[lwip-users] HOWTO LwIP if NO_SYS = 1

[Niraj Kulkarni]

Hi,

I am porting LwIP on Renesas 16-bit controller with no OS. After reading

1.       lwip-1.4.0.rc2\doc\rawapi.txt

2.       http://lwip.wikia.com/wiki/Porting_For_Bare_Metal

3.       http://lwip.wikia.com/wiki/LwIP_with_or_without_an_operating_system

4.       http://permalink.gmane.org/gmane.network.lwip.general/9824

I have understood that in my case “NO_SYS = 1” and All applications must be written using the raw (or native) API.

I have following quires:

1.       Do I have to implement etharp_tmr(), ip_reass_tmr(), tcp_tmr(), etc using some way ( may be Hardware time of the controller).

2.       I could not understand arguments of “netif_add” function ; specially first and last two arguments. Out of the last two functions which one I have

to implement.

3.       Is there any code ported on any controller with LwIP on it with NO_SYS = 1 , available for download.  

 

Regards,

Niraj
