Hi,
How to set CPU frequency on u-boot?
Our machine must keep working at 800Mhz.But I see the frequency under U-boot is 396Mhz.
U-boot version : 2016.03
SOC:IMX6ULL
Thanks!
you can find the cpu frequency settings in the dtsi file as below:
"https://source.codeaurora.org/external/imx/uboot-imx/tree/arch/arm/dts/imx6ull.dtsi?h=imx_v2019.04_4..."
How to change the default frequency in the dts file? If I set it in the uboot, does it persist when kernel boots up? Or kernel overwrite the value?
