Tool/software: Linux
Hello,
I am using BBB board. I have configured DRAM to 128 MiB Now I want to change the frequency of BBB
my uboot version : u-boot v2017.1 , Linux kernel version : 4.9.0-linux-yocto on ubuntu 16.04
- I want to make it running on 700 MHz, so I have change the "am335x-boneblack.dts" file as below,
clk_mcasp0_fixed: clk_mcasp0_fixed {
#clock-cells = <0>;
compatible = "fixed-clock";
/ * clock-frequency = <24576000>; */
clock-frequency = <7000000>;
};
But I do not think it has change the frequency,
- how can I make the CPU run on single core also?
- how can I change CPU frequency ?
To view the frequency and other information I have added command cpufreq-info, into the file-system but it gives below error.
"analyzing CPU 0 no or unknown cpufreq driver is active on this CPU"
thanks,
Amit
