S-400 internal ethernet controller


#1

Hi.

Since we’re going to design a custom board for S-400 module for a specific application, we’d like to use module builtin ethernet controller + phy (Module pins 2,4,6,8, plus10,11 for leds).

How does “porting” code detect whether to use either ENC28-SPI-based or built-in controller?

What actually happens if both J11 magnetics and ENC28 spi module are connected at the same time?

Thanks!


#2

You can connect both and use both, just like if you also have Wi-Fi


#3

Use both at same time or alternatively (ENC28 or builtin)?


#4

@ Gus : so there will be (eventually) two NetworkInterface istances enumerated (3 if using also wi-fi), right?

Is there anything special at user firmware level in order to enable a specific NetworkInterface for TCP socket operations?

Thanks.


#5

Today you can use one or another but it is possible in the future that we may support using both simultaneously.


#6

So at boot time we have to call:



?

#7

This one or the ENC28 one if it is used.
