hey brother,
[Xenomai] Trying to install Xenomai 3.0.3 on i.MX6 Kernel 4.1.15
My situation is very similar to this man, Linux-4.1.15 and ipipe-core-4.1.18-arm-8.patch(Index of /downloads/ipipe/v4.x/arm/older ) not fully adapted, I solved the error and also compile successfully, but the system starts to become very strange , Will be blocked, I need to use external devices such as touch screen or mouse will continue to enter the system. Then I found that the contents of the diff in kernel_root / arch / arm / mach-imx / gpc.c and ipipe-core-4.1.18-arm-8.patch are very different.
there are three related files in the attachment, How to modify, thank you very much.
