Hi all,

I want to measure clock frequency in secure world. I am using the function: read_cntfrq (https://github.com/OP-TEE/optee_os/blob/master/core/arch/arm/include/arm32.h#L529) to get it.

On Hikey,  The value I get is: 1.2MHz, is it scaled down or this is the actual frequency?

Thank You,

Aravind
