how to change the APU CPU frequency of ZCU102 evaluation board

Hi,

 

I have a ZCU102 evaluation board. Currently it is running at 1.2 GHz, shown in cpuinfo_cur_freq. I like to know:

 

1) how to  know if the board can support 1.5GHz CPU frequency or not

2) If yes to 1), how to configure it to 1.5 GHz. (scaling_max_freq shows 1199880. )

 

Thanks!

Re: how to change the APU CPU frequency of ZCU102 evaluation board

My evaluation board has the part# XCZU9EG-2. It should support the max ACPU at 1333MHz. Currently it is running at 1.2GHz (shown in cpuinfo_cur_freq).

 

By checking scaling_max_freq and scaling_available_frequencies, the max frequency is 1.2GHz. Is there a way to change the max freq to 1333MHz and set the current frequency to this value?

 

Many thanks!
