Have you asked over at the meta-freescale list? As you know, driver support is likely to be closely linked to the Linux kernel provided for the i.MX6, and they are in the best position over on that list to answer your question. Whilst I don't have a definitive answer for you if you look at the Freescale Embedded Linux bundle for the i.MX6 processor (e.g. L3.10.17_1.0.0_LINUX_DOCS <https://www.freescale.com/webapp/Download?colCode=L3.10.17_1.0.0_LINUX_DOCS&appType=license&location=null&fasp=1&WT_TYPE=Supporting%20Information&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=gz&WT_ASSET=Documentation&fileExt=.gz> ) you will see sections on GPIO, I2C, and FlexCAN. There are also details in those sections on the specific kernel configuration options that need to be turned on if they are not already turned on by default in the meta-freescale kernel configuration. If the drivers you need are not built into the standard kernel by default then you will need to make some configuration changes. To do so you might wish to start by looking at the Yocto kernel development manual here http://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html Incidentally. I haven't yet had a chance to pick up a copy of Otavio Salvador's book "Embedded Linux Development with Yocto Project" but he's active with all of this over on the meta-freescale list so you could probably do worse than take a look at his book. e.g. http://www.amazon.co.uk/Embedded-Linux-Development-Yocto-Project/dp/1783282339 Regards, Alex
