    orange pi zero, no sound, and no sound card

    in Orange Pi Zero

    Posted

    If you decide to use the expermental MAINLINE kernel 4.x , then its possible that it hasnt sound-drivers :(

    If you want to use sound by now please use the Server-Image with the legacy Kernel 3.x

     

    On my Opi Zero with legacy kernel audio is useable and alsa-base and alsa-utils (incl. alsamixer) is installed:

    Are you able to somehow precisely measure consumption of the board (without the shield if possible)?

    I would be really interested in idle consumption and temp when telling the CPU to clock at either 240 MHz or 1200 MHz.

    No - sorry I didnt got the right tools here for that :(

    BTW: Its nice here to have 5 different boards with blinking heartbeat  :)

    Today I did get my NanoPi Duo Starter-Kit. Now it is assembled and running
    with  OS nanopi-duo_ubuntu-core-xenial_4.11.2_20170908.img.zip

    So Kernel 4.11.2 - Linux NanoPiDuo 4.11.2 #1 SMP Mon Jul 10 11:06:36 CST 2017 armv7l armv7l armv7l GNU/Linux

     

    Is that because of

    FriendlyELEC learned from a conversation with open source community that with mainline kernel they could make use of DVFS (dynamic voltage frequency scaling), something that still seems not possible with Allwinner's BSP. As a consequenze they dropped Allwinner's software offerings, rely on mainline u-boot/kernel now, have DVFS working and even re-designed a few H5 boards to implement better voltage regulation (eg NanoPi M1 Plus 2, NEO Plus2 or the new NEO Core2 which are both equipped with an I2C accessible voltage regulator).

    Does the NanoPi use DVFS?

    It doesnt get as hot as the OrangePi Zero 1.4.

    Here 50 Degree Celsius at the Starter-Kit-Case.

    New OPi Zero - Yet another high temperature issue...

    Today I checked the legacy kernel with a known good Sandisk Ultra Class 10 card, but legacy seems to be hotter (dont know why):

    Judging by the scientific method and using an external temperature meter? We invested hundreds of hours into optimising those things (check h3consumtion tool for going deeper with this), while board maker hasn't done anything at all. I am wondering how this is possible since so far we could only find people saying it's running cooler with Armbian than with stock image. There are some troubles with Zero rev. 1.4 and in general this board heat dispersion is bad.

     

    Mainline kernel is not ready yet but close. There is no way to speed up the process if you rely on few amateurs doing this.

     

    Its was a finger-feeling and not a external temperature meter, but I think I found "my problem".

    First after yor message I did use the internal temperature meter named

    cat /sys/devices/virtual/thermal/thermal_zone0/temp
    cat /sys/devices/virtual/thermal/thermal_zone1/temp (not available at Mainline Kernel)

     

    So I did try Stock-, Legacy- and Mainline-Kernel:

     

    Stock Kernel
    Linux OrangePI 3.4.39 #2 SMP PREEMPT Mon Nov 21 16:23:11 CST 2016 armv7l GNU/Linux
    idle 66-67 degree Celsius
    SanDisk Ultra SDHC 16GB Class 10

     

    Legacy Kernel
    Linux orangepizero 3.4.113-sun8i #18 SMP PREEMPT Thu Jun 15 02:16:06 CEST 2017 armv7l armv7l armv7l GNU/Linux
    idle 62-67 degree Celsius
    Kingston SDHC 8GB Class 4

     

    Mainline Kernel
    Linux orangepizero 4.11.12-sun8i #1 SMP Wed Aug 23 15:21:32 CEST 2017 armv7l armv7l armv7l GNU/Linux
    idle 54-58 degree Celsius
    SanDisk Ultra SDHC 16GB Class 10

     

    As I didnt got a third "SanDisk Ultra SDHC 16GB Class 10" I used a "Kingston SDHC 8GB Class 4" for the Legacy-Kernel.

     

    Above we can see that there isnt much difference between Stock and Legacy-Kernel here (in the end 67 degree idle), BUT

    I must admit that the OPi Zero is getting hotter around the Class 4 Kingston Card against the Class 10 SanDisk Ultra.

    So my finger-feeling could belong to a hotter MicroSD-Cards rather than to the complete system which is measured from the internal temperature-sensor.

    I have to check if the Legacy-Kernel would be running cooler if I flash it on the Class 10 Sandisk Ultra.

    Do you got informations about different temperatures with different MicroSD Cards?
    I did got this as a problem on my mind.

     

    ===============================================================================================================

    Iam very pleased with the work from the armbian-teams - also for the OPi Zero.

    I understand to esteem the hard work here while not getting informations from the maker-companys of the boards.

    For me you are all very cool doing support for single-board-computers which have lost their manufacturer-support sometimes after an initial release.

     

    I know the v1.4 doenst seems the best revision of the board in meaning of heat - but I does come with the kit to me :(

     

    If there is the legacy working for me (with a newer MicroSD Card) then there is no problem for me to wait for a great mainline-kernel.
    And if there will be audio included I will be very happy.

     

    The "few amateurs" be certain to do a great job!

    As all of our images in download section with a label "legacy kernel" which contains kernel 3.4.113 with 100+ fixes on top of horribly outdated 3.4.39, found in stock builds. There is another DEV kernel (currently 4.13), which we are talking about here and that one lacks some basic functions. 

    It is possible that certain features are disabled in board config in our image for Opi Zero. If there is no audio connector on board, this feature might be disabled ... but it can be simple enable back.

    Its fine to read that the kernel 3.4.114 has so much fixes, but with my OPi Zero and the USB/Audio-Expansionboard (plus case) - for me - its getting hotter than the stock kernel 3.4.39.

     

    The new kernel from the mainline does not getting so hot like the legacy kernel with fixes.

     

    So I will hope & bid for 2 things / possibilities:
    1.) include the dynamic cpu-switching like in mainline to the legacy kernel

    or

    2.) include/enable the audio-feature (like in the stock kernel) to the mainline kernel.

     

    I think in future much more people will request this feature (for the mainline kernel) , because on eBay they sell the OPi Zero + USB/Audio-Board + Case as a kit:

    Thank you for your fast response! Unfortunately I have ingnored that red sign... Maybe I will try other kernel if I will be in trouble with the driver.

    Thanks again!


    I did try a "official" image from http://www.orangepi.org/downloadresources/ :
    Raspbian Server - updated: 2017-05-05 
    which links to http://www.orangepi.org/downloadresources/orangepizero/2017-05-05/orangepizero_e7c74a532b47c34968b5098.html
    Original release date was 2016-11-24 with version 0.8.0 ( Raspbian_server_For_zero_H2+_V0_1 )

    Its has (as told to me) a "horrible outdated  kernel(    uname -r : 3.4.39)", but has a working audio-driver for the analog and the (not inclueded) HDMI-Connector:

    Just tested your 'official image'. Kernel is horrible outdated (uname -r : 3.4.39)

    Temps are around 67-64°C idle (armbian idle: 58-60°C)

    when you say armbian - do you use the unstable mainline version or the stable legacy?

    mainline has - as I read - no wifi-support for the onboard chip. any other drawback?

    as I use ethernet no-wifi wouldnt be a problem.

     

    [EDIT] I installed the mainline to another MicroSD Card, but as written in the follwing thread

     

    there is no audio-driver available, because normally the OPi Zero has no audio-expansion board :(
    So I will try mainline later again - and will now use the horrible outdated kernel, because I want audio-support.

    This is reply I got from Shenzhen Xunlong Software CO.,Limited aliexpress store 

    
It is normal at 45-80degrees. Cause the Zero is a tiny baord.
And we have set the dynamic frequency configuration on our offical images. This can help decrease the temp.
It will be lower under linux image than the Android image.

     

    Today I did get my Orange Pi Zero (V1.4?) with Audio/USB-PCB and case.
    My first try was armbian  with legacy kernel ( https://dl.armbian.com/orangepizero/Ubuntu_xenial_default.7z ) but the OPi Zero keeps getting very warm.
    So I did try a "official" image from http://www.orangepi.org/downloadresources/ :
    Raspbian Server - updated: 2017-05-05 
    which links to http://www.orangepi.org/downloadresources/orangepizero/2017-05-05/orangepizero_e7c74a532b47c34968b5098.html
    Original release date was 2016-11-24 with version 0.8.0 ( Raspbian_server_For_zero_H2+_V0_1 )

     

    Measured with my fingers the OPi Zero runs cooler at they stated for "official Images".

     

    Does the mainline kernel include these dynamic frequency configuration? (legacy doesnt seems to or not for v1.4?)
    I used the legacy kernel version because of the label stable.
