Trouble with USB WLAN driver on IPNC DM368

Do you see any error after connecting the wifi device to DM368 ? Please provide the output of

1. cat /proc/driver/musb_hdrc

2. enable debug messages $ echo D8 > /proc/driver/musb_hdrc and send us the log.

Reagrds,

Ajay

Hi Ajay,

Thank for you replying.

After loading the module, I looked for directory /proc/driver/musb_hdrc. But it doesn't exist.

Is there something wrong?

This is IPNC kernel message:

you need to enable "debug" at USB support -> Inventra -> Enable debug for proc entries.

Hi Ajay,

There isn't any settings like that. 

I followed your answers at USB mouse for DM6446. And I set the log level to 1.

Please check the following logs:

Thanks.

DEVCTL is -0x90 showing the controller is in device mode (D7=1) so can you confirm if you are using mini-A plug or jumper as proper place (ID pin jumper grounded) to connect the device to DM368 ? please note that mini-A is different than mini-B.

Regards,
Ajay

Hi Ajay,

I think I plugged jumper at proper place.

I found that Mode=Peripheral is wrong and it should be Mode=Host .

So, I change kernel setting at Device driver > USB support > [*]USB device filesystem and Device driver > USB support > Davinci 644x USB support > Driver Mode (USB Host)

After I rebuild kernel ,restart IPNCamera, load rt73 module and plug USB wifi. I got the the following message logs:

I think that IPNC detected USB wifi. 

Is there something wrong?

I also try to install Wlan USB WL 167g Asus driver into DM368 IPNC camera. I am using rt2570-cvs-2009041204. When I plug my device to camera I got message as below:

usb 1-1: new high speed USB device using musb_hdrc and address 6

usb 1-1: configuration #1 chosen from 1 choice

rt2570: idVendor = 0xb05, idProduct = 0x1706

rt2570: using permanent MAC addr

rt2570: Active MAC addr: 00:17:31:eb:95:64.

but I still can not see the wlan device in /dev and ifconfig didn't show any specific information for Wlan device.

Please help me!

thanks

These messages shows that device is detected successfully and also the control is given to WLAN driver. Now it's responsibility of WLAN driver and other componen if needed to create ifconfig node. Please check with WLAN manual/datasheet if you need to add some other driver?

ajay

Thank for your replying. It helped me a lot.

I changed to use driver rt2570 and it detected usb wifi successfully. 

Now I can config new device (ifconfig, iwlist, iwconfig,...). It detected my Wireless Access Point  successfully but it could't connect to AP.

----------------------------------------------------------------

ifconfig rausb0 up --> OK

iwconfig rausb0 mode managed --> OK

iwlist rausb0 scanning --> detected AP successfully

iwconfig rausb0 essid "my_ap"  --> cannot connect to AP (ping failed)

config static ip

-----------------------------------------------------------------

Does anyone have this case before?

Does IPNC DM368 support USB wifi?

What type wifi does IPNC DM368 support ?
