everything is fine. If I add a fourth interface...the system locks up...even if the 3rd and 4th interface have no ip address. They just need to be live! I have tried 4 drastically different interfaces in case the device driver can't handle it. Anybody have any thoughts or suggestions?? THank you!
