Hello,

There is a PCIe/Ethernet bridge mentioned on EthernetSwitch.pdf which I found on CDDS training material for J721e. (See picture below).

Could you please let me know where I can find more information about this use case & documents?

Also if there is an demo available to demonstrate this use case , could you please point me that as well?

Thank you,

Satish

Satish,

The diagram does not ring a bell to me as a packaged demo. Can you let me know the specific training module or link to the CDDS?

If I guess, it seems to be a concept system built on top of three modules::

A standard PCIe EP function (Commonly EP, but can also be RC function depends on system, there is also an RC driver page at the same SDK link):

Ethernet Switch Firmware (on R5) and virtual MAC in Linux:

software-dl.ti.com/.../index.html

software-dl.ti.com/.../J7_CPSW9g_virt_mac.html

Please take a look at above three references and let me know if you need further information.

Satish,

I can confirm these 4 diagrams are illustration of use case based on the Ethernet switch, They are not canned demos, but you can build out your solution with the switch software and additional modules.

The three links I sent in the earlier reply give you user guides for each of the modules in involved in the 4th diagram.

regards

Jian
