Unable to ping one pandaboard from another with both having QNX on it   
Hi all,

I have QNX 6.5.0 running on two pandaboards (Board1 & Board2) connected by a crosswire ethernet cable. I am using a ASIX USB to Ethernet dongle on both the boards since for some reason the mac address of the ethernet port on both boards are all 0's. I use the following lines in the build script to start up io-pkt-v4 

        io-pkt-v4 -dasix promiscuous,mac=<MAC ADDRESS>,verbose=4 -ptcpip
        waitfor /dev/socket
        if_up -p en0
        display_msg Getting Static IP
        ifconfig en0 <IP> netmask 255.255.254.0
        ifconfig en0

The following are the sloginfo for both boards

RE: Unable to ping one pandaboard from another with both having QNX on it   
Is your dongle consistently working by connecting to your desktop for example. We are not getting anything on either 
side. What is the version of your devn-asix.so?

Re: Unable to ping one pandaboard from another with both having QNX on it   
What is <MAC ADDRESS>? Why are you specifying it if the Asix dongle
already has a MAC address?

Re: Unable to ping one pandaboard from another with both having QNX on it   
Thanks for the quick response.

I just added that as part of my various attempts to get the ping working. Even if I remove that, the issue exists.

Note: I had tried connecting one of the pandaboard to a desktop using the same crosswire ethernet cable. So basically 
the same setup as mentioned above, with one pandaboard replaced with a Desktop. Everything works fine. I can ping from 
the pandaboard to the Desktop and other way round too. The Desktop had the same IP/netmask as BOARD2 mentioned above.

Thanks,
Johnson

Re: Unable to ping one pandaboard from another with both having QNX on it   
The <MAC ADDRESS> is the mac addresses on the respective boards. I am not giving it a different mac address. 

I dont know how to check the version of devn-asix.so, but the build version of the QNX BSP for pandaboard that I am 
using is 201203081153, if that helps.

Thanks,
Johnson

Re: Unable to ping one pandaboard from another with both having QNX on it   
I can only imagine that there is not enough power on the USB ports to
power the dongle as well as the link. Try connecting the dongles via a USB
hub.

RE: Unable to ping one pandaboard from another with both having QNX on it   
It sounds a little too simple, but did you try both boards (individually) connected to the desktop? (i.e. dev1 <-> 
desktop, then dev2 <-> desktop)

There could be something wrong with Ethernet connector or transceiver on one of the Asix dongles (it's rare, but I have 
seen it before).

Re: RE: Unable to ping one pandaboard from another with both having QNX on it   
Hi all,

Thank you for all the responses and help. 

As Hugh had suggested, I used a powered USB Hub on Board2 and then removed the dongle on board1 and connected to the 
ethernet port on the board, and it works now. I can ping one from the other and vice-versa. So now, board1 has all 0's 
mac address and board2 has the same configuration as mentioned above.

Thanks,
Johnson
