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
