A bit more details about "my stuff": GCC from CodeSourcery and usage of M52235EVB. From ethereal sniffing, the 52235 sends an ARP request for the configured gateway address, and receives a valid reply to this.
I guess this is parts of the answer (correct me, if this is incorrect):
- use power-up code similar to the niche web-server (without the tasks and web-server)
- call inet_timer() from timer_isr()
- call packet_check() from timer_isr() (??)
These attempts on simple low-level data transfer has failed:
- send data with udp_send() (no relevant data found in ethereal)
- receive data by using udp_open() and waiting for callback function (no callback)
- listen on TCP port with m_listen() and wait for connect (no callback when attempting to connect to 52235 with netcat)
Does anyone have a tip or success story to share with us?
