Is there a good reason to stick to 3.14? If not, better use 4.4. If however there is a good reason, double check it is really good. Usually you don't want to use the Freescale vendor kernel but a vanilla kernel. Usually the latter has much better quality and the i.MX6 support is also good. > The WIKI [1] mention that we need to make sure that the RT-Preempt > version fits the kernel version we intend to use.

It might work, but you probably have to resolve some conflicts. And given there is a 3.14.62 you shouldn't use 3.14.52 any more. > - Must I need to patch the kernel to 3.14.61 and use the latest RT > patch release by Steve [3] some days ago?
