Got firmware panic while loading ti wl12xx module on imx6

Hi Subhaprada,

Your driver/firmware versions are out of date. Please update to the latest and retest.

Latest version: "ol_R5.SP7.01"
WL12xx build process: http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions

Regards,
Gigi Joseph.

Hi Joseph,

Thanks for your valuable reply.

But from Where should I get the driver that you mentioned.

I need that link to get it.

Thanks,

Subhaprada

Hi Subhaprada,

Please check the Build Instruction link at: http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions
This explains from where you can get the release also...

Regards,
Gigi Joseph.

Sorry Joseph.

Still am unable to find out driver and firmware for that release .

Can you please share the link with me so that I will take out the driver directly to download.

Regards,

Subhaprada

Hi Joseph,

I got the link to get the firmware and driver source required for my testing.

Thanks,

Subhaprada

Hi Joseph,

can you please suggest me which firmware version should i use for the driver version you mentioned.

Regards,

Subhaprada

Hi Subhaprada,

If you follow the build script at: https://github.com/TI-ECS/build-utilites/blob/master/wl12xx_build.sh , the script will ensure to download the correct fw version.

The correct fw version for ol_R5.SP7.01 is: Rev 6.3.10.0.139

Gigi Joseph.

Hi,

After doing modprobe i am getting following eror.

root@freescale /home$ modprobe wl12xx_sdio

wl1271_sdio: probe of mmc1:0001:1 failed with error -110
wl1271_sdio: probe of mmc1:0001:2 failed with error -84

Can you suggest me for this issue.

Thanks,

Subhaprada

Hi Subhaprada,

Can you share the complete boot logs?

Regards,
Gigi Joseph.

Hi Joseph,

http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions

This is taking the driver of its own and also firmware of its own.

Finally giving the .ko for wifi.

I am not able to select my driver using this link.

Can u please suggesthow I will select my driver and firmware for my progress.

Thanks,

Hi,

Can anybody will suggest me how can i compile my wl12xx wifi driver and will it take firmware of its own or how i will take the firmware for it.

I need the compilation process for my own wifi driver and also want the firmware needed for it.

My driver version is mentioned in this mail loop before.

Please find it.

Thanks,

Subhaprada Panda

Hi Subhaprada,

The below error:

wl12xx: firmware booted in PLT mode (Rev 6.3.10.0.136)
wl12xx: ERROR command execute failure 2

is because your driver and firmware are not matching.

Please note that each driver release will have its corresponding firmware release. So you cannot take an old driver code, and use it with the latest firmware...

Like I said before, R4_SP2_03_00 is a very old release. When you upgrade, please upgrade both the driver and the firmware to the latest release (git tag: ol_R5.SP7.01).

Regards,
Gigi Joseph.

Hi Joseph,

Thanks for your suggestions.

But I want to know the compilation process for driver and firmware.

I did not get from "NLCP build instrctions" about build procudure.

If you will post that then I will be grateful  to you.

Thanks,

Subhaprada

Hi Subhaprada,

Still not clear what you are looking for...

The "NLCP build instructions" page talks about the WLAN build script available at (git://github.com/TI-ECS/build-utilites.git). Download it, and make a setup-env based on your platform (also explained in the wiki page) and run "./wl12xx_build.sh all". 

You don't build the FW as it is available only as binary - the script takes care of downloading the correct fw binary based on the git tag in the build script.

Regards,
Gigi Joseph.

Hi Joseph,

Can you give me the link from where I will get latest driver and firmware for the wifi.

Thanks,

Subhaprada

Hi Subhaprada,

In the wl12xx_build.sh script, please modify

declare -A gen_tag="ol_R5.SP5.01"
to
declare -A gen_tag="ol_R5.SP7.01"
to download and build the latest Wifi driver/firmware.

As you know, the NLCP driver code is open source and available at: git://github.com/TI-OpenLink
While downloading from the git, you have to give the correct version tag. The build script takes care of all this.

Regards,
Gigi Joseph.

Hi Joseph,

How can I build my driver and how i will link the path to my driver so that build script will run my driver and will take the firmware required for it.

Thanks,

Subhaprada

Hi Subhaprada,

Can you please tell me what is your driver?
Do you mean you have modified the driver code and want to build it? You can integrate your changes to the latest driver and then do the build....

Regards,
Gigi Joseph.

Hi Joseph,

As you told I took the latest driver and firmware.

Build procedure was successful but I got below error while running the wifi driver script.

Here it is loading all the four ko modules.

Below is the error for your reference.

Please reply me to resolve this issue.

Hi joseph

hi joseph,

after taking the latest driver and firmware am getting below error.

Hi Joseph,

I hope nvs file size generated is 1113 but expecting was 912.

what should I do for that.

Thanks,

Subhaprada

Hi Joseph,

waiting for your valuable reply to resolve above issue.

Thanks,

Subhaprada

Hi Subhaprada,

Please generate a new nvs file, based on the below link:
http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Calibration_Proccess

and see if it helps.

Hi  Joseph,

MY wifi is working for first time only.

if i will make network down and then making up that time it is unable to work.

Actually i want to add my board file to the existing driver (compat-wireless)
 what I downloaded and build through script earlier.

Now how can i add my board file and config file in the script to work for my target imx6 freescale board.

Need your help.

Thanks,

Subhaprada

Hi Subhaprada,

[Q] MY wifi is working for first time only.
if i will make network down and then making up that time it is unable to work.

[A] Please refer to http://e2e.ti.com/support/wireless_connectivity/f/307/t/181835.aspx - it deals with a similar issue.
Basically, please ensure if WLAN_EN is disabled and enabled correctly.

[Q] Actually i want to add my board file to the existing driver (compat-wireless)
what I downloaded and build through script earlier.
Now how can i add my board file and config file in the script to work for my target imx6 freescale board.

[A] Not sure I understood the question. What did you give for KLIB_BUILD in the setup-env script? It should be the path to your linux kernel

Gigi Joseph.
