ODIN-W160 with i.MX6Q

[NithinkumarN]

Hi All,

I'm using ODIN-W160 Wi-Fi and BT combo module in my project.

i.MX6Q processor and Linux 3.10.17 kernel version.

I'm following back port driver method as given in below link

WL18xx Platform Integration Guide - Texas Instruments Wiki 

But when I'm booting my platform with image containing all these changes getting error like below.

root@iWave-G15M:~# mmc0: Timeout waiting for hardware interrupt.

wl1271_sdio mmc0:0001:2: sdio write failed (-110)
wlcore: ERROR couldn't get hw info

When I asked with module support, they told to check host side of i.MX6Q processor.

Please help me to figure out what is causing this problem.

Thanks and Regards,

Hello Nithin kumar N,

I don’t have experience with this wireless module. However, since TI mentioned that the software part was correct -which would include the kernel and driver version matching correctly- and due to the nature of the error you are seeing I would suspect it to be a problem with the device tree definition.

I see that the link you provided has the information to edit the device tree of several TI based boards. You would need to perform the necessary changes for your board based on these directions. There is even a Yocto layer for supporting this device but only on its own board.

https://github.com/u-blox/meta-ublox

My recommendation would be looking at the device tree changes you made as there was probably a conflict there. There is a simple document that shows how to edit the device tree although you probably already know the basics.

https://community.nxp.com/docs/DOC-329664

My apologies for the inconvenience.

Regards,
