Hello Joseph,
I am working on wl1805 integration with dm8168 processor. The kernel version is 2.6.37.
1) I am little confused with wl12xx and wl18xx. Are they both same or is there any difference between them?
-----------
2) I am trying to build the compat wireless for wl18xx from the procedure give in the below link
http://processors.wiki.ti.com/index.php/WL18xx_System_Build_Scripts
I have set the env file and calling the build script as ( sudo ./wl18xx_build.sh all )
I have run into the following error
Base tree: wl18xx.git

cornet@cornet:~/ti-ezsdk_dm816x-evm_5_05_02_00/build-utilites$
I have return the build command( sudo ./wl18xx_build.sh all ) output to a file and attaching it here.
I tried to edit the of.h but every time i compile the changes are gone and it shows me same error.
I edited the kernel source as told in this link
http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_OpenSource_EZSDK_WLAN_build
this procedure is for dm814x processer but i tried modify it for dm8168 processer. I still have to check this once i am able to compile the above utils with the build script.
Can you please help me with the above issue. Am i going in the correct path?
There are two build scripts 1) wl18xx_build.sh 2) wl12xx_build.sh. I am using first script. is that correct? or should i use the second script?
------------
3) In your previous message you told we can make wl18xx work with 2.6.37 kernel with some changes. Do you have any procedure which can help me?
Will be waiting for your reply. Thankq very much. please help.
Regards,
Srikanth.
Hi Srikanth,
(1) wl18xx_build.sh builds the WiLink8 drivers & wl12xx_build.sh builds the WiLink6/7 drivers. They are both different, and you should be using the wl18xx_build.sh script for your WL1805 integration.
(2) You can directly edit files in the "compat-wireless" package, and do a make inside the compat-wireless package.
(3) Like I told in my previous post, the minumum verified WL8 kernel version is 3.2 - older kernel versions might work, but you might have to modify the package. Unfortunately, I don't have any procedure for this.
Regards,
Gigi Joseph.
Hello Joseph,
Thank you very much for the reply.
I will try the steps and reply as soon as possible.

Hi Srikanth,
Please verify proper power up sequence of the module (VDD/VIO/CLOCK/ etc).
The power up sequence is mentioned in the data sheet as well as the below wiki page:
http://processors.wiki.ti.com/index.php/WL18xx_Module_Schematic_Checklist#Power-up_Sequence
Regards,
Gigi Joseph.
Hello Joseph,
In the power up sequence, it says we have to put "WLAN and BT_EN" to the gpio, We are not using the Bluetooth. do we have to enable that also.
I have a CD(Card detect resistor) connected. Do i have to remove that also?
Thanks for the help.
Regards,
Srikanth.

Please help.
Thanks,

Hi Srikanth,
Have you verified the Clock/connections?
I don't think this is a problem on the software side.
Regards,
Gigi Joseph.
Hello Joseph,
We checked the connections and trying to get the power up sequence right.
We are getting the WLAN_EN high and can see the clock when the commands are send out from the host. We are not getting the WLAN_IRQ.
http://processors.wiki.ti.com/index.php/WL18xx_Platform_Integration_Guide#WLAN_Reset.2FPower_up_sequence
The WLAN power-up sequence waveform in the above link before WLAN_IRQ high pulse it is told that "indicates completion of FW download and internal initilization". Can you tell us what dose that mean? Is the WL1835MOD download the FW from the host or the FW is stored in the module already?
Is the host have to download any firmware to the WL1835?
When we are trying to find the techinical documents for the wl1835 register addresses or any information we are unable to get them. Where can we get them? Can you provide us the reference manual for the WL1835 and WL1805?
Thanks for the help.
Regards,
Srikanth.
Hi Srikanth,
The host has to download the fw.
This will be taken care by the wl18xx driver itself. You just have to ensure that the correct fw (a file named wl18xx-fw-4.bin) is available in "/lib/firmware/ti-connectivity"
But I think your problem happens much earlier... The SD init is failing in your case.
Regarding the wl18xx register address, the driver source code is open. You can take a look at: "reg.h" (drivers/net/wireless/ti/wl18xx/)
Regards,
Gigi Joseph.
Hello Joseph,
Thanks for the help.
The problem is with the hardwarw connections.
The basic commands of the SD is clocked at 400khz and when the SDIO negotiate with the wl1835 and tries to swith to 50Mhz clock then it fails with -110 error.
Our hardware engineer is trying to shot the wire length, to make it work.
We are not sure if the wl1835MOD which we have is working, so we purchased a AM3359 evm board and tried to check it.
We have used "AM335xSDK 06_00_00_00" SDK.
We used the link below to get the wl18xx compilation.
http://processors.wiki.ti.com/index.php/WL18xx_System_Build_Scripts#Building_R8.3_SP1
It compiled and the board booted fine loading the wl18xx modules and firmware.
we are able to see the wlan0. and doing down and up on the device is also fine. when we tried run the command "iw wlan0 scan" it crashes with the messages below.

Can you please tell us if our wl1835mod is working. Is there any more test to make sure the module is fine?
Thanks,
Srikanth.
Hi Srikanth,
I think your module is working fine as you are able to turn on WLAN. The only problem is: "wlcore: ERROR ELP wakeup timeout!" while scanning.
The typical reason for this would be the mapping of the IRQ line in your host.
Since you have an AM335x, I recommend that you use the prebuilt binaries in: http://processors.wiki.ti.com/index.php/WL18xx_AMxxx_platform_integration_guide
and confirm the WLAN functionality.

Gigi Joseph.
Hello Joseph,
Sorry for the late reply.
We purchased a new wl1835 dongle and checked it with the AM3359 board and it is working fine.
The previous dongle which we have is gone bad.
One more good news is, i told you that we are making a custom board with dm8168 processor and put wl1805 chip in that. we received the board last week and after all the board bring up and video working. We put the wifi code which you helped us with and it worked very well. Now we are able to stream the video through wifi.
We really appreciate your help. Thanks a lot.
Regards,
Srikanth.
Hi Srikanth,
Thanks for the update... I will mark this as closed.
Please raise a new thread for any additional assistance.

Hello Kunjal,
I am using the SDK version "5_05_02_00" and the kernel is 2.6.37.
My wifi driver version is "R8_A6_02" and when my board boots up it says "wl18xx driver version: R8.xx_Build-309"
Joseph has provided us with the build scrips which helped us to bownload the backport and build for 2.6.37 kernel.
Thanks,
Srikanth.
