[FAQ] TDA4VM: How to get CPSW9G virtual interface functional on TDA4x/DRA8x SDK versions 7.0 onward?

Part Number: TDA4VM

When I build EthFw on SDK 7.0, I don't see the CPSW9G virtual interface on Linux coming up. This was functional in previous SDK 6.2.
What changed in SDK 7.0?

  • Starting from RTOS SDK 7.0, by default EthFw is integrated into vision_apps to enable running openVX nodes and EthFw on mcu2_0 core.
    Due to this the default memory map is setup for running EthFw with vision_apps and EthFw needs to be built from vision_apps by doing below commands.

    cd vision_apps
    make -s pdk ethfw vision_apps

    Note: The app_remoteswitchcfg_server.xer5f binary built by doing ‘make ethfw_all’ from EthFw folder will not work for virtual cpsw9g interface in SDK 7.0. This was the command used until SDK 6.2.
