Hi John and Chris,
Thanks guys, I am really thankful to you. John, thanks for being so
patient in answering my dumb questions. I could run the test examples
I am not still out of questions yet :)
Well I would like to know the way to add Simon's lwIP 1.3.0 which i
downloaded. Is there a procedure to take out the old lwIP and add the
new Simon's lwIP ?
I see the lwIP folder and also a ecos database file. So I thought its
a good idea to ask ecos experts here.
My goal is to run the Raw HTTP server example using lwIP 1.3.0(Simon's port).
