Hi Vineet,

I dont think it is related to SDK version. Do you have any concerns on SDK version?

Let's say current latest version for this discussion.

Thanks & Best Regards!

ZM,

Many interrupt related configurations & SMP related configurations happen on ATF.
In fact Linux some runtime commands do access ATF. Any particular reason why you
want to avoid ATF? What is the use case?

Hi Keerthy,

I found this thread. I guess it should be the same.

The reason customer don't want ATF is that, they want to ensure every component is compliant to ASPICE & ASIL.

If ATF cannot be removed, I need to ask them to prepare.

Thanks & Best Regards!

ZM,

Yes. It is not recommended to bypass ATF for the reasons mentioned in the thread you found.

Best Regards,
