Recently, I came across the problem with debugging Ethernet application. I've got switch KSZ8863MLL connected to BF-537 processor. BF-537 is loaded with LwIP application. It displays that link established but ping fails. So, it's hard to narrow down the problem since it takes to go through Ethernet driver code. I've read through EE-315 and made all necessary changes but still no luck. I also turned on all the statistics in TCP plug-in but it doesn't seem to work at all (at least no messages come up on the console window). So, the whole process of debugging virtually comes down to wild guesses.
Could you give some guidelines on how can I go about debugging that kind of issue? May be some key points in code to pay attention to.
Thanks in advance.
