I'm not sure it's the case in last CVS HEAD: when err_tcp is called and when we are in "connect" step, a NULL message is post in conn->mbox, and since the calling thread is waiting this event, the netconn_connect return, and the calling thread have to close the socket. During the close, any message in conn->mbox is "drained". I can't find the assertion "sys_mbox_post: mbox not full" (which should be more "mbox is full"). Is it in your port, or on the older lwIP source code ? In all cases, I'm not sure that file a bug on a very old release (0.6 if Tokmen is right) is a good thing: I don't think that any active developper will process it (remember there is lot of releases between yours and the last one). ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr <http://www.hymatom.fr/> ==================================== P Avant d'imprimer, penser à l'environnement

We don't want to upgrade to VDSP 5.0 and an entirely new version of
lwIP at this stage of our project development.
Do you know if there has been any fix for this particular bug in the
lwIP 1.2.0 , or the VDSP 5.0 port? I will file a bug anyway as Kieran suggested.
What could possibly go wrong if I simply ignored this assertion for the
time-being?
Thanks and regards,
Aparna

Hello
I think the February 2007 update of VisualDSP has lwIP 0.6. Is it
possible for you to upgrade to VisualDSP 5.0 -it includes lwIP 1.2.0?
Cheers

Subject: [lwip-users] Receiving RSTs
We are using Lwip ported onto the Analog Devices VDSP++ 4.5
(Blackfin family , Feb 2007 update) to develop a client which tries to connect
to a windows PC server using the socket connect() API.
When the Windows server is not up, the PC responds with a RST
for a received SYN. The connect() API returns an error, and the client retries
connect() after every few seconds.
After retrying for the number of times equal to the
SYS_MBOX_SIZE, the code fails with the assertion "sys_mbox_post: mbox not full".
Receiving an RST triggers the err_tcp() error function which
posts a NULL message. It appears that the mbox is getting populated with NULL
messages, but these messages are not being read out at all, and so the mbox is
getting full.
Is this correct behaviour ?
Thanks and regards,
Aparna
