    There is no thermal control for H5 yet, so you really should know what you are doing. If you do - than you'll figure out how to change DVFS

    Hi lomady, I'm a newbie on this subject. I would be interested bringing the core freq to 1GHz or more. Could you explain how to do it? An example of how to handle DVFS?

    Thanks

  2. Hi to everyone,

    I'm using "Armbian_5.38_Orangepizeroplus_Debian_stretch_next_4.14.14" on a Orange Pi Zero Plus H5

    I'd like to test this new board by working with processor overclocking. But it seems to me that it is leased at 816Mhz maximum.

    Can someone tell me how to take it to 1200Mhz or more?

    Thanks

    Antonio

  3. Hi gnash

     

    I read that in the first 1 or 2 minutes after the boot is very difficult to set the number of processors and frequency. Then in /etc/rc.local call a script and let the sleep for 2min after start the commands. It seems to work. Thanks

    If someone has a more elegant way to solve the problem is .... welcome !!

    #!/bin/bash
    sleep 120
    echo 0 > /sys/devices/system/cpu/cpu3/online  #disable CPU3
    echo 0 > /sys/devices/system/cpu/cpu2/online  #disable CPU2
    echo 480000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq  #set max frequency at 480MHz
    exit 0
    

    Now after the reboot I have 65°c. My CPU has a heat sink compatible raspberry.

    In attached file You can see, immediately after booting I stress CPU with "stress -c 4". After 2 minutes start the script that set max 2CPU e max 480Mhz.

  4. Thanks for your fast reply.
    I can wait for the neo NanoPI. However I am using the most stable versions also on a OrangePI one. I need a stable version on NanoPI neo.
    I take this opportunity to also make a note of this problem:

    root@nanopineo:/sys/class/leds# ls
    orangepi:green:pwr  orangepi:red:status
    
    

    On NanoPi NEO on /sys/class/leds there is' something of orange and NanoPI Neo has green and blue leds. Don't worry great job !!

    Thanks

  5. Hi I'm newbie

     

    Congratulations for ARMBIAN. Then ... I have a NanoPI NEO 512mb, and I have installed on uSD a image of "Armbian_5.17_Nanopineo_Debian_jessie_4.6.7"

     

    OK, after the boot I insert a wifi-dongle RTL8192cu, but i don't see nothing ..

    root@nanopineo:~# lsusb
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    
    

    What I'm wrong?

    Thanks
