Hello,
I tried to compile linux kernel 3.18.12 with xenomai 2.6.4 and rtserial
enabled on arm imx6. The compilation failed with :
CC [M] drivers/xenomai/serial/rt_imx_uart.o
drivers/xenomai/serial/rt_imx_uart.c:39:27: fatal error:
mach/hardware.h: No such file or directory
#include <mach/hardware.h>
^
I can see in the file :
#include <mach/hardware.h>
#include <mach/imx-uart.h>
The requested file seem to be in arch/arm/mach-imx/hardware.h and
imx-uart.h in arch/arm/include/debug/imx-uart.h so i tried to correct
the path with :
#include <../mach-imx/hardware.h>
#include <debug/imx-uart.h>
The compilation failed with :

Do you have an idea ?
