Hi Team,

I would like to know is there any way to read CPU freq and CPU temp from Linux (version 5.4)??
I have checked at "/sys/devices/system/cpu/cpu0/" but i wasnt seen any files or folder for cpufreq. same way tried to check /sys/class/thermal/ folder. But i didnt see any. Anyone knows any idea about this?

Access the Microchip App Note AN_44036, titled "SAMA5D23 and SAMA5D28 Environmental Monitors" from your local Microchip sales office.
