AM2432: how to configure core clock

Moonil Heo

Part Number: AM2432

Hi Expert,

Could you let me know how to configure the core clock? From the data sheet, I can see AM2432 supports 800Mhz for R5F and 400Mhz for M4F. I found "gCoreBootInfo" in bootloader_soc.c which seems the one I have to touch. Is this array the correct point? OR Is there another way to change the clock per core?

Regards,

Moonil

    Hi Moonil,

    Yes, this array is correct point for changing the clock frequencies when using SBL (bootloader) flow. If you are using GEL files (in CCS) instead of bootloader to initialize the SOC, you need to run Set_Main_Pulsar_PLL_400MHz_400MHz() function (part of C:\ti\ccs1110\ccs\ccs_base\emulation\gel\AM24x\AM24_PLL\AM24_PLL_non_UC_configurations.gel file).

    Regards,
