We are woking on our coustom board with reference of DAVINCI
DM6446 board, In our board we included jorjin chip WG7310-00 , Now we
have a module to connect the (jorjin wg7310 module) on DAVINCI dm6446
reference board. From first on words we are trying to build code given
by jorjin for building wlan drivers that code also belongs to OMAP.
Now we are using linux-3.0 downloaded from net and ,we are using
that code to port wl1271 chip. upto now the interface is enabled and we
are able to see "wlan#" in /proc/net/wireless ( in our board file
After this we tried to do this "ifconfig wlan# up" but when we do this all this steps are taking place,
1. loading the firmware
2. going to boot firmware , when this step is going it is failing in "reading chip id "
it is getting stop at last it is giving this following messages
unsupported chip id: 0x1firmware boot failed despite 3 retriesmac80211 stopSIOCSIFFLAGS: No such device
and also i am noting this SDIO_CLK ,instead of 24MHz we are gving
8MHz . because we tried on all the clocks only on 8MHz it loading the
firmware.if not it is not able to load the firmware also .
Thanks and regards,
Y V RAMAKRISHNA.
We are waiting for your response . So,please respond us as soon as possible.
As far as I understand the SDIO is working with 1Mhz clock, so it implies that there is no Software and porting issues and the issue that we are facing now is hardware related and probably caused by signal integrity of the SDIO lines.
In that case we will not able to provide more help as it is beyond what we can support in e2e.
However in order to help you more I can give you some general guide lines: the SDIO lines should be shorter then 10cm, and noise free, also in case you are using level shiffter chip then extra attention must be taken for the layout. You can also consult the following document:
I hope that it will be helpfull,
Hi Eyal ,

I was out of the office till today, so I couldn't see your question. Please, send me all procedures you've already tried in order to see how to help you.
We are able to wake up the WIFI driver using "ifconfig wlan0 up" and scan for the wireless devices "iwlist wlan0 scan" .up to now it is Known.but from here what is the procedure to connect to some wireless device .i am not able to get.please help. on how to configure and connect our board wireless device with other wlan.
Thanks and regards ,

The next steps to connect to some AP is:
iw wlan0 scan | grep SSID - scanning for surrounding APs, grep is just for convinience
iw wlan0 connect AP_flour1 - connected to one of found APs, this is name for example. Whait for a couple of seconds the device takes to connect.
iw wlan0 link - to ensure that wlan device is connected to an AP
wlan0 is name of interface
Hope it will help,
in the same way we done with other commands ,because we are not have this "iw" command any have we are looking to download and install.
We done like this after it is wlan0 up :
1. iwlist wlan0 scanning
by giving the above command we got so many ssid's in that we selected one "Daximac"
2.iwconfig wlan0 essid "Daximac"
by giving the above command we are able to associate with that essid.
3.we are manually giving ip address using "ifconfig wlan0 xx.xx.xx.xx"
4.after this we are pinging to an ip address using "ping xx.xx.xx.xx" it is ping for 10 minutes and then getting disconnected.
before this we got beacon loss error for that we increased the time delay.after that we are able to do all the above .
how to make this a longer connection.
