[lwip-users] DHCP Lockup

[Bill Lawson]

Does anyone know what could cause dhcp_start() and dhcp_stop() to never 
to return?

I can call dhcp_start() once, and if I get an offer immediately 
everything is fine.  However, I only send one discover message.  If I 
don't get a reply to that message nothing more happens.

I've tried calling dhcp_stop() (after a timeout) so that I can restart 
the transaction, but dhcp_stop() never returns.  I've tried calling 
dhcp_start() again without stopping it first but the second call to 
dhcp_start never returns.

Does anyone have any idea why this might occur?

Thanks,
Bill
