Single Ethernet (Gbe) to multiple Ethernet connection (switch) in KCU105 board.

[rajeshkhanna]

Hi,

I have KCU105 Board, i want to connect Ethernet port to 8 port Switch. Multiple subsystems are connected to the switch through Ethernet. There is no need for sending data fast. 

How can the lwip application in baremetal can be changed to meet this new configuration. prior to this Ethernet to subsystem is 1:1.

Please help.

Hi @rajeshkhanna ,

It is not very clear on what you are trying to do. What do you mean of "prior to this Ethernet to subsystem is 1:1"? lwIP might target on one channel/link at once, and you will need to modify the source codes if you'd like to test different links.

Hi @nanz,

We need to control more modules say minimum 4 modules which have Ethernet from single board with FPGA.

All the modules are connected to hub and fpga board also connected hub. each module has its IP address.

As you understand correctly "prior to this Ethernet to subsystem is 1:1? lwIP might target on one channel/link at once".

How to use lwip application to connected to modules or any other way pls specify.

Hi @rajeshkhanna ,

You can try to modify the platform_config.h with XPAR_XEMACPS_x_BASEADDR to specify which ethernet link you are targeting.
