DP83TD510E-EVM: EVM communication issue

Part Number: DP83TD510E-EVM
Other Parts Discussed in Thread: USB-2-MDIO, DP83TD510E, DP83822I

Hi sir,

A customer has the following query, can you give your advice on this issue?

I'm trying to create a demo based on 2 evaluation boards DP83TD510E-EVM using 10Base-T1L technology.

Both boards are connected together via a 10 meter SPE cable and each board is connected to a laptop via Ethernet cable.

Both Boards are also powered through USB (No external power supply).

The idea is to try to send a packet from laptop A to B. But I am strugling to understand how the boards are supposed to work.

What i managed until now is to install the drivers for windows, use USB-2-MDIO to open Board's port. I also read 0 in each register so i don't know if that's even a problem.

Thank you for your clarification in advance.

Regards,
