Hi,

I have QorIQ-sdk-V2.0-20160527-yocto and I can build Image for t1042d4rdb machine

I want to get cpu temperature and monitor it in my application, but I cant find the temperature in its linux!

 

I have QorIQ-sdk document too, in it said that I must check this parameter in kernel :

<*> CPU frequency scaling driver for NXP QorIQ SoCs

 

but I couldnt find it ! there is :

<*> CPU frequency scaling driver for Freescale QorIQ SoCs

in menuconfig.

there is a Device Tree Binding section in document too, what I must do with IT ?

 

 

Im new in Embedded Linux developing, can you help me to how I can access to cpu temperature ??

I want a simple road map to do

 

sorry for poor English.

thank you!
