> I see that [Eric's] nitrogen6x boundary tree has some devicetree patches to enable the TI Wi-Fi module. I am trying to bring it up on our custom board and I have a few questions:Where did you get the 'calibrate' utility? There are several repos out there for it.Did you just use the wlcore/wlcore_sdio/wl12xx drivers in the 3.10.17 kernel tree or did you pull anything from backports/compat-wireless/TI?Related, did you add the compat-wireless recipe to your image?
> I have BT working just fine but I am having issues bringing up the Wi-Fi side of the card. The first is getting it to calibrate:

> I have tried various combinations of drivers and tools but they all have the same error (command complete timeout). As a test I tried changing the <interrupts> node in the wlan section to <23 0x2> from IRQ_TYPE_LEVEL_HIGH and the error changes to timeout waiting for hardware interrupt so I know it is at least talking.

I probed the SD clock line and saw that it was running at 26Mhz not 38.4 so I tried changing it in the device tree but it still gets the same error.
