TDA4VE-Q1: TDA4V mid eco lwIP Domain Communication Questions

Part Number: TDA4VE-Q1

Hello, TI experts.

We are currently designing a system using the TDA4V mid eco, planning to run Autosar on the MCU domain and QNX on the main domain.

We intend to develop using SDK version 9.X. Our system configuration will connect only one ethernet PHY to MCU_CPSW via RGMII in the MCU domain.

According to the documentation (https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/09_00_00_02/exports/docs/pdk_j721s2_09_00_00_45/docs/userguide/j721s2/modules/enet/enet_lwip_userguide.html),

it seems possible to configure a virtual network between cores using lwIP.

I would like to inquire if it's possible to facilitate network communication directly to the main domain, not just the MCU domain, from external through the ethernet PHY using this feature.

Additionally, I'm interested in knowing if network communication between the MCU domain and the MAIN domain is possible when a virtual network is configured.

    Hi,

    TDA4VE supports only CPSW2G.
    We don't have Inter-core virtual Network interface for CPSW2G applications.

    Also, LWIP is RTOS based network stack from TI SDK. We don't have Network stack support in AUTOSAR.

    Yes, but TI application supports this via Ethernet Firmware form MCU2_0 core using RTOS for CPSW5G/CPSW9G in other TI SOCs.


    For CPSW2G no support for Ethernet Firmware So, above may not be possible for TDA4VE.
