Hi Chris, Is there any local changes has been made ? especially at kernel side drivers/acpi/ and driver/thermal

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.

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@60 video=LVDS-1:d video=VGA-1:e Thanks, Sreeju From: Chris Tapp [mailto:opensou...@keylevel.com] Sent: Friday, February 21, 2014 8:02 PM To: Selvaraj, Sreeju ArmughanX Subject: Re: [meta-intel] [yocto] Where's my 'thermal_zone'?
