Re: [lwip-users] Kernel Implementation into a Blackfin Processor

[Paul C]

Hi

If you read through Adam's examples, he explains how
to write a single threaded application by using 
defines and function stubs for the semaphores and 
mailboxes. If you have to change the LWIP code then
there is a good chance that you are doing something
wrong.

If you are starting out then it is best to turn on
all the debugging output. First thing you want to 
do is write your main application as an endless 
loop which calls lwip. Then you need to debug
your ethernet/slip/ppp/loopback input/output code so 
that lwip receives and responds to pings.
Once that is working you will need to use a timer
to call the tcp code every 100ms. Then LWIP is
pretty much done, go and write your application!
