Hi,

I am trying to port Intel Centrino-N 135 wifi module into iMx6q. (Android ICS version, code base is R13.4)

For figuring out what issues are I met, here are my procedures :

1. insmod cfg80211.ko

2. insmod mac80211.ko

3. insmod iwlan.ko debug=0x43ffff

Till now, those output messages are quite ok.

Then I started the wpa_supplicant, then those messages are coming :

Hi,

I've fixed this issue by other way.

As we know that the driver for Intel wifi modules came from backports-3.xxxx... (or compat-wireless-xxxx)

What I did was :

I download many different version of intel wirelss driver and try to port into my board.

And I found one version of these can work without modifying may code in driver.

This is just what I did and how I fix my issue.

Thanks.

Hi Tony,

Looking at detail on the error dump i could say the following:

Even your are using a intel PCI express. Internally they use a CSR wifi ip.

The setup registers which could be configured at boot time on CSR chips are call PSKEYS like

"CSR_HW_IF_CONFIG_REG", "CSR_UCODE_DRV_GP2" , etc.

Those registers are documented in NDA technical document provided by CSR.

The problem here is somehow a binary with the PSKEYS is loaded but that cause a failure in

the communication with the CSR wifi module (that is very similar to a issue Bluetooth module).

The only way to solved it is not loading that binary(firmware bin) or ask intel to provide a tested/working firmware binary.

Hi, Israel,

Thanks for your information.

I will try to follow your suggestion and tell if I have any result.

Hi, I'm having the same issue using a pcie card with Intel 6235 on an i.mx6 board with kernel 3.0.35.

Have you been able to solve this problem?

[israelpz]

Hi,

Seem to be a problem with the physical layer.

Are you using a PCI express module? Or is USB?

I ask because similar errors also appear on Bluetooth layer when the buadrate, parity or link layer are not setup

properly to the ones stored in the chip firmware then it will start to generate timeouts and also frame errors.

Do you have that information for that wifi module?

Regards,

-Israel

[toniehuang]

Hi, Israel,

Sorry for lately response.

What I used is PCI express modules.

And I didn't have any further information about that wifi module. (Intel doesn't release any doc to us)

All I have is those file from the opensource of Intel wifi module.
