Hi there,

 

I am new to OrangePi and Linux as well and that's probably why I have faced my first problem I could not find an answer on web. I use OP Lite with the latest debian jessie.

And there is the problem (or just a bug):

after some time of using WiFi (and wwan) I wanted to disable it in order to reduce "excessive" power consumption. So firstly I had disabled it via "nmcli" and after a while I found out about "h3consumption" command. But recently I wanted to install (and download) but none of the above commands were able to re-enable them.

Any ideas how to re-enable (besides loading new OS image) ?

 

In addition, I noted that changind  "h3consumption" is not able to change dram clockspeed.

In addition, I noted that changind  "h3consumption" is not able to change dram clockspeed.

 

Well, every time I use h3consumption it tells me this after changes:

Settings changed. Please reboot for changes to take effect
and verify settings after the reboot using "h3consumption -p"

So changes need a reboot since it's either modification of script.bin (read by u-boot) or /etc/rc.local (executed at booting by kernel). In the latter file you also find the command to adjust DRAM clockspeed you now you know where to look for if you want to adjust this at runtime.

thanks for reply.

I did reboot as well as shutdown, repeated many times, none did help.

 

AS a proof, the command successfuly changed cpu speed and disabled HDMI.
