I am currently working on a COM-Express module mounted over a carrier board. The COM-Express moudle features i7 processor and 82577 onboard gigabit ethernet controller and the carrier board contains one 82574 gigabit ethernet controller.
I am using qnx 6.5.0. After booting, the onboard ethernet device(82577) is automatically getting detected as wm0 and it is working fine, but the other ethernet chip in the carrier board is not getting detected in ifconfig.
ifconfig shows only one device i.e, wm0.
What is the reason for not detecting the 82574L ethernet controller ?
Is there any driver available for Intel 82574L ethernet controller for QNX 6.5 ?
