      Ping @Martin-Kudláček

      If I want to find out the Patron CPU serial number, is it like this?

      cat /sys/devices/soc0/serial_number
      

      ...or

      cat /sys/devices/soc0/soc_uid
      

      Second question: If this is the serial number of the CPU, is it unique to all devices?

      Thank you!

      /Vesa

        Hello @Vesa-Kauppinen,

        this has been subject to change between Linux kernel versions - the older one

        cat /sys/devices/soc0/soc_uid
        

        comes from the original iMX kernel and has been removed by NXP in newer releases. In our kernel image, we additionally preserve it for backward compatibility.

        However,

        cat /sys/devices/soc0/serial_number
        

        is a "Linux standard" provided by recent NXP kernels that we recommend using as a unique identification.
