[ECOS] timeout in tftp_client_test.c

[ECOS] timeout in tftp_client_test.c

[HG]

Hi All,

I am getting timeouts in this test in the following test case for the
tftp_get call :

server used is solarwinds tftp server on an nt 4.0 , ip address of
application is set via the config tool :address setups for eth0 , the ip
address is different from the redboot one.
the 82559 ethernet driver is used with 8 tx & rx descriptor, the freebsd
stack is used with the default configs , the cvs is that of a snapshot of
early april this year. The program returns from the call with no error and
only a few percent of the file transfered. The thread apparently continues
and the server reports continued timeouts until the board is restarted.

the tftp download with redboot works ok and is used for the download of
files sizes  of  > 1meg successfully . Throughput is not great but at least
no timeout.

Are there some configuration options for the library that should be checked
that are different from the defaults , any patches that could be useful ,
setup issues to check ??????

many thanks for any help

Henri

If your RedBoot is using bootp/dhcp for its IP address, then if your eCos 
application does the same it will probably get given the same address, 
causing a conflict... the eCos application always passes incoming packets 
to redboot and if redboot takes it (as it would if the address matched) 
eCos will never see the packets.... so you will never see the reply from 
the TFTP server.

I recommend trying some of the simpler network tests to start with to give 
you some confidence in the setup.
