[lwip-users] Xilinx -> Microblaze -> NetIF Question

[Lachlan Grogan]

Hey All,

 

I have encountered an issue, not to sure if it is my poor coding, a limitation of lwip, or one of these memory alignment issues i've been reading about.

 

I have the following example code:

 

void foo_bar()

{

    struct netif * default_netif;

 

    .... Init Code Goes Here

 

    default_netif = netif_add(......)

 

    ... more code goes here.   

}

 

This works fine and my system is up and operational.  However I wish to do the following:

 

 

struct netif * default_netif;

 

void foo_bar()

{ 

    .... Init Code Goes Here

 

    default_netif = netif_add(......)

 

    ... more code goes here.   

}

 

 

This code does not work, netif_add(..) does not return, and crashes my MicroBlaze. 

It is far superior for me to have the pointer to the netif "global" so as other functions can make use of it.

 

Can anyone suggest a solution, or see anything stupid that im doing?

 

Kind Regards
