  1. Good evening All. I was wondering what is the best method to use an Armbian sd card born for an H3 based board on another board with the same SoC, e.g. Orange Pi 2 image on Orange Pi Lite. With old 3.x kernel it was super easy, just replace the fex file and that's it. Overlays confuse me a fair bit, and the best method I found until now is to specify in armbianEnv.txt the row fdtfile=sun8i-h3-orangepi-lite.dtb to use a sdcard loaded with an Orange Pi 2 image in my Orange Pi Lite. But I cannot find where the board is defined, could anyone point me in the right direction? Best Regards. Christian
  2. Thanks! I had MAX_SPEED=1510000 instead of MAX_SPEED=1512000. Now it works!
  3. Hi, I'm using ARMBIAN 5.73 stable Ubuntu 18.04.2 LTS 4.4.174-rockchip64. It seems max clock for all cores is 1.51 GHz, however the output of cpufreq-info shows that 1.51 GHz is hardly used, despite CPU load at 100% (Plex media server transcoding), it sits for most of the time at 1.392 GHz. Am I missing something? I tried also changing governor to "Performance", but this didn't help. uname -a Linux rock64 4.4.174-rockchip64 #6 SMP Sun Feb 10 10:43:16 CET 2019 aarch64 aarch64 aarch64 GNU/Linux cat /sys/devices/system/cpu/cpu{0,1,2,3}/cpufreq/scaling_available_frequencies 408000 600000 816000 1008000 1200000 1296000 1392000 1512000 408000 600000 816000 1008000 1200000 1296000 1392000 1512000 408000 600000 816000 1008000 1200000 1296000 1392000 1512000 408000 600000 816000 1008000 1200000 1296000 1392000 1512000 cpufreq-info output: CPU has heatsink and fan, temperature stays below 55 degrees C with 100% constant load. Many thanks for your help. Regards. Christian
  4. Solved reinstalling libnss-mdns. Regards. Christian
  5. Hi. I added a second wireless interface to my Rock64 and created a wifi hotspot using armbian-config. Now .local domains are not resolved anymore. I tried changing in files /etc/resolvconf/resolv.conf.d/base and /etc/resolvconf/resolv.conf.d/head IP from to but nothing changed. avahi-resolve-host-name is ok: christian@rock64:~$ avahi-resolve-host-name orangepi2mini.local orangepi2mini.local but christian@rock64:~$ ping orangepi2mini.local ping: orangepi2mini.local: Name or service not known Could anyone point me on what could have gone wrong? Many thanks. Christian
  6. Hi all. I'm trying to figure out how to use gstreamer to encode h264 video on Rock64 (Rockchip RK3328). I'm using Armbian Bionic 5.60 (stable Ubuntu 18.04.1 LTS 4.4.156-rockchip64). I compiled mpp and gstreamer-rockchip from and installed both, but I'm still missing mpph264enc, how do I get that? gst-inspect-1.0 mpph264enc says: No such element or plugin 'mpph264enc' Many thanks for reading, any help would be greatly appreciated. Regards. Christian
  7. Did not work for me. I had already an Armbian image wrote to SD, so I patched the file /boot/boot.cmd and recompiled with sudo mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr. Then rebooted and ran nand-sata-install. This is the bootlog: I don't know if this is because I am using an hdd instead of sdd, and maybe the slow spin up time causes problems... I will try with another disk.
  8. The problem was the wifi region setting unset, this prevented to tune the radio to channel 1.
  9. Hello. Please could someone help me to solve this issue? I have a wifi dongle recognized as: Bus 002 Device 002: ID 148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter I am trying to use it on my Rock64 and ARMBIAN 5.42 testing Debian GNU/Linux 9 (stretch) 4.4.124-rk3328 uname -a: Linux rock64 4.4.124-rk3328 #24 SMP Wed Mar 28 17:15:52 CEST 2018 aarch64 GNU/Linux It seems it is recognized correctly: Using Network Manager had no luck, the device was always listed as disconnected. So I tried to configure it manually in /etc/network/interfaces, adding this entry: auto wlx441ca87f7a19 iface wlx441ca87f7a19 inet dhcp wpa-ssid mySSID wpa-psk [key removed] Still no luck, this is the log of networking service: I also tried to add: options rt2800usb nohwcrypt=y in /etc/modprobe.d/rt2800usb.conf, as I read somewhere and removed and reloaded the modules, no change Trying the scan manually I get no results: wlx441ca87f7a19 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off sudo iwlist wlx441ca87f7a19 scan wlx441ca87f7a19 No scan results I also connected the module to my laptop (running Ubuntu 17.10) to be sure it works, and from there I can connect to my wifi just fine (using Network Manager). I also can connect to wifi using another usb adapter (Realtek 8188EU USB) on Rock64 with Network Manager. Any idea? Thanks in advance.
  10. Hello, I noticed that Orange Pi 2 mini has disappeared from supported boards. Is it possible to use image for Orange Pi 2, although the "mini" does not have onboard wifi?
  11. @matteobp which build are you using? The image built on 21/11 boots correctly on my Rock64 board. Maybe you can extract some info from serial console, as explained here:

  13. Many thanks. Looking at this page I have been wondering if I can use linux-image-next-sunxi/linux-headers-next-sunxi image on a H3 device, as both legacy and dev image are specific for H3 (sun8i). Is this possible? BR Christian
  14. Recording device can be selected using -D option. arecord -i -D hw:audiocodec,0 -f S16 -r 22050 test.wav
  15. Hello. I failed to switch from legacy to mainline kernel on my OPi 2 mini (it's an OPi 2 without onboard wifi). I installed the packages: linux-image-dev-sun8i linux-headers-dev-sun8i linux-firmware-image-dev-sun8i and rebooted, but the system hangs at "Uncompressing Linux... done, booting the kernel." (from serial console), green led solid on and ethernet port leds both solid on, no output on HDMI. Then I found this thread and tried to set the clock, but boot fails the same. Now i deleted /boot/.next and relinked zImage to the old kernel, the system booted fine. Please, someone could tell me if I have done something wrong? Many thanks. Christian
