I have received a Beagleboard RevC4 with a QNX image on it.

i have connected a USB-Ethernet D-Link E100 that is suported by my image but I do not succeed to get an IP adress for 
the board.

here are the commands I have run
  [code]io-pkt-v4 -d asix -p tcpip,verbose
  waitfor /dev/io-net/en0
  dhcp.client
  [/code]

Hereunder is the result of ifconfig command.
[code]
# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
        inet 127.0.0.1 netmask 0xff000000
en0: flags=80008a43<UP,BROADCAST,RUNNING,ALLMULTI,SIMPLEX,MULTICAST,SHIM> mtu 1500
        address: 00:80:c8:3b:0f:72
        media: Ethernet 10baseT
        status: active
        inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
  [/code]

as you can see the network seems to be established but I have no IP address;

here is the sloinfo report

[code]Jan 01 00:02:00    5    14     0 tcpip starting
Jan 01 00:02:00    3    14     0 Unable to attach to pci server: No such file or directory
Jan 01 00:02:00    3    14     0 Using pseudo random generator.  See "random" option[/code]


Any idea on what is going wrong? previously I had a RevB with an other QNX image and the setup was ok :-(

Re: BeagleBoard RevC4 and D-Link E100

One thing that does tend to happen with USB on these eval boards is power-limiting.  You might want to try plugging into
 a powered hub and see if that makes any difference. Haven't seen it before with a wired dongle, but it's common with 
wireless dongles.   An output from nicinfo would be helpful to see if packets are flowing.

  Does the USB subsystem work with other devices?

Re: BeagleBoard RevC4 and D-Link E100

I am currently using a power hub. the same setup was working correctly with my previous RevB board and an other QNX
image loaded on it.

#I also see some differences in the /proc/boot directory between my two devices.
I have the following on RevB board and not on RevC

should I try to copy them to my other board?

Re: BeagleBoard RevC4 and D-Link E100

I have just tried the exact same image on a RevC3 board and then network is working fine.
but not on the RevC4

one difference between the two is the UBoot version that is used and also the following
RevC3
In:    serial usbtty 
Out:   serial usbtty 
Err:   serial usbtty 

RevC4
In:    serial
Out:   serial
Err:   serial

but I did not succeed to change it with the setenv command.

Re: BeagleBoard RevC4 and D-Link E100

I have found a solution. instead of running network.sh during boot time I do the following.

once th boot is finished and logged in as root
I unplug/plug my ethernet dongle and then run network.sh and then I have an IP@

here is my network.sh 

echo Waiting 5 seconds before starting network stack.
sleep 5
io-pkt-v4 -d asix -p tcpip
waitfor /dev/io-net/en0
dhcp.client


so my question now is why does it work once the boot is finished and not during boot.
do I need to wiat something due to OTG initialization or so?
