AM623: Clock configuration done by SDK

Koichiro Tashiro

Part Number: AM623

Tool/software:

Hi,

According to clock tree tools, all PLLs and dividers are already configured by default.
For example, below is PLL0.

My customer is asking who is configure these settings in SDK.
ROM code, System Firmware, U-boot , kernel(driver) or else?

They wants to change some clock settings from these default values.

Thanks and regards,
Koichiro Tashiro

    The ROM code will setup only the PLLs necessary to boot the device form the designated interface
    Then, depending on which software is used, either the SBL will configure the clocks, or a combination of SPL and uboot.

    All user changes to clock settings should be applied via the system firmware.
