The error I'm seeing now is due to a missing '.m' header file. The error looks like this ... ========= ../../freebsd/sys/arm/ti/am335x/tda19988.c:56:10: fatal error: rtems/bsd/local/iicbus_if.h: No such file or directory #include <rtems/bsd/local/iicbus_if.h> ========= There's an iicbus_if.m file in the freebsd source which is being included as ``#include "iicbus_if.h"`` How to work with the .m files ?
