The lwip stack stops responding completely when an IPscan on the subnet is performed. This spews out a series of ARP requests.
It looks like the Ethernet MAC stops generating interrupts because ethernetif_input() is no longer called. lwIPstats() reports an ETHARP drop and lenerr which makes me think the MAC is is not being serviced fast enough. I'm using a modified STR9 demo from FreeRTOS with lwip 1.4.0. My lwipopts.h settings are using the defaults for the most part. Anyone else have this issue? -Dave _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
