>RedBoot&#8482; is an acronym for "Red Hat Embedded Debug and Bootstrap",
and is the standard embedded system debug/bootstrap environment from Red Hat,
replacing the previous generation of debug firmware: CygMon and GDB
stubs. It provides a complete bootstrap environment for a range of embedded
operating systems, such as embedded Linux&#8482; and eCos&#8482;, and includes facilities
such as network downloading and debugging. It also provides a simple flash
file system for boot images.</P
><P
>RedBoot provides a wide set of tools for downloading and executing programs
on embedded target systems, as well as tools for manipulating the target system's
environment. It can be used for both product development (debug support) and
for end product deployment (flash and network booting).</P

>Although RedBoot is derived from eCos, it may be used as a generalized
system debug and bootstrap control software for any embedded system and any
operating system. For example, with appropriate additions, RedBoot could replace
the commonly used BIOS of PC (and certain other) architectures. Red Hat is
currently installing RedBoot on all embedded platforms as a standard practice,
and RedBoot is now generally included as part of all Red Hat Embedded Linux
and eCos ports. Users who specifically wish to use RedBoot with the eCos operating
system should refer to the <SPAN

of RedBoot in an eCos environment.</P
