Hi Chris,
Micro code revision on my bios is 10d which is higher than what you have.
For Enabling Thermal zone, it need support in both BIOS level and kernel level, and we have confirmed it is enabled in the provided kernel configuration,
and can see the thermal zone in intel CRB. So what I am seeing is he different boards in both sides along with that BIOS can also contributes to this issue.
You can check with the hardware vendor for any BIOS update. Can you upgrade the BIOS and see the issue still there.
Note: Please keep the cc list always while reply.
Thanks,
-Sreeju

Hi Chris,
I just want to clarify the Silicon stepping on your target.
To see this, you can go to BIOS main menu, then under "platform Information" check against "CDV version"
The BIOS doesn't have that menu item, but I've been able to find something which reports:
Microcode update 30661/10C.

Hi Chris,
Can you upgrade the BIOS on Intel board DN2800MT to the latest version and check
Unfortunately not, as this board is no longer available and I don't have any here.
As I said, I tested with the Intel board to see if the problem was the same as with the ASRock board that we are now using (and which is a direct replacement for the one Intel dropped last year).
You can get the latest BIOS from here:

Hi Chris,
I would like to know the BIOS detail of Intel DN2800MT, where you have reproduced the issue.
BIOS Vendor

All that I can get from the BIOS screens on the Intel board is:

Hi Chris,
You can press F2 or Delete button at start of system booting to enter in to BIOS menu.

Hi Chris,
Is there any local changes has been made ?
especially at kernel side drivers/acpi/ and driver/thermal
I do have a /bbappend for the kernel. This adds one .cfg fragment which contains:
CONFIG_HID_APPLE=y
to enable support for Apple USB keyboards.
That is the only change.
Thanks,
Sreeju

I have thermal related configuration at
Advance tab:
CPU Configuration->
TM1->Enabled
TM2->Enabled
DTS->Enabled
And "Thermal Configuration" under "Advance" tab
But changing of these configuration(Disabling) doesn't create any difference for me.
I've also tried booting on an Intel DN2800MT. That also has no thermal zone showing, so it looks as if the BIOS isn't the issue.
Another thing is command line argument "thermal.off", by default it is 0
if you are not passing thermal.off=1 as command line argument, then it is ok.
I'm not passing this, so we should be ok.

I checked the kernel configuration, fine with respect to enabling thermal zone.
And verified, after built with the config you have provided.
Can I get some info:
Once boot up the image, can you run the below commands and provide the output.
# dmesg | grep Thermal
# dmesg | grep thermal
These both report nothing.
# dmesg | cooling
This gives:
acpi device:1f: registered as cooling_device4
What is the BIOS version on your target ?
The board is an ASRock DN2800MT (the Intel board is no longer available) and has an AMI BIOS, version 1.20.
Does something need to be enabled in the BIOS for the thermal zone to appear? ASRock have been happy to make simple configuration changes to the BIOS for me in the past if this is needed.
The BIOS has a few ACPI settings, but nothing related to thermal. I suspect other settings exist, but they are not exposed to the user.
And want to check syslinux.cfg on your target.
The board is being network booted over iPXE, so there is no syslinux.cfg. The boot simply uses the kernel, initramfs and rootfs images produced by Yocto. The kernel command line is:
root=/dev/ram0 script=runme mac=bc:5f:f4:d6:eb:66 ip=192.168.1.58 dhcp netmask=255.255.255.0 gateway=192.168.1.1 dns=192.168.1.1 serverurl=http://sjs-server<http://sjs-server/> console=ttyS0,115200 quiet video=1280x1024-32 at 60 video=LVDS-1:d video=VGA-1:e

Once boot up the image, I can see the "thermal_zone0" entry under /sys/class/thermal/
I only have sym-links for cooling_device0 to cooling_device4 showing there.
I just wanted to clarify your config, What configuration is used to build the kernel ? you can find .config file inside the folder
tmp/work/cedartrail-poky-linux/linux-yocto-3.0.32+git1+bf5ee494...../linux-cedartrail-standard-build/
I've attached the config file used for the build.
