Hi all.  I am working on a lwIP port to the Beaglebone Black bare-metal (no OS). 

So far the stack seems to work with the echo server and http server. 

I am working on a UDP server/client now.  I can send a single packet from one 'bone to another. 

I cannot send a series of packets a few seconds apart.  Only the first one gets thru.  Nothing on the IP layer either. 

I must be doing something wrong setting up PBUF or the PCB.

I am running out of options, anyone have an idea?

thanks.................dd
