Discussion Groups | Rabbit-Semi | FTP, FAT and TCP problem
This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
FTP, FAT and TCP problem - Ari Barbakos - Sep 11 7:57:56 2008
Using a RCM4300 with a 1GB SD Card as a data logger with messages
received via a TCP socket.
The RCM4300 also acts as an FTP server so the data logs can be
downloaded via FTP.
This all works perfectly fine.
However when I add the functionality to send a TCP packet from the
RCM4300 a strange situation arises. If there has been no previous FTP
connection to the device the messages are sent correctly. However if the
device has been accessed via FTP before a TCP message packet has
attempted sending the connection will continually fail. Conversely if
the TCP message packet has been sent before a FTP connection has been
established the FTP connection will never occur.
If the FTP connection has been established before a TCP message has been
sent the TCP message code fails at this point in the code:
tcp_open(&sendSock, 0, resolve(ip), port, NULL)
- The IP is valid and the port is 8000
To me this is saying that you cannot open a socket if there has ever
been a FTP connection.
If an TCP message has been sent before an FTP connection has been
established the FTP always fails to establish a connection.
After tracing the code in the ftp_server.lib line 1840, in the
ftp_tick() function
if(sock_established(state->s))
always returns 0 and never establishes the connection.
I am using firefox 3.0.1 to establish the FTP connection. I have also
used the FTP client FileZilla 3.1.2 and this has also failed.
I hope I have provided enough information. The situation is quite
confusing if any clarification is required I will happily try to provide
it.
It is essential that ftp access and TCP communication be implemented on
the one controller.
Any suggestions would be greatly appreciated.
Thanks in advance.

Hmm,
I'm actually having that exact same problem...any solutions?

Sounds like there are not enough TCP sockets or buffers defined.
