    Hello,

    I'm the happy owner of a Udoo QUAD system. I'm experimenting with the Debian Wheezy armHF distro.
    I'd like to know if there is a way to check the temperature (Celsius) of the Freescale processor? I don't see anything in the /proc/cpuinfo file for example:

    Code:
    debian@udoo:~$ cat /proc/cpuinfo
    Processor	: ARMv7 Processor rev 10 (v7l)
    processor	: 0
    BogoMIPS	: 1988.28
    
    processor	: 1
    BogoMIPS	: 1988.28
    
    processor	: 2
    BogoMIPS	: 1988.28
    
    processor	: 3
    BogoMIPS	: 1988.28
    
    Features	: swp half thumb fastmult vfp edsp neon vfpv3 
    CPU implementer	: 0x41
    CPU architecture: 7
    CPU variant	: 0x2
    CPU part	: 0xc09
    CPU revision	: 10
    
    Hardware	: SECO i.Mx6 UDOO Board
    Revision	: 63012
    Serial		: 0000000000000000
    Any pointers would be appreciated.

    Cheers,

    Slim

    Hi, this will give you the temperature if the kernel has it enabled:

    Code:
    cat /sys/devices/virtual/thermal/thermal_zone0/temp

    Perfect! That's exactly what I was looking for.

    Is there an upper envelope to the temperature. My system has no fan (at this point), and I've run computationally intensive tasks - and I'm seeing 65-67C - which seems on the upper end of the spectrum.

    All the best,

    Slim
