TDA4VM: Expansion board

Hi team,

The customer has two network expansion boards (OPN# J7EXPC01EVM, J721EXENETXPANEVM) mounted directly to the evaluation board and booted with the SD that comes with the evaluation board from the factory. The network port was found to be unavailable. Is it required additional action to match this expansion board? Or could you help share instructions for using the expansion board? 

&cpsw0 {
	/*
	 * Disable cpsw0 since cpsw9g_virt_mac is the default Ethernet
	 * controller. cpsw0 is enabled with overlay for native
	 * Ethernet driver support.
	 */
	status = "disabled";
};

Which board does this cpsw0 correspond to? What does the other board need to do to use it? There are currently ten network interfaces on the evaluation board, and only MCU ENET is available. 

Could you help check this case? Thanks.

Best Regards,

Cherry
