Hi, 

I'm trying to construct a wireless communication network using the p2020rdb-pca.

After installing wlan cards using the PCIe interface on the p2020rdb-pca, I used a command 'lspci' and
got the following messages, which imply "the wlan cards are not recognized".

--- Messages ---

0001:02:00.0 PCI bridge: Freescale Semiconductor Inc P2020E (rev 21)

I tried to configure the Linux kernel like the belows and got the same result.

Bus options --->
[*] PCI Express Port Bus support
[*]     Root Port Advanced Error Reporting support
[*] PCI Express ASPM control

There was no result of recognizing the wlan cards.
How can I solve this problem?

Please provide additional information:

1) U-Boot booting log text

2) photo of the RDB board with installed PCIe card

3) positions of all on-board switches

Hi, thanks for the fast reply.

The attached files include a booting log text, photos of the RDB board with PCIe cards and on-board switches.

If I didn't attach any files in need, please let me know.

Thank you in advance for your help.
