RE: UDP packets blocks

Hi Mauro,
OpenTCP, as Bob mentioned, folks pulled it from the market
unfortunately.  Freescale partnered with InterNice to provide an
alternative.  It has been ported to many ColdFire.
Goto following link for info and download:

TCPIP
There will be an update later this month that has many fixes and
enhancements to the stack to make it more reliable.

Subject: Fwd: [ColdFire] UDP packets blocks


Hi Bob,
thank you for your help.

I'm programming on dBUG, so I use OpenTCP stack implementation...so I'm
very unlucky!

Only one thing: there isn't a function tha can re-initialize tcpip
engine?or some functions that can directly inspect incoming TCP buffer
without callback calls? I find OpenTCP documentation, but I suspect that
version in SBCtools is customized for dBUG 

thanks  lot.
Mauro




Hi Mauro, 


	I have a problem on receiving UDP packets on a WildFiremod board
with MCF5282 micro.
	I have a program like this:
	
	INT32 udpCallback(......)
	{
	     // if packet is a command, do work
	}
	


Whoever can help you will need to know what TCP stack you are using.

May I ask if you are programming for a dBUG/OpenTCP target or a uClinux
target? If the latter, then you need to direct your question to the
uClinux-dev mailing list:

[email protected]
http://mailman.uclinux.org/mailman/listinfo/uclinux-dev

You will want to provide more background, such as the uClinux version,
target, etc..

If you are programming for a dBUG/OpenTCP target, the news is not so
good: There is little or no support for OpenTCP any more. Because of
this, we need to think about adapting lwIP to Coldfire/dBUG targets
..and that is a BIG job ..but lwIP has an active and supportive
community.

Bfn,

Bob Furber





	int main(void)
	{
	     tcpip_init(0);
	    gUdp_socket = udp_getsocket(0,udpCallback,0);
	    udp_open(gUdp_socket,port);
	   while(1) tcp_tick();
	}
	
	My problem is that after a couple of time (about 3-4 minutes)
that program runs without receiving command packets, if I send it a
packet, it doesn't execute callback. Only after 3 or 4 received packets
it executes callback and process all packets received. Packets are not
lost, because when program "wakes-up", it process all packets in the
same order that it has received them.
	I think that buffer queue hangs for an unknown cause, and then
re-starts work in the right mode when buffer has more packets.
	What might happens?
	Thank you, regards
	Mauro
