DM8168 PCIE wifi module

Prodigy 80 points

I try use wifi module at 8168EVM.

Work on Realteck R8192E and Broadcom BCM43224.

Two modules both have problem.

R8192E is sometime firmware load fail at 3rd data phase.
BCM43224 is read fail at specific adress.

Code
return R_REG(oi->osh, &cc->sromotp[wn]);

Error message
Unhandled fault: Precise External Abort on non-linefetch (0x1008) at 0xcd1d082e
Internal error: : 1008 [#1]
last sysfs file: /sys/devices/pci0000:00/0000:00:00.0/0000:01:00.0/firmware/0000:01:00.0/loading

Is PCIE driver setting problem? Or wifi module problem?

    Hi Tae,

    Make sure you are building/configuring kernel that supports these cards. See if the below links will be in help:

    I found also that Intel Centrino Wifi PCIe card works good on the DM816x TI EVM.

    Hello Pavel:

    Which Intel Centrino Wifi PCIe card did you use? Did you have to modify the standard driver? If so can you post a link to the driver that you used?

    I am facing issues with the 802.11ac cards.

    Thanks
