Re: [lwip-users] Assertion failed in TCP code

[David Hammerton]

Hi Kieran,

Thanks for your reply.

Most of that code is from a sample app from Atmel, and I can't remember exactly what it's doing. I'll check it out on Tuesday, when I'm back at work, and let you know. What should it be doing, though?

Cheers

David

That looks like your bug.  How is the MAC thread passing packets up to
the stack?  Also, can you show us your "netif_add()" function call?

Thanks
