When the Net+50/NetOs v4.0 boots up it sends an ICMP packet. I presume this announces the device’s address to the network. The packet appears as follows: * FF FF FF FF | FF FF 39 39 | 39 39 39 39 | 08 00 45 00 […999999…E.] * 00 24 00 01 | 00 00 3C 01 | BB D9 07 5C | BB A3 FF FF [.$…<….…] * FF FF 09 00 | 2B F6 01 02 | 07 08 07 5C | BB A3 00 00 […+….…] * 00 00 00 00 | 00 00 00 00 | 00 00 00 00 | […] Using the debugger I see that this packet is sent after the BSP calls the send packet function during initialisation. The stack seems to be: dummy2.dlo - 0x35be4 calls dummy5.dlo - 0x59a0c calls narmenet.c - eth0_start(…) Is it possible for me to modify the BSP to disable this packet being sent? Can you provide alternate dummy*.dlo files to do this? I am using NetOS v4.0 - if this has an impact I will investigate upgrading. Regards, Tim
