TCP packet filled with 'U' 1392 bytes long

Aswin C.

Hi,

I'm trying the RL-ARM tcp/ip stack on a arm7 LPC2368 from ETT (futurlec).
I succeed setting up a TCP listen socket with the EasyWeb API.
But when I try to use the TCP stack from RL-ARM 4.12 I don't succeed.

When the controller goes online, it send one packet (ARP notify) and it is filled with 'U' (55) the whole frame/packet, 1392 bytes long.

If I try to setup a TCP connection from my controller to the PC.
several packets as described above appear.

Any idea?

Kind Regards.

    All the default settings.
    Nothing I have changed. (nor in the startup file: LPC3200.c)

    Net_Config.c :
    only TCP & UDP enabled. (and ethernet ofcourse)
    dhcp & netbios disabled.
    Arp notify disabled.
    #define MEM_SIZE 2000 (== Default: 8000 bytes )

    Startup file:
    there is a setting:
    Heap Size: 0x0000 0000
