PROCESSOR-SDK-AM64X: board config: power management how to config

Part Number: PROCESSOR-SDK-AM64X
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi,

I know we can config power management during SBL run. 

1. 

but how about the power config file?

However this file is no any power management config.  Please take a look

source\drivers\sciclient\sciclient_default_boardcfg\am64x\sciclient_defaultBoardcfg_pm.c  


2. furthermore, if we are using sysconfig,  sciclient_defaultBoardcfg_pm.c is not generated. 

I mean 
gmake -s -f .\makefile_board configure SOC=am64x
gmake -s -f .\makefile_board configure-gen SOC=am64x

power managerment is not over there




3. is that saying ti did not recommend power management setting  config during RBL.   Please do it in SBL? 



Thanks.

    hi, swargam:

    It is not why question., it is more about capability.  Can I do  PM in RBL?

    if it is capable of doing it in RBL, can you provide me an example.  eg:  sciclient_defaultBoardcfg_pm.c


    Currently, your sample code, is only config this pm in SBL, not in rbl. 


    I don't want to change the PM config. I just want to do it in RBL.   and remove from SBL. 

    Thanks.

    Hello Jun,

    The boot flow sequence is RBL → SBL → Application.

    RBL runs on the ROM memory and can't be modified by the user.

    Users should modify the SBL and Application code only.

    furthermore, if we are using sysconfig,  sciclient_defaultBoardcfg_pm.c is not generated. 

    In the SBL, we just control the rm and pm cfg all domains can access or not and this control only is doing.

    The above attached image power configurations belong to Hw and there is no control in software.

    Regards,

    Anil.
