How to construct Ethernet over PCIe for S32V234

[soccercheng]

I have the following questions about constructing the development environment using the Ethernet over PCIe on S32V234

• Which PICe switch with NTB support should I use ?
• Do I need a PC as root complex ?
• Any software packages that are required ? and how do I get the source code ? 

BTW,

Is there a tutorial for this ?

Hello,

For general recommendation about PCI There the hardware desing guide of S32V234 EVB:

For PCI enumeration please follow the user guide of the linux BSP:

Hello,

Many thanks for your input, I've found the information I need in the user manual and Linux BSP.

But I've got little confused about the following architectural questions

• Why, in BSP 23.5, the "vnet"  driver is only included in s32v234bbmini, but not in s32v234evb and s32v234pcie ?
• In the PCIe Virtual Ethernet sample application, S32V234-EVB running as RC and the S32V234-PCIE running as EP.
  • Does this mean EVB and PCIE can talk to each other through socket connection only ? Is the EVB able to play as an NAT and route the socket packet to EXTRANET ?
