Hi,

I am having some difficulty setting up an ip stack on our platform which uses QNX running on an imx controller. I have 
read through all the documentation I can find on the QNX web pages regarding the ip stack as I was unfamiliar with it.

What I now understand is that I need to load the QNX supplied driver for the imx FEC. I am using….

  io-pkt-v4 -d mx53 mac=xxxxxxxxxxxx

With ifconfig I get…

  fec0: flags=802<BROADCAST,SIMPLEX> mtu 1500
  address: xx:xx:xx:xx:xx:xx
                media: Ethernet none

When I connect a cable between my PC and our platform the LAN connection reports “connected”. This possibly indicates 
that the HW is working ok.

The next step is to assign a static ip address to this interface. I try…

                ifconfig fec0 192.168.128.161

This hangs. It looks like the imx has stopped so I am assuming, maybe incorrectly, that the driver is the cause of this.


I tried:

  if_up -p fec0

which has exit status of 0 which means the interface is present but not necessarily configured.

  if_up -a fec0

returns  "if_up: retries exhausted" with exit status 7

No sure exactly what the 7 means but this implies that the interface is not configured.

Any ideas what I am missing in configuring the interface? On the same platform the asix driver for usb dongle is working
 fine.

What functions in the driver are called as a result of the ifconfig command? I couldn’t find this information on the 
QNX support pages. With this I could attempt to debug the problem.

I am also wondering if my setup is missing something. Do I need to run anything else? Are there any tools that would 
help diagnose the problem?

Unfortunately I am new to the finer details of networking and am learning as I go so any useful information would be 
appreciated.

Thanks
Simon
