Using v2.8.6, when I build the IPv6-DHCPv6 example program I get the compiler warnings below.

These warnings are the unfortunate result of us adding the custom printf flag '%I" to print an IP address object. We are looking in to how to remove the warning next time we build gcc, but for now, its safe to ignore.

Using v2.8.7, I built this example and ran it on a MOD5441X. It displays the normal IPv4 information received via DHCP, and the link-local IPv6 address. Since the example is named DHCPv6, I expected to see a routable IPv6 address displayed. Since it didn't, does that mean no DHCP request was made, or that the server doesn't support DHCPv6?

It means it found no V6 router.

This example should work in vs3emu? Its very simple, but it does not work. How does the cleaning receiver buffer and UART_ST_RXFULL?
