How to add WILC1000 SDIO driver into WP7702 and test?

How to add WILC1000 SDIO driver into WP7702 and test? I have built the driver into WP7702, root@swi-mdm9x28-wp:/# lsmod
Not tainted
wilc_sdio 131217 0 - Live 0xbf1b5000
cfg80211 253977 1 wilc_sdio, Live 0xbf10f000.
But I couldnt find wlan under ifconfig? How to enumerate it and Test?

Hi Gokulnath,

Is there any solution to the issue faced here. I ran into a similar issue with WP7609 (MangOH green board with WILC1000) .

@asyal, anyone you could recommend that may be able to assist here? @arvindhrajthirumurth is looking to use the same part on the WP7609.

Good afternoon @arvindhrajthirumurth ,

There are a number of elements here that could be a factor. There seems to be a concerning matter of sensitivity when designing SDIO WiFi which in itself has various hardware and software aspects. As a first step, kernel logs would be a starting point and then there is also the question around the SDIO data trace and the importance of the trace lengths and widths. So just from this, determining the root cause is particularly complex as there are various vendors (HW and SW) in this equation.

My suggestion to you would be to consider the WiFi solutions that have been used on the mangOH Red or mangOH Yellow platforms. The design resources are publicly available for the components used here and here . In addition, there are WiFi solutions from Sierra Wireless partners that is shown in the IoT Card section of the website. Those partners would be in a position to support the solutions they have developed and are marketing.

As I entered the forum today to respond, I’ve noticed a few posts / threads that may be of interest:
