Hi,
I am using AM5728 EVM. I am attempting to change MCLK by changing DTS file(s).
I measured the MCLK of its audiocodec by probing CLKOUT2 pin on SOC using oscilloscope. It gives value 22.597 MHz. I changed the clock-frequency from 22579200 to 12288000 in
dra7xx-clocks.dtsi file as follows:-
sys_clkin2: sys_clkin2 {
#clock-cells = <0>;
compatible = "fixed-clock";
//clock-frequency = <22579200>;
clock-frequency = <12288000>;
};
After compiling and copying the compiled DTBs and zImage, I booted the EVM and measured the MCLK again. It still gives 22.597 MHz.
Am I doing anything wrong? Is there any other way to modify the MCLK than only by changing the DTS file?
