AM5716: Erratas for C66 core

Markus Mueller

Part Number: AM5716
Other Parts Discussed in Thread: SYSBIOS

I am using the C66 core on a AM5716 sitara processor.
Could you tell me the relevant silicon errata documents for this type of processor?
And which hardware registers do I have to read to get the revision id mentionned in those errata documents?

Regards,
Markus

Hi Markus,

The Errata document for AM5716 can be accessed from the product page: https://www.ti.com/product/AM5716

Here is the direct link to the Errata document: https://www.ti.com/lit/pdf/sprz436

Please refer to the TRM for the exact register descriptions corresponding to the Errata document:

Here is the excerpt from the TRM that contains the relevant section: https://www.ti.com/lit/ug/spruhz7j/spruhz7j.pdf?ts=1671985979996&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAM5716

Hi Karthik

Thank you for this information.

Within "packages\ti\sysbios\family\c66\cache.c " I found a hint to a bug described in SPRZ331G.
Is this relevant for the C66 core within the AM5716?

For some other features (like EventCombiner or Exception) the implementations from "packages\ti\sysbios\family\c64p\" are used.

Which is the correct cache implementation for the C66 core within AM5716?:

packages\ti\sysbios\family\c66\cache.c
or
packages\ti\sysbios\family\c64p\cache.c?

Regards,
Markus
