Running H3 boards with minimal consumption


Recommended Posts

If DRAM clockspeed influences your application or not I don't know -- maybe you don't know too since you never tested it? In case it has a benchmark mode, adjust DRAM clockspeed and re-test 

 

That's a good point.  I suspected it did, but wasn't sure.  I tested it as you suggested and indeed it does-- the engine does have a benchmark mode.

 

The h3consumption utility seems to work well.  I disabled hdmi, usb, and reduced cores to 2, all without issue.  I can't measure actual consumption though.  The only indicator is I can look at the trends in armbianmonitor to see if there's improvement.

 

Also, I got an error when trying to lower DRAM settings.  It seemed to work, as evidenced by the speed reduction on the benchmark test, however there was no /etc/armbian-release, spitting out an error.  It seems I'm still running 5.11.  heh.  I'm not anxious to update, but the next release I will make myself do it, since I suspect the one I'm running has that awful allwinner root exploit.  Actually... I guess waiting doesn't really matter since after 5.15? apt-get upgrade is all one needs to do.  My issue is using a fresh image, but no way around that.  It's just I have it working nicely already.

Hello,

Sorry if my question is inopportune - would be possible to change all that appropriate parameters on-line, when system is working?

I mean my Orange Pi is working on very low gears, waiting for a signal (from smartphone via WiFi or BT). When the signal comes, Orange Pi switch gear up and performs important tasks (that need more power). Then a signal again and lower gear :-)

Could be very good way to make boards smarter :-)

Hi all.

Is there anyone who is running OrangePi 2 plus with mainline kernel? (mine is 4.14.18 as of now)

 

I would like to disable hdmi and other useless devices because I'm running a headless server, but my kernel supports only Device Tree overlays.

Is there any way to reduce power consumption for me?

 

Thanks

Hello,

I am looking for something like h3consumption, like marcello7, which would work with mainline kernel (4.14.37) for my Orange Pi Zero. In fact, I would just need to switch off Ethernet and disable GPU/HDMI to have a less idle consumption.

Has anyone done it and can explain me how to do?

 

Thank you :)

Mainline...currently 4.19


Features for optimising consumption are not developed in a modern kernel which means there is no luxury of just enabling/disabling. HDMI might be possible to disable in DT, but I doubt there will be any gain in lowering consumption. Since things are not explored, its difficult to be sure. You will need to invest some time to find that out.
