Control CLK module initialization by customer's software

Hi, Champs,

When my customer wants to use BIOS5 on C6472, they have the following questions about CLK module initialization.

How to configure CLK and PRD of BIOS by customer’s software at runtime instead of using TCF file statically? The reason for this question is they have a requirement that all core will share one system timer. In TCF file, we can configure a global timer for this. If global timer was used, which core should take the responsibility to initialize it? And if the core crashed and was booted again, the timer will be re-initialized and may cause some problems. If customer can control the initialization of CLK module, they can decided to initialize the timer or not when re-boot that failed core.

Any suggestions for this are deeply appreciated.

    Tommy,

    In the BIOS tcf f you right-click on the CLK - Clock manager and select Properties you can define which core will initialize the timer.

    Even still I will still move your question to the BIOS forum so you may get additional help if you need, ok?

    Hope this helps,

    Rafael

    Rafael,

    Yes, you are right. That can configure which core to initialize the timer.

    Do you have any idea about the second question? Can we avoid the re-initialize the timer by this core when the core was re-boot because of errors?

    Please go ahead to move it to BIOS forum.

    Thank you very much.
