Part Number: AM6548

Hi

We had searched the content of "proc/cpuinfo", it had no CPU frequency information.

and the folder of "sys/devices/system/cpu/cpufreq", it's empty.

where can we find the message of CPU frequency with am6548 in the system?

Thanks

Kenn

    Hi Kenn,

    cpufreq is not supported on AM6548. But please use the following command to get the CPU frequency:

    # k3conf --cpuinfo
