VxWorks Image Download Problem thru FTP Server

[Balaji Shanmugam]

Hi All

I am facing a problem while downloading my image from my host
machine to the target through FTP Server. It frequently gets
disconnected saying

"Transfer Aborted"
"Got File d:\tornado\target\config\balaji\vxworks unsuccessfully"
"Timeout while sending data"

FYI , the LAN i am having both target and host are 10BaseT one and the
Ethernet card in my target supports 10BaseT. (My host's n/w cardis
100BaseT).After a few ( 5- 10) trials , it will get connected and
starts the VxWorks image ending it in the vxworks prompt.

The next problem i am facing after downloading is "Target server
disconnection"

Once after successful downloading when i connect the target
server and open up a shell it is working fine.

When I left the shell with no activity for a small epoch, the
connection with the target gets disconnected and so I am unable to
continue with my debugging by downloading into the target server my
downloadable image.

Please help me out.

Thanks and Regards

Hello,

You don't say much about your network wiring, in particular whether
you are just connecting the two machines back to back, or going via a
hub or switch.

If you are using back to back (i.e. a direct cable between the two
machines), then there are two things you should consider:

1) Make sure that it is a "crossover" cable and not a normal cable. I
assume that since it can connect this is OK.

2) Try to disable the autonegotiate feature on the host card as this
frequently causes problems in back to back configurations. Fix the
host at 10Mbps half duplex.

If you can, place a 10Mbps hub between the two boxes. That will
simplify the autonegotiate issue, and the cabling. You will also get
some LEDs in most cases that can help you identify which part of the
network is not coming up correctly.

HTH,

John...

Hi John,

Thanks for your reply. The network wiring is thru a hub . Both the
host and the target are connected to a 10Mbps LAN.

I even tried with a crossed cable ( when connected back-back), but
it doenst get connected. At that time i hadnt done the AUTONEGOTIATE
OFF .. Will you please tell me how we can set off the autonegotion..

Thanks in advance
