Re: [lwip-users] LwIP and IAR Workbench

[Akshat Bisht]

Jifl, the only concerns i see are :

1. Difference in the data types of the packets, which a function in the middle will have to sort.
2. IAR TCP/IP calls the input function of the lower layer, whereas in lwip lower layer calls the upper layers. i.e. PPP calls IP in lwip for in-coming data and IP calls ethernet(or PPP) in IAR.

As for including lwip with IAR TCP/IP i'm already including files necesary for PPP from the lwip stack. I'm hoping to removed IPv4 and TCP part of lwip in my implementation. Am i doing a flaw?


Thanks and Regards,
AB

You mean try to include lwIP's PPP in the IAR TCP/IP stack by pretending
it's an ethernet driver? I would not be optimistic about that.

I think it would be more likely to work if the lwIP stack was in there
alongside the IAR stack.

I'm around now.
