Hallo,
i have a big problem with my DHCP/IP and ping.
When i start my STM32F4xx system and wait for IP from DHCP, i get successfully a IP.
But when I then try to ping my system, I get no response.
BUT…
When I start the ping cmd "ping -n 999 x.x.x.x" before I start the system, the ping is ever successfully when the system is started.
What am I doing wrong?
Here are fragments from my src:
