[Solved] TC3.8_4 Real Time Upgrade

[MTCAT]

Hi Rich,

See line 72 in the attached file, I was working from (scattered) memory after looking through about 50 sub-programs on Sunday, sorry that I didn't get the command exactly right, I was just "talking out loud" so to speak, sorry for the confusion.

Hi Rich,

And excited to have got the GUI to come up, just wanted to tell you about it I guess.

Thanks,

David

Hi MTCAT
That program requires you to install  lm_sensors.tcz.
Be sure to read the  info  file:
http://repo.tinycorelinux.net/3.x/tcz/lm_sensors.tcz.info

Hi Rich,

Thanks a lot for all the help, you've been far beyond amazing, I'll give that package a try later this week.

Thanks again,

David

Hi Rich,

I installed lm_sensors.tcz and then ran "sudo sensors-detect", unfortunately I didn't detect any sensors at all.

Thanks,

David

Hi Rich,

I also looked in /sys/class/thermal and this directory is empty ?

Thanks,

David

[Rich]

Hi MTCAT
So there was no file called  /etc/sysconfig/lm_sensors ?

[MTCAT]

Hi Rich,

That's correct, there was no file "lm_sensors" in /etc/sysconfig, no sensors were detected so I guess it writes out nothing at all ? I did verify that on my old non-RT kernel, I am able to cat /sys/class/thermal/thermal_zone0/temp, but it always returns 66000 (66C), not sure it's really working, and cat /sys/class/thermal/thermal_zone0/type returns acpitz. Hopefully that helps or gives you a clue.

Thanks,

David

Hi MTCAT

... I did verify that on my old non-RT kernel, I am able to cat /sys/class/thermal/thermal_zone0/temp, but it always returns 66000 (66C), not sure it's really working ...

Was that after running  sudo sensors-detect  and loading any kernel modules listed in  /etc/sysconfig/lm_sensors ?

[MTCAT]

Hi Rich,

No, on the original non-RT build, there are three symbolic links inside /sys/class/thermal, one of them being thermal_zone0, there's also a thermal_device0 (I think) and a thermal_device1, but, these have always just been there on the non-RT build, we didn't have to do anything special to get them in there (that I can recall).

Thanks,

David

Hi MTCAT
I've lost track. Are you running the pre-built RT kernel found here:
http://repo.tinycorelinux.net/3.x/contrib/rt-kernel/

If so, are the dependencies for lm_sensors loaded, including:
hwmon-2.6.33.3-l1-rt19.tcz

[MTCAT]

Hi Rich,

That's correct, I installed lm_sensors.tcz on the pre-built RT kernel. I installed lm_sensors.tcz from the app tool, so I hope all the dependencies are installed ? I'm not sure how to check that, but I did try to install hwmon-2.6.33.3-l1-rt19.tcz (after already installing lm_sensors.tcz) and I get returned, "hwmon-2.6.33.3-l1-rt19.tcz already installed !" So at least that is there, but the only thing added to onboot.lst is lm_sensors.tcz

Thanks,

David

Hi MTCAT
In th at case it is loaded. Run:

Code: [Select]

sudo sensors-detect
dmesg > dmesg.txt
Attach  dmesg.txt  to your next post. I'll be back in a couple of hours.

[MTCAT]

Hi Rich,

Thanks a lot for the help, here's the dmesg.txt file. The only thing that "sudo sensors-detect" seems to do is load module i2c-dev, which is shown in the last line of the dmesg file I think, after running "sudo sensors-detect", lsmod shows two new entries, "i2c_dev" and an "i2c_core". I also attached the output of "sudo sensors-detect" here.

Thanks,

David

Hi MTCAT
I'm not seeing anything helpful.

... I did verify that on my old non-RT kernel, I am able to cat /sys/class/thermal/thermal_zone0/temp ...

Were there any extra kernel modules loaded there that don't show up under the RT kernel?
Were you using any extra boot codes there that you are not using under the RT kernel?
