Hi dd, I already found a solution for my problem. I just set the physical address to 2 that it fits the condition and I used static ip now instead of dhcp. Now I can ping to the beagle and get a response. Before "CPSW0_PORT_1_PHY_ADDR" was set to zero. It is not explained anywhere why I needed to set it to 2. I was just try and error by myself.
Snippet of "cpswif.h": #define CPSW0_PORT_1_PHY_ADDR 2 #define CPSW0_PORT_1_PHY_GIGABIT FALSE regards, DS On Wednesday, February 7, 2018 at 2:05:34 PM UTC+1, [email protected] wrote: > > Hi dd, > > First I want to thank you for your contribution in efficient bare metal > programming.
