Hi Rajat,

If the Linux BSP provided by Freescale does the same thing, then I think
that you should contact Freescale and find out from them what the
problem is. Not having looked at the hardware, I don't have any further
ideas.

Hugh.

Hello Hugh,

Thanks for the reply.

The LEDs (on both switch & the adapter) do not glow even once when I
reboot the board and boot QNX through u-boot. Ditto for Linux BSP that
comes with the board :-(

However, switch & cable are allright because if I pull out the cable and
plug it into an onboard ethernet port, they work fine (LEDs glowing).
Similarly the PCI adapter works fine on a Windows PC box.

What would you say if I told you that even the Linux BSP that came with
the board is showing similar behaviour? The device "eth2" gets created,
HW MAC address correctly detected, but LEDs doesn't glow. Ifconfig shows
Link as down. I'm not sure on how to debug this down.

Your idea of u-boot putting the device in Low-power mode looked likely,
but I checked in the capabilities of the card and found that it is in
the D0 state (Powered up) :-(. Any ideas?

LED is not glowing even once, so no point of doing this....

Oh, I do see Transmitted packets being incremented in nicinfo - as
attached. Does it help, or change anything? 

Thank You very much,

Rajat Jain
