Wilink8 Platform data not set

Hi Sir,

             Thanks for reply. Sir i was working on mine .dts file before your this gentle reply and now i have corrected and now i have come out of above problem but trap into new problem. I think i am very near to mine success but something subtle is still missing which i am not able to figure out. Here i am again going to share mine partial dump of serial console , please have a look and guide me and i will be highlighting the relevant and problematic section as well  as per mine understanding and guide me to accomplish mine goal.

Hi,

Yes, you are much closer now. It seems like it is crashing now on an sdio access after the firmware was already loaded successfully. It could be hardware related to the SDIO bus lines configuration.

Can you try lowering the sdio bus speed for testing and see if it helps?
You can do that by adding:

max-frequency = <10000000>;

to the mmc node in your .dts file and it will limit the sdio speed to 10Mhz. if it still doesn't work try an even lower frequency.

In addition, you are not using the latest drivers/firmware. It would be better that you switch later on to the latest release which is (R8.7_SP1)

BR,
Eyal

Hi Sir,

            Thanks for such a quick and gentle reply. I will try it and let you know in next few minutes. By the way here i am attaching mine .dts file . Please have a look meanwhile and if anything wrong please tell me.

Regards

Aditya

Hi Sir,

           I tried your suggestion and gone till <1000000> but still i am not getting success. I more thing sir, I am using R8.5 because i am following

             website

            because this site is being managed by Avnet Silica for the Zedboard  and they have given the sequential steps for Integration of Wilink8 adaptor with Zedboard with kernel 3.17. As i am very new to this development that is why i thought that first let me at least get the Wilink8 1835 module to work properly with the provided steps, then i will try to upgrade with R8.7 mineself. Hope u understand this. So please help me to work it out with R8.5 now later on i will try with R8.7. Here i am again sharing mine dump please have a look and suggest me.

Hi Sir,
Much Thanks for your guidance . Mine above problem got solved. Only one thing is remaining.....when i am running the following command

iw wlan0 XZ10 1003

It is giving me o/p as follows;-

command failed: Invalid argument (-22)

What is reason for this???? (XZ10 1003 is mine mobile hotspot name)

Regards
ADITYA

Hi Sir,

Here is mine commands:-
1-ifconfig wlan0 up
wlcore: PHY firmware version: Rev 8.2.0.0.224
wlcore: firmware booted (Rev 8.9.0.0.31)
2-iw wlan0 scan | grep SSID
SSID: G604T_WIRELESS
SSID: XZ10 1003
SSID: MOBILE_LAB
SSID: ASUS
SSID: HP-Print-28-LaserJet Pro MFP
3-iw wlan0 connect XZ10 1003
So when i am typing above it is giving me error that i have mentioned in mine previous post.
But when i am typing
iw wlan0 connect XZ10-1003
Then it is showing no error But in this if type the following command
4-iw wlan0 link
Then it shows not connected.

Please suggest me some idea.

Regards
Aditya

Sir,

      Adding to above POST , also when i tried to connect MOBILE_LAB SSID ,i got the following thing:-

Hi again,

Seems all is working as expected on your side now.

Your issue is that using iw you can only connect to open AP (with no security configured).

For the ap with the SSID "XZ10 1003", in case it is an open AP (no security enabled) you should probably use:
iw wlan0 connect "XZ10 1003"
The space inside the AP SSID is your issue.

If you connect to a secure AP (WPA2 etc.) you need to use the wpa_supllicant.

In case you have the example scripts under:

/usr/share/wl18xx

You can use the following examples wiki:

processors.wiki.ti.com/.../WiLink8_WLAN_Demo:_Linux

In case you don't have it, you can use wpa_cli commands direcly. See the following wiki:

Hi Sir,
Thanks for such a pin point guidelines. It worked........ YES I am able to ping the unsecured networks and now i have to look that how to reach secured networks. Sir one thing when i tried to use the following command :
1- iw reg get.............then i got the below output
country 00: DFS-UNSET
(2402 - 2472 @ 40), (6, 20), (N/A)
(2457 - 2482 @ 40), (6, 20), (N/A), PASSIVE-SCAN
(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN
(5170 - 5250 @ 160), (6, 20), (N/A), PASSIVE-SCAN
(5250 - 5330 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
(5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
2- when i type the
iw reg set IN
then it is giving me the following msg:-
cfg80211: Calling CRDA to update world regulatory domain

and it is stuck at above line

So how to get out of this. I think if this done then we can access the secure networks also.
Please guide me.

Regards
Aditya

Hi Aditya,

Great you are able to ping!

What is not working for you now is not related directly to the wlan drivers but rather to the regulatory domain application in your file system.
You can still use WPA supplicant just that you are avilable to the channels listed above that are supported by the "world" regulatory domain which is a subset of the channels that are allowed all around.

do you have the "crda" utility installed in you file system?
What is the output you get if you execute the following from command line:
COUNTRY=IN crda

Best Regards,
Eyal

Hi Sir,
Thanks a lot . Without you i would not have completed this task. Right now i am looking into crda regulatory problem and i will update you accordingly.Please do not close this thread now. I will tell myself for it. Sir i do not think i have crda utility in mine system. By the way where to look for this crda?????and sir when i typed the command mentioned by u, it shows that.........crda: command not found... and now mine full system is booted so i do not want to compile mine kernel again. So even if i have to install the crda in mine running system on mine zedboard....then how to do that.Could u plz guide me.

Regards
Aditya

Have you used our build script for building all the related components that are on your file system, or have you taken a ready made one?
In case you use our build script , crda is built as part of it.

When using our build script, the crda code is fetched and built from:
git.ti.com/.../R8.7_SP1

but it is a standard linux userspace package, so you can get it from other sources also for your target.

BR,
Eyal

Hi sir,
Actualy i am using Xilinx-linux-3.17 and i followed your scripts but build mine kernel at mine own just i took necessary items like ti drivers, many patches etc from your build scripts/src folder and paste in mine kernel and complile it.But when i build mine kernel i have seen there is no crda folder. So can i copy the crda folder from inside the crda folder generated by your script and copy it in mine kernel . But where to copy it and build it.
One more question do i need mac80211.ko, cfg80211.ko modules also( As i have found it from www.google.co.in/webhp

Regards
Aditya

Adding to mine above post , just now found out that i have wpa-supplicant.conf file in the etc folder. So now next what should i do????

Regards
Aditya

the "outputs" directory of the build script contain a compressed version of the fs directory content in a file called fs_skeleton.tbz2.
Please make sure you extract the content the entire fs_skeleton.tar.tbz2 into your rootfs as the files are spread across multiple locations (libs, init scripts, config files, binaries) for all components (supplicant, crda, libnl etc.)
Can't really help you in case you are trying to selectively copy only part of the files.

BR,
Eyal

Hi Sir,
That is fine. So if i unzip this so it might possible that i will find a folder crda somewhere , then i will copy this in mine respective rootfs. But one thing ...dose this got any dependency on the kernel build???What i want to say that :- can i copy the crda folder directlly into mine rootfs without building mine kernel??? or do i need to build mine kernel with some special configuration???? Just give me your opinion if you have any idea abt this. Otherwise it is fine.
Meanwhile alsoi am looking into wpa_supplicant.conf file which is available in mine etc folder????It seems that this requires some simple configurations......and mine work will be done. I will update you.

Regards
Aditya

You can checks the build-utilites/fs folder. Everything is created in there before it is zipped into fs_skeleton.tbz2.
If you look there you should see crda as well under .../fs/sbin/crda
but there are other related files as well.
Same for all the relvant wpa_supplicant components/conf files

The only part that is dependent on the kernel is the kernel modules (.ko files) but you have copied this part already anyway, right?
Just copy/extract everything into your rootfs.

BR,

Hi,

    I just want to clarify something from you. I have got wpi_cli in mine board and i am trying to configure so that i connect it with secure APs. Still i tried to put crda in mine build but i think there is something missing and i got some errors that am working out. But mine question is this :-- whenever i am trying to connect to a AP it is calling one CRDA update regulatory domain agent..............so what is this doing and what for it looking. As crda is not in mine filesystem even then i am able to reach non secured as well as secured APs, though in the case of secured APs i am not able to establish the connection, but in both the cases i am getting the following msg on mine console

CRDA update regulatory domain agent..

1- So why crda is important to me????

2- I do not have crda in mine file system and now i do not have any issue but i want to know that :--in what case i will be needing this and why and what problem it may create if it is not there:- i.e which applications will be looking for this.

Regards

Aditya

Please check the following page regarding CRDA and what it is:

As I wrote before you can work without it but only a subsequent of the channels will be usable. Threre may be channels in India that will not be open to you unless you update your regulatory to IN.

If the AP you use is on one of the "World" channels and you can connect to it then you are ok for now.

BR,

Hi Sir,
Thanks for reply. So sir , right now i am planning to start without any crda kind of stuffs as it is working without it also. I will come to this issue again in later time and update you.
By the way sir i was exploring wpa_supplicant and i found that i have one wpa_supplicat.conf file in etc folder and its content is as follows:-

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
key_mgmt=NONE
}

So you suggested one webpage being managed by TI, if i want to worked with secured APs also , so as per this when i executed the very first command which is as below;-

/usr/sbin# wpa_supplicant -d -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0 -B

to run the web_supplicant as a Daemon process in background. It gave me the following error

-sh: /usr/sbin#: No such file or directory

could u plz tell me what is the missing thing here??
Also sir is there any app here on TI e2e community so that i chat with u online............

Regards
Aditya

Hi Sir,
i found the mistake . Actually in the above # is wrong.

Hi Sir,

           I want to know one thing. When i run the command "wpa_supplicant -d -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0 -B", i found something very strange. Here is mine dump. In this i will be making the lines BOLD about which i want to ask something. First plz have a look :--

So i want to know that :- i have done nothing(CRDA is not installed till now)  but when i called the daemon process by that command how it has automatically called "Calling CRDA for country: IN".

That is how it knows that it has to call country code IN ?????? I have not given nay country code before running that command.

Could you explain the above process.

 

Regards

Aditya

 

Hi Sir,

           Everything is working fine . I am able to connect with secured IPs by following the scripts on that web page. I did one change in mine wpa_supplicant.conf file and i added "country=IN". Then this time when i called daemon process , it did not not display the following line ,which you can observe in mine previous post.

wlan0: deauthenticating from e8:ba:70:c2:44:32 by local choice (Reason: 2=PREV_AUTH_NOT_VALID)

Sir i want to discuss something for mine own curiosity .

After connection with secured IP when i called "iw reg get" then it is showing:-

country 00: DFS-UNSET

       (2402 - 2472 @ 40), (6, 20), (N/A)

       (2457 - 2482 @ 40), (6, 20), (N/A), PASSIVE-SCAN

       (2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN

       (5170 - 5250 @ 160), (6, 20), (N/A), PASSIVE-SCAN

       (5250 - 5330 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN

       (5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN

Then i called 

iw reg set IN

This time it displays 

cfg80211: Calling CRDA to update world regulatory domain

Q.1-  When i do not have crda in mine kernel then who is calling this and why???Nothing is there to updat???? So as per mine understanding this iw is calling crda to update some database as i have used the command "set iw reg set IN"...............Am i right????

After this now i typed the folowing command:-

iw reg get

an its result is following

country 00: DFS-UNSET
(2402 - 2472 @ 40), (6, 20), (N/A)
(2457 - 2482 @ 40), (6, 20), (N/A), PASSIVE-SCAN
(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN
(5170 - 5250 @ 160), (6, 20), (N/A), PASSIVE-SCAN
(5250 - 5330 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
(5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN

Q.2- If i am right as per mine observation then when i executed the command "iw reg get" now,  then it should have showed me country IN but it is showing the default. This means that there is no regulatory update, which has been indicated by above in mine Q.1

Q3. According to mine observation in Q.2, then there is no meaning of setting country=IN in wpa_supplicant.conf file.

Sir, plz could u explain what is going on. Though mine system is working but i want to know just becoz of mine curiosity.

Regards

Aditya

Hi,

The mac80211 layer in the kernel is triggering the call to crda. However as you don't have it nothing happens...:

cfg80211: Calling CRDA to update world regulatory domain

In case you had crda installed correctly you should have seen additional messages like:

Hi Sir,
Thnaks for reply. I understood what u want to say. I will work on crda and update u later time. Sir is there any document or webpage that tells about the complete capability of this Wilink8 module which talks about its various configuration and network modes. Can we make this Wilink8 module as a AP for the other devices in the network(It must be there.....). So regarding all this could u please suggest me something???
Actually i would like to work on some kind of IoT application where i want to make module as a AP and other devices to connect with it.

Regards
Aditya

PS , In mine previous post , it is typo mistake and i wrote Thnaks.
Plz read it as ,Thanks .

Regards
Aditya

Yes, AP mode is supported of course.
See the following usefull wiki page:

Hi Sir,

          i am able to successfully transfer the some file.txt ,which is of few KB, from mine Ubuntu PC to the Zedboard attached with Wifi module and i have used  tftp command. But moment i tried to transfer a boot.bin (4 MB). Something wrong happened for which i am dumping mine console data here. Plz have a look and suggest me something. I am doubting on two things:-

1- either , there is issue in mine device tree at the place where i have defined reg varibable. As currently the value of reg =<0x0e010000 0x1000> .So mine doubt is that the value 0x1000 is less for 4MB file?????

2- or i am using the command 

tftp -g -r boot.bin 10.10.2.2...........

So, is tftp not understanding the .bin format???? because when i used the same command to get the .txt file(few KB) , then it was fine but when i used the command to get the .bin file then some problem occured.

Here is mine dump while doing tftp for 4mb boot.bin file.

tftp -g -r boot.bin 10.10.2.2
