[riot-users] Nucleo-64 + ENC28J60

[Giuseppe Tipaldi]

Hello everybody:

I'm using a nucleo-64 board (STM32L476) to interface it with an ENC28J60
transceiver (mounted on external pbc).

Hardware connection:
___________________________________

| CN9: D2              | <-----> | J1: INT         |

Please take a look to attached files:
[1] Makefile
[2] main

Goal:
I would assign it an IP address from my DHCP.

Problems:
ifconfig doesn't print anything (because iface == null) and the boot up
doesn't log errors
I think there's a problem with the ENC28J60 probing/registering, I don't
see any output of the driver when I turn on the debug MACRO of driver
enc28j60.
I need help.

Best,
Giuseppe.
