I’m using lwip 1.4.1 with a TI eval board. When I ping the
board I get an echo response however the checksum value is zero. On the pc side
I get the message “request timed out”. Using a network analyzer and pinging
anything else on the network the checksum is not zero. When stepping through
the lwip code it does appear to generate a checksum but apparently it’s not transmitted?
I’ve tried setting many options but no joy. Do you have any suggestions? It
appears the problem I’m having could be the same as another user describes on an
Part Two: I’d like to be able to ping using the hostname. I
enabled DNS and NETIF_HOSTNAME as others have suggested but when I ping the
default hostname “lwip” I get the response “Ping request couldn’t find host
lwip”. Any suggestions? Ultimately I’d like to be able to enter the hostname in
a browser to access the web server. To get the browser working with hostname do
I need to implement mDNS (Bonjour protocol) for users on Apple devices and
LLMNR for Windows users or is being able to ping using the hostname enough to
have it work in the browser?
