This process includes a variety of activities +including the following: + +@itemize @bullet + +@item targeting the GNU development tools + +@item porting the RTEMS executive code + +@item developing a Board Support Package + +@item writing an RTEMS CPU Supplement manual for the completed port. + +@end itemize + +This document focuses on the process of actually porting the RTEMS +executive code proper. Each of the data structures, routines, and macro +definitions required of a port of RTEMS is described in this document. + +Porting any operating system, including RTEMS, requires knowledge of the +operating system, target CPU architecture, and debug environment. It is +very desirable to have a CPU simulator or hardware emulator when debugging +the port. This manual assumes that the user is familiar with building and +using RTEMS, the C programming language, and the target CPU architecture. +It is desirable to be familiar with the assembly language for the target +CPU family but since only a limited amount of assembly is required to port +RTEMS. + |
