Hello,

In the device's diagram, we can see there is no access way between C66 and MSMC. But I have tried in EVM_TDA4, we can put the stack, program or heap of C66 in the MSMC. What is the way of C66 to access MSMC?

In this diagram, we can see C71/A72 use a "coherent interface" to access MSMC. I want to know the use of this interface, What is the difference between C66/R5F and C71/A72 access to MSMC？

Hi,

Тhe device diagram gives overview of the device and can not show all connections between IPs.

- between A72SS/C71SS and MSMC there is a direct access (not via system CBASS)

- between R5FSS/C66SS and MSMC there is no direct access, just via system CBASS interconnect and then thru NAVSS0 which is connected to MSMC thru North Bridge (you can check also Figure 6-1. COMPUTE_CLUSTER0 Overview in Chapter 6).

Regards,

Yordan

THX a lot!

So in the device diagram, there should not be a line between R5FSS and MSMC. Is that right?

Happy THANKSGIVING Day！

That is correct. We are expecting a TRM update.

Best regards,
