AM6442: How to implement time sync between A and R5F?

Hello Zekun,

Are there any time sync examples?

Neither the existing SDKs (SDK 9.2 and earlier), nor the upcoming SDK 10.0 have a time sync example implemented in them. I would like us to have an example for SDK 10.1, but at this point time sync examples have not been prioritized relative to other development efforts - so it is entirely possible that the time sync examples get pushed back into an SDK for 2025 or later. If this example is critical for a particular customer, please reach out to me offline so we can discuss and re-prioritize as needed.

Any training material for customers?

For a very basic understanding of what the time sync router is and how it works, refer to https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1061474/faq-am64x-what-is-the-time-sync-router-for-how-do-i-use-it

How exactly does the customer want to use the CPTS?

Regards,

Nick

Got it, Nick.

Customer want to make sure the performance of using IPC to achieve timesync between A and R. They need R core send IPC to A core, and want to make sure the time consumption of IPC, Do we have this kind of data?

Hello Zekun,

How close does the customer need the clocks to be between the A core and the R core? Also, what OSes are running on each core?
