  1. Hi, just a quick question: Why is OTG disabled? I read some "performance issues" or "high CPU usage by OTG" etc... But can someone be more specific?
  2. I have a cubieboard2 running Armbian_4.5_Cubieboard2_Debian_jessie_4.2.3.zip and when I ran a seemingly innocent "npm search" command, the system became extremely slow. It responded to pings, but SSH commands were taking many minutes to complete. I was able to grab a screenshot of "top" while it was in this state (attached). Root is on SD, I set up a 1GB swap partition over SATA. My questions are: * Is setting up a 1GB swap partition over SATA a bad idea? * Why do all of the processes suddenly report 100% CPU when main memory runs out? * How can I prevent this in the future? * Is there any other diagnostics or tests that can help determine the root cause? Thanks, Terence Haddock
  3. Hello! I use cubieaboard2, setup "trusty_3.4.110_desktop", on first boot the cubieboard2 itself off. Power Off after the kernel load labels. Debian_jessie_4.4.1 work fine. Why may power off spontaneously?
  4. I am try to activate the audio for cubieboard 2 with the OS armbian with the kernel 4.1.4 and I do not get it by the output jack. Before I install this distribution, I had a cubieez and this OS worked the audio with alsa. Is impossible have audio with this kernel? Thanks in advance!

  7. Update: checking download file, it seems that I downloaded Armbian_4.5_Cubieboard2_Debian_jessie_4.2.3.zip so it's not 4.81 no matter what the download pages said. I'm trying to install upstream kernel on Cubieboard 2 and kernel never starts. Attached is output from boot (I'm getting same on serial port). I did try different sdcard (to rule out problems with it) but I'm worried about ext4fs_devread read error and partition error. Is there something more that I can try? Legacy kernel works well, but I wasn't able to just upgrade kernel and u-boot on it, but that resulted in unbootable system -- which packages I have to install to migrate from legacy to upstream kernel?
  8. So continuing from this thread since i dont wanna threadjack im facing a simular issue using this image used rufus instead of suse imagewriter since its defunkt on windows 10, have tested the sdcard with 0 errors took about 3 hours to do so since im using a 32gb card for my server. Warning: Only 30418 of 30419 MByte tested. Test finished without errors. You can now delete the test files *.h2w or verify them again. Writing speed: 5.57 MByte/s Reading speed: 8.19 MByte/s H2testw v1.4 So same scenario as the ubuntu distro Found U-Boot script /boot/boot.scr [ bytes read info ] ## Executing script at 43100000 ** File not found /boot/.next ** ** Unrecognized filesystem type ** [ bytes read info ] ** ext4fs_devread read error - block ** Can't read partition table on 0:0 ** ** Invalid partition 1 ** Kernel image @ 0x48000000 [ 0x000000 - 0x558a0 ] Staring kernel ... as the first boot always takes some time while swap etc is being built and i left it alone came back an hour later still stuck on starting kernel. any advice at this point ?
  9. I just installed Ubuntu on A20 Cubieboard2. I have two situations. First boot stops if no ethernet connection present. Because of location issues need to use wifi by default. I need to have startx run without me having to login first and manually issue startx command. Other than this two issues all seems fine. Any help will be appreciated. Thanks.
  10. Cubieboard2 Mali400 driver is able to compile, but no fps advance\ I'm using Armbian 4.2 the compile process is based on http://blog.eldajani.net/banana-pi-arch-linux-accelerated-mali-gpu/
  11. Hello, I'm running armbian on the cubieboard 2 and have noticed something that might be an unexpected behavior: when running on NAND, the nand2 partition is mounted with ordered data mode (despite the fstab configuration)! It looks like the system tries to remount the partition in writeback data mode, but it is not allowed to, according to the following messages: root@siamserver:~# dmesg | grep EXT4 [ 12.504386] EXT4-fs (nand2): mounted filesystem with ordered data mode. Opts: (null) [ 17.557900] EXT4-fs (nand2): Cannot change data mode on remount [ 17.604119] EXT4-fs (nand2): Cannot change data mode on remount As the official cubieboard 2 download page states the writeback mode as a performance tweak and the fstab states that the /dev/nand2 partition should be mounted with writeback mode, I'm not sure if this is the default behavior or if this is happening only here. Another important thing I've noticed: if running on SD card, the partition is really running on writeback mode! And the same fstab is used (the script just changes the mmc string to nand2) As my intention is to have the system safe after unexpected power failures I'm good with this option (despite some corruptions from time to time), however I just want to make sure that everything is fine here and, most importantly, that my partition is really being mounted in ordered data mode (as obvious as it may sound) Regards
  12. Hello, How I make to use usb printer in cubie2 with Armbian 4.3 jessie? I make the POS system and now i need the enable use printer usb. Regards, Marco Aurelio
  13. Cubieboard2 How to create the armbian image with capability of booting with gps connected to the uart port ? The armbian can't start if gps connected to the uart port and vice versa - It starts with unpluged gps. After system is started up, I do connect the gps and can easily get the gps data from /dev/ttyS0 As I understand - it's happened because of ttyS0 can be using as keyboard, so bootload is interrupting. Also it's can be a problem while initial password changing.
  14. I use Armbian_4.3_wheezy on SD video with 1280x720p resolution. When I transfer to NAND, only with the resolution of 1028x1024p and can not adjust the resolution to 1280x720p. Already changed the script.bin file (via fex2bin), the uEnv.txt file (disp.screen0_output_mode = EDID: 1280x720p60) and not worked. How can I change the resolution to 1280x720p? Best Regards Marco Aurelio
  15. Hi, I'm using Cubieboard-2 Armbian_4.2_Cubieboard2_Debian_wheezy_3.4.108. The problem is that there is no Line in device, my test with arecord: I have no idea on how to activate the Line in configuration. Do I need to enable it in .fex script? Or there is no hardware support? Can anyone help me? Thanks
  16. dear All. I need CAN-BUS on my cubie2. I Found that I can reach it via PH20-PH21 Mux-4 and fortunately they are maped to extention port. So I made FEX modification like : [can_para] can_used = 1 can_tx = port:PH20<4><default><default><default> can_rx = port:PH21<4><default><default><default> Currently my board run with --> 3.4.107-cubietruck I found a banananian guy post ( http://www.lemaker.org/thread-13107-1-1.html ) a tutorial on how he make it for his BananaPI board. I tried to follow his step, but skip steps about uImage and firmware .. since I don't know how to adapt it to Armbian. when the proses complete, reboot ... I got /dev/can0 as expected but dmesg say alot of error about can4linux. I post error messages on pastebin --> http://pastebin.com/qp5Gnvj7 Kindly please give me any enlightenment to fix the problem. Sincerely -bino-
  17. I have installed Armbian on my Cubieboard 2 and Banana Pi, and a few hours ago for some reason I want to upgrade the kernel from 4.1.2 to 4.1.6 on both of them, then the story begins... I. First, below is a list of partitions on Banana Pi (same on Cubieboard 2) (notice that I attached a SATA hard drive on it, and created 2 primary partitions) ➜ ~ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 ~~~G ~~~G ~~~G 16% / (where system actually resides) /dev/sda2 ~~~G ~~~G ~~~G 81% /data (data storage) /media/mmc/boot 7.3G 813M 6.2G 12% /boot (SD card, used for booting) I installed my system on /dev/sda1 using /root/nand-sata-install To upgrade kernel, I followed the instruction on website, i.e., run the following command as root: wget -q -O - http://upgrade.armbian.com | bash After the upgrade completed, I immediately (didn't reboot) used apt-get to upgrade packages apt-get update && apt-get dist-upgrade List of installed packages # installed when I run wget -q -O - http://upgrade.armbian.com | bash 2015-09-15 17:12:24 install libboost-iostreams1.54.0:armhf <none> 1.54.0-4ubuntu3.1 2015-09-15 17:12:25 install libept1.4.12:armhf <none> 1.0.12 2015-09-15 17:12:26 install libsigc++-2.0-0c2a:armhf <none> 2.2.10-0.2ubuntu2 2015-09-15 17:12:26 install aptitude-common:all <none> 2015-09-15 17:12:28 install libcwidget3:armhf <none> 0.5.16-3.5ubuntu1 2015-09-15 17:12:29 install libxapian22:armhf <none> 1.2.16-2ubuntu1 2015-09-15 17:12:30 install aptitude:armhf <none> # installed when I run apt-get update && apt-get dist-upgrade 2015-09-15 17:46:07 install linux-image-next-sunxi:armhf <none> 4.2 2015-09-15 17:48:59 install linux-firmware-image-next-sunxi:armhf <none> 4.2 2015-09-15 17:49:00 install linux-headers-next-sunxi:armhf <none> 4.2 2015-09-15 17:49:21 install linux-u-boot-bananapi:armhf <none> 4.2 2015-09-15 17:49:36 install linux-dtb-next-sunxi:armhf <none> 4.2 2015-09-15 17:49:37 install linux-trusty-root-next-bananapi:armhf <none> 4.2 II. Then I reboot. Banana Pi goes into a infinite boot loop (Cubieboard 2 also goes into the same loop after upgrading) first, the screen shows some message: U-Boot 2015.07-dirty (Aug 25 2015 #$@%$^%) (...some text I think not related to the issue...) and the screen flashed into next screen, again with some message: Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance. (...messages...) Rebooting in 10 secconds.. then the first screen, second, first, second, first, second... After some investigation, I found that /boot/boot.cmd seems to be the culprit of the boot loop, the first line in the file gave the wrong root partition: setenv bootargs console=tty1 root=/dev/sda2 rootwait rootfstype=ext4 ...... It should be /dev/sda1, so I corrected that to /dev/sda1 and run the following command, then reboot, everything goes fine. mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr I know how to fix it, but has anyone find out the root cause of this issue? Thanks.
  18. Hi, I would like to ask you guys if you have any experience in deploying a Hadoop Cluster on cubieboard2. I am using Debian jessie 4.1.4 and I am having a lot of trouble doing it. The problem is with the ports, they are not opening when I start the hadoop daemons, so my question is: Is it even possible to deploy hadoop on Debian Jessie 4.1.4? I have tried everything. Fresh install, deploy a configured hadoop cluster that was working on ubuntu 14.04 LTS, forcing the ports to open which took me to an unsolvable error( related to Protocol Buffers ), but the main problem is the ports not opening, giving the Connection Refused error. Please share your knowledge, cause I cannot sleep untill I get it done . Thank you
  19. Hi! I am experiencing problems with sd image install into NAND.

Can someone confirm plz?
  20. I just tried out kernal 4.1.4 and whenever I try to boot (first run) I get a kernal panic just before the automatic reboot. After the reboot, the same process occurs. Tried Debian wheezy, Debian jessie and Ubuntu Trusty kernal 4.1.4, build 5.8.2015
  21. Hi After reading this: "No audio driver, IR, NAND, BT, HW video, I2C and SPI untested on 4.0 or higher​" i'm not sure which kernel version should i choose. Is that "no audio driver" means that there is no HDMI audio, or no any audio including jack audio? Both kernels support the "Allwinner Security System cryptographic accelerator"? As i'm using CB2 as a headless java application server, samba fileserver, dlna server and music player daemon server, i need only jack audio from these, and of course the hw cryptographic support.
  22. Hello Igor, I have a question, does the image has a built in NFS kernel module? I would like to use my CB2 board as an NFS server. Thanks PS.: on the site a small list about compiled kernel modules would be usefull
  23. Hi, How to build the Phoenix image from the Cubieboard2 NAND-flash? If anyone have idea I would appreciate. regards, Rassul.
  24. Hello, I used your newest Debian wheezy Image 3.8. Boot up from SD installed to NAND via script so far everything fine. But if I remove the SD card it won't boot anymore, it even doesn't show some output on serial connection. Can you give me a hint how to solve it? Thanks Fips
