The missed interrupts issue sounds likely. There are pins on the module that I do not have connected to the Beaglebone board. I wanted to run jumpers from the module to the P9 header on the Beaglebone. I can define gpios as input or output in the pinmux definition for mmc1, but I do not know how to get the driver to recognize these and use them. I tried grepping the brcmfmac source code for a clue, but I did not find any reference to any pin definitions. How do I associate these gpio lines with the driver? -----Original Message----- From: linux-omap-owner@xxxxxxxxxxxxxxx [mailto:linux-omap-owner@xxxxxxxxxxxxxxx] On Behalf Of Tony Lindgren Sent: Thursday, June 9, 2016 2:44 AM To: Michael Eskowitz <MichaelE@xxxxxxxxxxxxxxx> Cc: linux-omap@xxxxxxxxxxxxxxx Subject: Re: Bringing up the BRCM43362 on Beaglebone Black * Michael Eskowitz <MichaelE@xxxxxxxxxxxxxxx> [160608 13:46]: > Some progress, but I'm hoping that someone can give me a clue... > > I have set up the pins on mmc0 according to the TI pinmux tool and I > am following the example from the kernel documentation which shows how > to setup a node with properties controlling the Broadcom wireless > device.

Sounds like possibly 43362 driver bug maybe. Could be caused by spurious or missed interrupts. You may need to add the sdio dat1 remuxing to GPIO during idle using the pinctrl named states in your dts file.
