File system & networking problems

Hi,

I am developing a custom board using the DS80C400
based on the networked speaker and TINI dev board
schematics. I have downloaded the example programs for
developing in C using keil’s uVision2 and have
modified the start up file to run from bank 20 (512K
of RAM). My aim is to get the TINI to request files
from a TFTP server running on a windows PC, store them
in its file system, and host them on its HTTP server
(basically a cut down version of the time server
example). Unfortunately I am having a few problems :-(
and would appreciate any help.

Problem 1	File system problem
When I first power up my board and give it ONE reset
(the power-on reset doesn’t work at the moment) I
download the file system example program and run it.
The program gets as far as initialising the file
system and then freezes. Upon a reset I run the code
again and the example works fine (with the result from
finit being 0 so it looks like the first time the
program ran it created the file system).

Problem 2	Network problem
When I first power up my board and give it ONE reset
(the power-on reset doesn’t work at the moment) I
download the TFTP example program and run it. The
program runs through correctly, getting the files and
printing their contents. Upon a reset I run the code
again, but this time the TFTP program prints “Error in
TFTP_FIRST”. Both setftfpserver and tftp_init return
0. I had Analyzer running to sniff any MAC traffic and
both times I saw an ARP request but they where
different.

Fist time (when it worked)
In the ARP packet the destination MAC address was
FFFFFF-FFFFFF and destination IP address was
169.254.100.2 (which is the correct IP address of the
windows machine)

Second time (when it didn’t work)
In the ARP packet the destination MAC address was
FFFFFF-FF6402 and destination IP address was 0.0.0.0

Any pointers much appreciated,

Mark
