Do I have a faulty LAN chip?

[philmacu]

#define ETH_ADDR        0
#define ETH_POWER_PIN  -1
#define ETH_MDC_PIN    23
#define ETH_MDIO_PIN  18
#define ETH_TYPE      ETH_PHY_LAN8720
#define ETH_CLK_MODE  ETH_CLOCK_GPIO17_OUT


maybe you have not add :
#define ETH_ADDR        0

Thank You, yes I had forgotten the define for ETH_ADDR

I have now got the unit connecting via Static IP (which is what I need) to a router. I have to travel next week but I will upload a video on my YouTube channel when I get back.

Many thanks to you sir.
