[FAQ] MCU-PLUS-SDK-AM243X: What are the possible Ethernet configurations on ICSSG0/1

Hi,

PRU-ICSSG currently supports DualMAC mode and Switch mode on each of the instance.

This opens up the possibility of many combinations across the two ICSSG instances ICSSG0 and ICSSG1.

The following is a list of all supported configurations and the ones which are checked are working configurations.

1. ICSSG0 supported features: (Layer2 and LwIP)

   • Port1 Mac mode

   • Port2 Mac mode

   • Port1 + Port2 MAC mode (DualMAC)

   • 2-Port Switch mode

2. ICSSG1 supported features: (Layer2 and LwIP)

   • Port1 Mac mode

   • Port2 Mac mode

   • Port1 + Port2 MAC mode (DualMAC)

   • 2-Port Switch mode

3. ICSSG0 + ICSSG1 Supported features: (Layer2 and LwIP)

   • ICSSG0 mac mode port 1/2    + ICSSG1 mac mode port 1/2

   • ICSSG0 mac mode port 1/2    + ICSSG1 mac mode port 1    + ICSSG1 mac mode port 2
   • ICSSG0 mac mode port 1        + ICSSG0 mac mode port 2    + ICSSG1 mac mode port 1/2
   • ICSSG0 DualMAC mode(1+2) + ICSSG1 DualMAC mode(1+2) [4-Port MAC mode]

Note:

• AM64x/AM243x EVM do not have ICSSG0 (HW limitation). SO MCU+SDK examples/testing is limited on iCSSG0.
• If you are using ICSSG0 and ICSSG1. Then, in sysconfig always add ICSSG0 first, then add ICSSG1 instance.

For latest update please refer MCU+SDK pages:

• AM64x MCU+ SDK: Ethernet and Networking (ti.com)
• AM243x MCU+ SDK: Ethernet and Networking (ti.com)
