  1. Hello

    i found it on both my Opi PC+ and Opi Plus 2E , Both  ARMBIAN 5.59.180918 nightly Debian GNU/Linux 9 (stretch) 4.14.70-sunxi.

     

    As i get some stability issues with Jeedom i'm playing with frequencies and governors and found that strange thing :

     

    root@orangepipcplus:~# cat /etc/default/cpufrequtils && cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    # WARNING: this file will be replaced on board support package (linux-root-...) upgrade
    ENABLE=true
    MIN_SPEED=408000
    MAX_SPEED=1296000
    GOVERNOR=ondemand
    240000 480000 648000 816000 912000 960000 1008000 1104000 1200000 1296000
    root@orangepipcplus:~#

    it seems there is a mismatch between MIN_SPEED=408000 in cpufrequtils and the one returned by scaling_available_frequencies 480000

     

    is it normal or there is an error somewhere.

    can it be an instability cause ?

     

    best regards

     

  2. yup, it isn't the way i thought at, but it works perfectly as is.

     

    well done, thanks for your hard  work on all those SBCs.

     

    EDIT // now i try to run the test with 4.17 kernel and it returns :

    /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq is unavailable :

    scaling_available_governors  scaling_driver
    scaling_max_freq  scaling_setspeed
    

    there is only scaling_cur_freq but if i undersatnd, it seem to be the value that kernel is thinking cpu is running instead of real value (in throttling case it's inaccurate).

  3. Thanks martinayotte. 

     

    The strange thing is echo works well in some case, eg :

     

    echo 1234 > test.txt

     

    Works perfectly... 

     

    I understood rtc was entirely rewritten in last kernel release. 

    I'll try your advice tomorrow thanks a lot. 

  4. Hi

     

    i'm trying to include a ds3231 rtc module but i'm facing an issue with Opi+2E nightly 5.54 and 4.17.11 kernel

     

    I2c-0 and I2c-1 activated through armbian-config : check

    i2c-tools installed : check

    module correctly wired

    i2cdetect -y 0 show me the 0x68 for DS3231 and 0x57 for EEprom

     

    but adding new_device returns :

    root@orangepiplus2e:~# echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-0/new_device
    echo: command not found
    close failed in file object destructor:
    sys.excepthook is missing
    lost sys.stderr

     

    I seen that link https://www.kernel.org/doc/Documentation/rtc.txt

    pointing on "tools/testing/selftests/timers/rtctest.c" but googling said nothing to me, i'm not skilled to do something.

    does anyone has a clue please ?

    After 7 months of work on this now let's close the chapter.

     

     

    Hi tkaiser.

     

    I just seen that topic since your last post.

    do you mean OMV support will be stopped or just you won't provide more bench as you did before ?

     

    i'm just trying a self compiled OMV build for OpiPC+ and it seem to work flawlessly !

    i'm now compiling an odroid XU4 for my friend, HC1 owner.

     

  6. Hello.

     

    I'm an happy armbian loaded Opi Plus 2E and Opi Pc Plus user and i want to thanks a lot the armbian community for their hard work on H3 devices.

    I use Plus 2E it as a seedbox/NAS with two 2.5" btrfs Raid1 1gb usb hdd, I must say that i love that little board.

     

    But, a friend of me wanted to buy one and told me that it was unavailable for now .

     

    Do you think it's temporary out of stock or we can consider it a discontinued board ?
