FXAS2100X Gyro iMX6 Linux IIO driver

bdp42 — Wed, 18 Oct 2017 17:02:36 GMT

I'm looking for a Linux driver for the Freescale Gyro FXAS2100X, for an iMX6 based platform. I've looked at number of Freescale kernels and there does not seem to be one for this device that follows the IIO model. There is one in "drivers/misc" but it is follows the older model. There are a number of IIO drivers for other Freescale sensors but not for this particular gyro.

Is there a particular reason for this?

Thanks

Bruno

Hi Bruno

usually drivers provided for chips used in nxp reference boards, for

i.MX6 based board drivers one can look at Linux Manual included in doc package

https://www.nxp.com/webapp/Download?colCode=L4.9.11_1.0.0_LINUX_DOCS

and try to develop own driver using existing as example. There is

NXP Professional Services helping with developing custom drivers

Thanks Igor.

I guess the real question I was asking was if Freescale/NXP are not supporting the FXAS2100X family as it seems strange that an IIO based driver has not been developed for this device but they have for other sensors. I've looked at the latest imx kernels and they all have the old style driver. for the FXAS gyro.
