Hello,
Thanks for the initial feedback , my concern is that may be some ports might be only accessed by R5F of the extended MCU , and the others might be accessed by A72.
The background of the concern is the section in RTM SPRUJ52B , " page 7, Figure 1-1. Device Top-level Block Diagram , Under this figure there is this note:
• A solid black box indicates the IP is part of the Extended MCU (eMCU).
• A dashed black box indicates that some instances of the IP are present in the eMCU and some instances are present in the non-eMCU portion of the Main Domain.
"
So I am afraid that I select 1 port and It is not accessed by A72 cores but only the R5F cores of extended MCU.
Hello Mohamed,
Can I confirm that this is related to TDA4VM or TDA4VH? They are both different devices.
Hi,
So I am afraid that I select 1 port and It is not accessed by A72 cores but only the R5F cores of extended MCU.
You can access any CPSW from any core, no restriction like only one core can access until that region is firewalled by S/W.
Also, 2.5G CPSW is in Main domain can be access by A72.

Thanks Sudheer.
As Sudheer mentioned, there is no restriction on accessing any of the CPSW9G ports on A72 core.
