MCU-PLUS-SDK-AM243X: Enet LLD port combinations on single R5 core

Part Number: MCU-PLUS-SDK-AM243X

Hello,

I am looking for clarification on which combinations of Ethernet ports are supported in the Enet LLD Driver. The release notes for version 8.04.00 of the MCU+ SDK for AM243x and AM64x both say "Independent ICSSG and CPSW drivers execution on same R5 cores not supported." Is this only a temporary issue or will this not be supported in the future?

According to another thread, this was being worked on 4 months ago for release 8.04.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1108529/am2434-can-cpsw-and-pru-icssg-enet-be-used-together/4112865?tisearch=e2e-sitesearch&keymatch=cpsw%252520icssg#4112865

Can PRU_ICSSG0 and PRU_ICSSG1 ports all be configured independently on one core? For example, use PRU_ICSSG0 ports 1 and 2 for EtherCAT MDevice with cable redundancy, and PRU_ICSSG1 for the lwIP stack?

Thank you for your help.

    Hi Brian,

    Running the CPSW and ICSSG on different core is supported in our SDK. 

    Currently we don't support running CPSW and ICSG on same core. Will share once the plan is same is available.

    Regards,
