I kept all your modifications for i2c-tools utilization.
I just removed this:

because it is not correct ($7 as $8 is correct).
I forgot to update the dependencies. Now I have added a new version and in the menu "about" I put the WARNING.

Nochmals vielen Dank!

m750,

I am sorry but you will have to put another version again.
You are correct but I am also
standard busysbox will produce output of ps likel

Code:

~ $ /bin/busybox.ori ps -ef | grep /opt/savecpu/savecpu.sh 

 1613 root      2840 S    /bin/sh /opt/savecpu/savecpu.sh start 

 3277 user      2848 S    grep /opt/savecpu/savecpu.sh

where $7 is right
but busybox-power (which I use and advise to use) produces:

Code:

~ $ /bin/busybox ps -ef | grep /opt/savecpu/savecpu.sh 

 1613 root      2840 S    {savecpu.sh} /bin/sh /opt/savecpu/savecpu.sh start

 5699 user      2848 S    grep /opt/savecpu/savecpu.sh

I will check code and put some solution, just wait a few minutes ...

Ok, took a few minutes longer, needed some dinner in bewteen.
Here is patch

When did you install? From which repo (must be testing or devel)? Just checked and latest version is not yet available. So I assume you got 17-1 which did not have the dependency, so probably you are missing i2c-tools. Check via
dpkg -l | grep i2c
and if not
sudo apt-get install i2c-tools
with testing (or devel) repo enabled.
Alles klar? Meld dich wieder...

Hi, I have installed saveCPU two hours ago. Testing and devel are active. I got 17-1. And now I got an upgrade information. After upgrading I have version 17-2. I rebooted the phone, started saveCPU again but there is still a "0". When I type "dpkg -l | grep i2c" in the terminal I get:

ii i2c-tools

.0.2-1maemo3

I2c tools for linux

Re: [Announce] saveCPU - overheating control for overclocked n900

Yes, 17-2 was latest update (which will need some correction, but only regarding UI On/Off indicator)

Please try
sudo i2cget -y 2 0x55 0x06 w
in termnal and let me know.

Re: [Announce] saveCPU - overheating control for overclocked n900

I typed:

sudo gainroot (enter)
i2cget -y 2 0x55 0x06 w (enter)

Message: "Could not set address to 0x55: Device or resource busy"

Re: [Announce] saveCPU - overheating control for overclocked n900

Oops!
Do not know what is going on.
Please do a shutdown, pull out battery for a few seconds, then boot up and try again.

Re: [Announce] saveCPU - overheating control for overclocked n900

Same result. Could meecolay-core be the reason?

Otherwise I am running a widget, which shows the temperatur on the desktop ...

Re: [Announce] saveCPU - overheating control for overclocked n900

Possibly yes.
Seems there are some libs replaced. (pls see also this http://talk.maemo.org/showthread.php?t=83939)
But I do not know.

Would love to get some confirmation of other testers.

@acurus_
Which widget, what code?
Using omap temp are useless (constand -40 or 0 or ...), bq27x00 deprecated together with BME, so i2cget is my preference to use.

Re: [Announce] saveCPU - overheating control for overclocked n900

I have installed saveCPU now on another N900 where I haven't installed meecolay-core. But saveCPU do not run as well. Therefore meecoly-core is not the reason.

I am using Desktop Command Execution Widget with this script:

echo `cat /sys/class/power_supply/bq27200-0/temp` °C | sed 's/\B[0-9]\{1\}/&,/'

EDIT: I killed this widget and rebooted the phone. But there is still the "0" for temperature ...

Re: [Announce] saveCPU - overheating control for overclocked n900

OK, confirm your problem here. Module bq27x00 is the problem.
So seems you are on KP <50?

Will investigate and think it is easy to fix that too.
So for people having bq27x00 enabled using that and for others using i2cget.

Do not know if I make it ready tonight, so could take until tomorrow.
And we have to wait for m75p to release it.

Re: [Announce] saveCPU - overheating control for overclocked n900

Sounds good! Thanks!!!!!!

I am using Power Kernel 50.
