  1. Today I checked the legacy kernel with a known good Sandisk Ultra Class 10 card, but legacy seems to be hotter (dont know why): Linux orangepizero 3.4.113-sun8i #18 SMP PREEMPT Thu Jun 15 02:16:06 CEST 2017 armv7l armv7l armv7l GNU/Linux using ethernet (not wifi) x 00:33:29: 240MHz 0.08 4% 1% 2% 0% 0% 0% 71° x x 00:33:35: 240MHz 0.07 4% 1% 2% 0% 0% 0% 70° x x 00:33:40: 240MHz 0.07 4% 1% 2% 0% 0% 0% 71° x x 00:33:45: 240MHz 0.06 4% 1% 2% 0% 0% 0% 70° x x 00:33:50: 240MHz 0.06 4% 1% 2% 0% 0% 0% 71° x x 00:33:55: 240MHz 0.05 4% 1% 2% 0% 0% 0% 70° x x 00:34:01: 240MHz 0.05 4% 1% 2% 0% 0% 0% 71° x x 00:34:06: 240MHz 0.04 4% 1% 2% 0% 0% 0% 70° x x 00:34:11: 240MHz 0.04 4% 1% 2% 0% 0% 0% 70° x x 00:34:16: 240MHz 0.04 4% 1% 2% 0% 0% 0% 71° x x Time CPU load %cpu %sys %usr %nice %io %irq CPU x x 00:34:22: 240MHz 0.03 4% 1% 2% 0% 0% 0% 71° x x 00:34:27: 648MHz 0.03 4% 1% 2% 0% 0% 0% 71° x root@orangepizero:~# cat /sys/devices/virtual/thermal/thermal_zone0/temp 70 root@orangepizero:~# cat /sys/devices/virtual/thermal/thermal_zone1/temp 70 and with a small metal cooler stand under the OPi Zero: root@orangepizero:~# cat /sys/devices/virtual/thermal/thermal_zone0/temp 65 root@orangepizero:~# cat /sys/devices/virtual/thermal/thermal_zone1/temp 65
  2. 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! =================================================================================================================
  3. 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: http://www.ebay.co.uk/itm/3-in-1-Orange-Pi-Zero-512MB-Development-Board-Expansion-Board-Black-Case-Kit/142329429602
  4. 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.htmlOriginal 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: root@OrangePI:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: audiocodec [audiocodec], device 0: SUNXI-CODEC sndcodec-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: sndhdmi [sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 see also
  5. 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.
  6. 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.
