> lwip-users@ > https://lists.nongnu.org/mailman/listinfo/lwip-users Thank you sooo much Simon... This really worked for me. I was such a fool that I didn't consider typecasting. But one problem is why I can't ping to my device? Though some NS, NA packets are getting Tx/Rx from my device to PC, I get "General failure" message in reply whenever I'm pinging IP6 address of my device. Please help me for that. It would be highly appreciated.
