  1. Any idea why 4.14 linux kernel don't work with mali drivers ? https://github.com/superna9999/meson_gx_mali_450/tree/DX910-SW-99002-r7p0-00rel1_meson_gx
  2. Hi I build ubuntu xenial with next kernel (4.13.....) and image don't boot https://pastebin.com/QHQfHHSa and I also can't boot debian 9 with next kernel https://pastebin.com/yXjWk5Wh Any idea where is problem?? all fine with dev kernels
  3. I'm using an Odroid C2 and need some newer software packages than those found in the Ubuntu 16.04 repositories, so I installed the legacy (3.14.79) version of the Debian server edition of Armbian, then upgraded it to Debian 9. I've installed xorg, lightdm, etc and now have a very functional desktop. However, I want to install a 3D CAD program that **I think** would perform better if I had 3D accelerated graphics installed. I'm a complete noob when it comes to 3D graphics drivers. I assume they're not installed, as I see this on my Orange Pi PC 2 running the desktop version of Ubuntu: $ lsmod | grep mali mali_drm 2732 1 drm 178255 2 mali_drm mali 123146 0 ump 29379 3 mali but nothing on my Odroid C2. I can't find the drivers in any directory on my system, either. How would I go about installing them? -Jim
  4. Hi everyone, thanks at first for all the efforts to maintain downloadable Armbian images. However, I am currently unable to execute a mainline Linux kernel, packaged as a .deb, that comes from the Armbian repositories. The current situation: Successfully tried Xenial default image (Kernel 3.14). Upgraded to next (Kernel, C2 board won't boot. Successfully tried Stretch next image (Kernel Upgraded to next (Kernel, C2 board won't boot. Tried Stretch next nightly (Kernel, C2 board won't boot. Also tried the dev images from the beta repository, C2 board won't boot. (Besides I am aware of the experimental character of the next and dev kernels. The board is an ordinary C2 one without any modifications and a decent power supply.) My problem: I need to compile the DRBD 9.x kernel module. To make things easy for me, I usually download the appropriate linux-headers-xyz package from the repository and compile the module. With the default kernel (Kernel 3.14), this is possible. Because the current next Linux kernel (Kernel won't boot, there is no chance for me to compile the kernel module mentioned before. From my perspective, there are two options: In some way I can get the linux-headers- file for the only working mainline kernel (see 2.) or I manage to prepare a kernel source tree for from the running kernel.
  5. hi all, as mainline kernel options for Odroid-C2 are still not ready (USB not recognising DAC unless externall HDD connected during boot) .. have just switched back to 'default' build. I noticed system to be much slower then usual .... esp. when involving any writes. SD-Card is Sandisk 16GB and is working very well in OdroidXU4 and NanoPi NEO. When copying a few 100kB file takes few seconds: time cp /usr/bin/ssh ~/ ; time sync real 0m0.012s user 0m0.000s sys 0m0.010s real 0m2.982s user 0m0.000s sys 0m0.010s I tried with 'dd' command to see how fast simple writes are going and got at best 200kB/sec .... Does anyone have suggestions what to do ?

  6. Hi, My first time attempting to use a nightly image in an attempt to get away from the legacy kernel. I installed Armbian_5.33.171007_Odroidc2_Debian_stretch_next_4.13.5.img on my C2, and it booted up just fine. Unfortunately, my primary use case for this hardware is a music streamer (and server), requires the ability to use Class 2 USB Audio, with (relatively) high-end USB DACs. I was unable to get the USB DAC to be recognized at all (did not show up in the ALSA devices listed by aplay -L, nor was it listed by lsusb.) I immediately reverted to the official Debian image running 3.14.79-odroidc2, and all was well again. As you can see below, my Teac USB is now listed (and working) charles@odroidc2:/etc$ lsusb 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 002: ID 0644:8043 TEAC Corp. Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub My main problem with 3.14 is that it pegs the CPU at 100% with a kswap thread if the machine gets close to running out of physical memory. Mostly, that doesn't happen, but when I build certain software using parallel Make, it completely locks up the machine. I notice the swapiness is set to 0 in /etc/sysctl.conf, which some people recommend to minimize the chances of the kswap process getting out of control. So, I would really like to move up to a 4.x kernel, and require very few devices to work since it will be a headless music server. Are the recent nightly builds for the C2 configured with snd-usb-audio support? If not, can they be? Charles.
  7. Hi, I'm currently considering an ODROID C2 to replace an Rpi3 as a combined headless tvheadend and mysql server, with GPIO control of a relay for a fan. It's upgrading to Gigabit LAN that I'm after, to avoid the occasional bottleneck to my NAS. Legacy sounds like it's working well enough on the C2, but the USB T2 tuners I'm using are only supported in kernel 3.19 or above... The C2 page suggests only legacy is available, but the package repository page suggests otherwise: linux-image-odroidc2 3.14.79 Amlogic S905 Hardkernel Odroid C2 linux-image-next-odroidc2 4.13.3 Amlogic S905 (meson64) Hardkernel Odroid C2 What, if anything, has been broken in the mainline release? Anybody had any experience of it here? Many Thanks,
  8. Hi all at present state , i installed slim or gdm , but they are not good to start GUI automatically . so i start GUI by startx . what display manager is good for ondroid-c2 ? cat .xinitrc startxfce4 --- regards i write the install steps at http://odroid-akita.blogspot.jp/2016/04/odoroid-c2.html (japanese input is OK)
  9. Hi - I am trying to find out from the fora topics here as well the technical details page if the ODROID-C2 has an extension to the ARMv8 instruction set to improve the speed of applications, like openssl/openvpn, performing encryption and decryption. On the intel platforms this feature is known as AES-NI. Therefore is similar hardware on board and if so, which kernel module enables this feature please? Also when will " Armbian " stretch be available ( 17 July just like debian 9? ). Cheers
  10. Has anyone had any luck cloning their repository as described on http://openlinux.amlogic.com/wiki/index.php/Arm/arm-Kernel_Info/Kernel4.9 So far it just keeps timing out on me.
  11. I am trying to follow various tutorials on full disk LUKS root encryption for Odroid C2 with a emmc. Every tutorial I have found makes use of a separate partition for boot. Something like /dev/sdx1 (vfat) 100Mb. Mostly raspi tutorials but a few others that are step by step instructions out there as well. The armbian.img file does not have a separate boot partition when I use dd to transfer to emmc or sdcard. Do I just make a vfat partition on /dev/mmcblk0 (the emmc) and copy the /boot folder over to /dev/mmcblk0p1, and run dd again to put the arbian.img on /dev/mmcblk0p2? Anybody know of a what I need to do to make that partition so I can try some tutorials and get initramfs to boot LUKS?
  12. Hello Igor, In past threads, it seems a bit argued about the zram module, but will not the zram module be enabled by default on other arm boards? I am using odroid-c2, but it is effective in hardkernel? It seems that it is becoming. If possible, if Armbian seems to have no problem, I want it to be valid. https://forum.odroid.com/viewtopic.php?f=136&t=20116 $ grep "ZRAM" /boot/config-3.14.79-odroidc2 CONFIG_ZRAM=y # CONFIG_ZRAM_LZ4_COMPRESS is not set # CONFIG_ZRAM_DEBUG is not set $ lsmod | grep zram $ cat /etc/armbian-release # PLEASE DO NOT EDIT THIS FILE BOARD=odroidc2 BOARD_NAME="Odroid C2" VERSION=5.31 LINUXFAMILY=odroidc2 BRANCH=default ARCH=arm64 IMAGE_TYPE=stable Best regards.
  13. Hello, I recently bought Odroid C2. Legacy Ubuntu Server image works great, but Ubuntu Server Next (mainline kernel) doesn't boot. SSH shows network error: connection timed out, screen is black. Is it something wrong with current image or my hardware? (Other OSes are working fine like legacy dekstop, DietPi). Power supply is official barrel DC jack 5V/2A.
  14. Hello, I am going start work with Odroid C2. In odroid C2, first need to install OS which they given in site or can i install linux based home automation software directly..?
  15. Hello. Is worth to try this branch https://github.com/moonlinux/linux/tree/odroidc2-3.14.y-rt in order to build a realtime kernel upon https://dl.armbian.com/odroidc2/Debian_jessie_default.7z ? Thanks. Managed to install this https://github.com/moonlinux/linux/tree/odroidc2-3.14.y-rt , but the latency test is pretty bad: $ sudo cyclictest -t1 -p 80 -n -i 10000 -l 10000 -N # /dev/cpu_dma_latency set to 0us policy: fifo: loadavg: 0.45 0.33 0.15 2/154 1318 T: 0 ( 1318) P:80 I:10000 C: 225 Min:1000000 Act: 5962494 Avg: 6220148 Max:15955692
  16. I can't get the ubuntu gui desktop to use the entire 2160p screen - it only uses 1/4 (1080p upper left rectangle.) The settings menu for display is locked to 1080p. I've searched and there are explanations as to how to set boot.ini to get 2160p (which works) but the ubuntu desktop won't use the full screen. What do I need to do to get a full screen GUI display? Thanks.
  17. Tested on Odroid C2 system startup from the USB stick (via script s905_autoscript, I prefer to run existing images without any modification). If add the script to the boot.ini a few lines, you can run images from a USB drive. This can be useful if there is on eMMC or on a SD card configured with the system and felt the need to run temporarily another system (without overwriting the existing SD\eMMC media). For example, for temporary checks new images, when unknown , to like this system or not, or for testing settings\software-that-be not to destroy the already set up working system. Process start automatically if the connected USB drive and it has a script that starts the system with the USB. When no USB media run regular system with SD\eMMC.
  18. When I changed some settings to my network config, my Odroid doesn't boot anymore. Even changing the settings back doesn't make it boot again. Has anyone had this happen before? I hooked up my UART and this is the result, it never proceeds with starting the kernel (see spoiler below)
  19. Before I was able to manually send CEC commands to my tv with cec-client. However I'm not sure how it works with Linux kernel CEC implementation. I know /dev/input0 is the node for CEC, I just have no idea what to do in this case. In case of cec-client, I would use the website cec-o-matic, but is there also a site like this for the kernel implementation of CEC? The reason I want this, is because I need to power on a tv with a remote using the odroid.
  20. Odroid C2 not booting Armbian 5.25 Odroid C2 Debian jessie default 3.14.79 after reboot te system never came up. red solid light. blue blinking light. Please help. uart log added:
  21. Hello, I installed Armbian on my Odroid C2 and need to run a 32-bit application. When I try to run it I get No such file or directory so I tried to install ia32-libs but can't find it for Armbian, even tried to compile the application on my Odroid C2 but it runs out of memory (tried with swap files too but it didn't work). Can someone lend me a hand please? Thanks
  22. Hello. I´ve buyed an Odrid c2 and installed armbian. Now i installed the x11vnc server and it works only when i start it manual. It start in putty with: sudo x11vnc -usepw -forever -display :0 or with the Desktop gui version. Then i can connect from my Windows PC. I installed it with these: http://www.gtkdb.de/index_36_2265.html(yes, i renamed it with my account name) but the autostart doesn´t work. Then i edit the /etc/rc.local file and wrote x11vnc -display :0 -forever -usepw -ultrafilexfer before the exit 0 command. but it doesn´t start after reboot. Can anyone help me with this please? Sorry for my bad english^^
  23. Hello All, how can I get hardware video acceleration for S905x on Debian/Armbian using Gstreamer? I installed gstreamer, and using 'decodebin' and 'fbdevsink' gives terrible performance (software decoding). I did some searching and found that amlogic has two GST plugins for hardware accelerated video decoding: "amlvdec" and "amlvsink" I was able to locate the source code here: http://openlinux.amlogic.com:8000/download/ARM/filesystem/ I downloaded the newest archive "arm-buildroot-2016-08-18-5aaca1b35f.tar.gz" Would this work with debian/Armbian? When I try to compile the plugin, I get the message: so I searched online, and found: https://github.com/mdrjr/c1_aml_libs I tried to compile this however I got the error: Does anyone know how I can get Gstreamer to play videos with hardware acceleration? Thanks so much!
  24. On the odroid c2 server I want to install jwm with xorg. What packages are needed for xorg? The log complains that it cannot find fbdev.
  25. Installed from Armbian_5.14_Odroidc2_Ubuntu_xenial_3.14.72. Tested in two different Odroid C2's. One with EMMC, the other with SD CARD and fully updated.
