Re: [lwip-users] Xilinx PowerPC receive udp messages

Hi Peter,
Matthew is right. Check if your ethernet interrupts are connected
correctly and enabled accordingly. All the drivers code from EDK are
wrapped with extern C, so this shouldnt be an issue.

Is your hardware connected properly?

In order for the EDK to properly detect the use of interrupts for Ethernet,
you need to connect your Ethernet interrupt output to an interrupt
controller or directly to your processor.  Otherwise it won't even try to
link the interrupt code for the EMAC.

I wrapped the file that includes the above call XIntc_RegisterHandler(..)
but that did not help.
All files in lwip and the xilinx emac seem to have the

#ifdef __cplusplus
extern "C" { ...

around their headers.

The function is defined, when I use Ctrl+clicking onto XEmac_IntrHandlerFifo
the Platform Studio SDK points me to the function, which is located in
xemac.c.
But the linker does not find it ...
