Part Number: AM3352
Hello,
I'd like to confirm which CPU frequency is selected on AM3352's Linux kernel. (I'm using SDK8.2.)
But I can't find any method or command to display CPU frequency.
On my Linux, "/proc/cpuinfo" and "dmesg" are not include CPU frequency information, and there are no CPU frequency information under "/sys/devices/system/cpu/cpufreq/" and "/sys/devices/system/cpu/cpu0/".
The attached is the result of print these files/directories.
Could you teach me how to display CPU frequency?
