[ECOS] STM32F4 Discovery + LwIP

[Valentin BOUSSON <ml-ecos@belphegor.eu>]

Hello all,

I put aside the dynamic object loading for a while. I will come back to 
it when i'm more experienced.



Today, I have a problem to set up *LwIP* on my *STM32F4DISCOVERY* with 
the standard extension board.
(http://www.st.com/web/catalog/tools/FM146/CL1984/SC720/SS1462/PF255417)


I tried a lot of thing, as using the default configuration for eCos, 
adding packages "Ethernet common drivers" and "LwIP stack". No confilct 
appears, but an the stack doesn't seem to work at all.
I tried to use LwIP in another context, embedded in FreeRTOS, in a piece 
of code provided by ST, same results.
An idea I have concerning my problem is that I don't have a good 
Ethernet BSP.


The goal  I would like to reach for now, is just an ARP packet 
broadcast. Then, I will try to acheive more interesting protocols.
Do some of you have ever tried to use it on STM32F4Discovery + EXT, or 
have some documentation that could help me understand interfaces between 
(STM32f4 & LwIP) or (LwIP & eCos) or anything else. :=)


Thank you.
