Hi There,
I'm working on adding support for Wifi and BT (WL1835MOD) on our SabreSD-like board running Linux 3.10.17. I found promising-looking patches here
http://e2e.ti.com/support/wireless_connectivity/f/307/t/361507
However, it appears the patches are to be applied after another set of patches, because its referencing 0001-Add-DT-support-for-wilink-8.patch in the linux-imx_3.10.17.bb recipe, which I do not have.
Any ideas on where to find this ?
Thanks,
/Otto
btw, we are using the imx_3.10.17_1.0.0_ga version
Hi Sundeep,
Thanks for the quick response, however I cant make sense of the bluetooth-patch I mentioned in the original post.

This patch uses appears to be applied to the same version I'm using (imx_3.10.17_1.0.0_ga) and created after this version was released (Released May 2014), yet you say the 3.10.17 version already has support for the Wilink DT ?
Another customer had the same problem, but unfortunately the TI rep chose to send a personal email instead of sharing the solution with everybody -
Any help is appreciated,
/Otto
Hi Sundeep !
Not sure what you need. Email ID ? Is that something TI uses on the forums ?
Thanks,
/Otto
Hi Iain,
If the build is from the latest release R8.5, the patches we applied for ST_KIM and other sections are proper then what would be the other possibilities for getting a timeout.
From the LA captures the RTS and CTS lines are proper with both the signals pulled low signifying that communication channel is open.
thanks,
Hi Siva,
I think the debug for this is a hw investigation first. My understanding of your problem statement is that when WL_EN is driven high the 1.8V power rail is raised to 2.5V.
All the IO's on WL18xx are 1.8V so that should not be driving this voltage. So initial thoughts are that you have either a pull up somewhere around the WL18xx to a different 3.15V rail or you are driving 3.15V from WL_EN. Finding the source of this is the first step.

Hi Siva,
That is something you will definitely need to ask Freescale about. We have no idea how they have designed the MMC to be used.

Hi lain,
below reply i got from freescale persons.
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
The Linux OS contains an SD / MMC bus driver which implements the
SD / MMC bus protocols. SDIO card functionality (say, Wi-Fi) requires
additional specific driver. Manufacturers provide it, if there is no standard
Linux support.
Thank you for your interest in Freescale Semiconductor products and for the opportunity to serve you.
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Please tell our WIFI MODULE have any specific driver is there?
meanwhile i have asked the same doubt which i asked previously to you.
Thanks,
Sivakumar.
