LP-AM243: Difference using CPSW3G and PRU for standard ethernet.

Hi Hang,

I'd like to ask that is there difference when using CPSW3G and PRU(ICSS) for standard ethernet (TCP)?

Ideally we recommend using CPSW for standard ethernet and PRU ICSSG for Industrial ethernet. CPSW is a HW switch and PRU ICSS is a firmware based implementation of switch. The memeory footprint for ICSS will be more that CPSW.

Customer's goal is to implement a 5-port standard ethernet switch using these two subsystems, is there any limitation?

What is the speed customer is looking at? Whioch stack are they trying to use? Can you more details on use case.

Hi Nilabh

Here's detail on their use case. They require at least 3 ports. One for communication with an upper computer, using standard ethernet. Two for EIP, and DLR is required. They already developed EIP stack based on TCP/IP, so they'll see EIP as standard ethernet when it comes to hardware requirements. They are looking at 1000M speed.

Hang.

I would recommend using CPSW for this purpose and this supports 1g standard ethernet.

Please ask them refer to this page for examples: AM243x MCU+ SDK: Ethernet and Networking (ti.com)

Hi Nilabh,

I will forward the references to customer.

Thank you,

Hang.
