Thank you very much for your reply.
一.Explaining according to the documentation (Eth_TS_T40D11M40I2R0\doc\RTD_ETH_IM.pdf), after adding the Eth module, there is no explanation of how Eth_Memmap.h is generated.I think this is not written manually, it should be compiled and generated.
二. After adding the Eth module, I Compile GoldVIP-S32G3-1.11.0\realtime\s32g399ardb3\can-gw based on this document GoldVIP-S32G3-1.11.0\documentation\GoldVIP-User-Manual.pdf \14.4 Building the M7 Application.I don't know if there is something wrong with my compilation method。
