7 | The purpose of this manual is to provide a roadmap to those people porting |
---|
8 | RTEMS to a new CPU family. This process includes a variety of activities |
---|
9 | including the following: |
---|
10 | |
---|
11 | - targeting the GNU development tools |
---|
12 | |
---|
13 | - porting the RTEMS executive code |
---|
14 | |
---|
15 | - developing a Board Support Package |
---|
16 | |
---|
17 | - writing an RTEMS CPU Supplement manual for the completed port. |
---|
18 | |
---|
19 | This document focuses on the process of actually porting the RTEMS |
---|
20 | executive code proper. Each of the data structures, routines, and macro |
---|
21 | definitions required of a port of RTEMS is described in this document. |
---|
22 | |
---|
23 | Porting any operating system, including RTEMS, requires knowledge of the |
---|
24 | operating system, target CPU architecture, and debug environment. It is |
---|
25 | very desirable to have a CPU simulator or hardware emulator when debugging |
---|
26 | the port. This manual assumes that the user is familiar with building and |
---|
27 | using RTEMS, the C programming language, and the target CPU architecture. |
---|
28 | It is desirable to be familiar with the assembly language for the target |
---|
29 | CPU family but since only a limited amount of assembly is required to port |
---|
30 | RTEMS. |
