There is several way to create a port. One I can suggest is :

 

- select the API you want to use

- prepare your lwipopts.h file

- if you decide to use sequential API, start to create your sys_arch port (http://lwip.scribblewiki.com/Porting_for_an_OS)

- next, create your initialization framework, and use loopif interface in a first time (look http://lwip.scribblewiki.com/Initialization_using_tcpip.c if you use one of the sequential api, current HEAD "contrib/ports/msvc6" port you also help you, since it's updated)

- now, you can create any simple application to check the stack between two local "process" (a client and a server, by example, look the "contrib/apps/httpserver" or "contrib/apps/httpserver_raw". Since the loopif is "only software", you can check if the stack is working without start to develop your device driver.

- last, implement your device driver (look http://lwip.scribblewiki.com/Writing_a_device_driver). You can also look some "old" ports to see how are design there driver. But I'm not sure there is lot of them updated.

 

Once again, this is a way to create your port. The advantage of this one is you can do most of the job without any real hardware reference...

 

I hope it help you...

Hi all.

Someone has a port for NXP lpc236x microcontroller family (or similar) ?

or

someone can help me to develop a port?

or

someone has an example for NXP lpc236x microcontroller family (or similar) ?


thanks to all.
Piero
