2.5.1 Redhat Redboot
RedBoot* 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 bootstrap environment for a range of
embedded operating systems, such as embedded Linux and eCos*, and includes facilities such as
network downloading and debugging. It also provides a simple Flash file system for boot images.
RedBoot provides a 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).
Here are some highlights of RedBoot capabilities:
• Boot scripting support
• Simple command line interface for RedBoot configuration and management, accessible via
serial (terminal) or Ethernet (telnet) (see Section 2.6.4, “GNUPro GDB/Insight” on page 26)
• Integrated GDB stubs for connection to a host-based debugger (GBD/Insight) via serial or
Ethernet. (Ethernet connectivity is limited to local network only)
• Attribute Configuration - user control of aspects such as system time and date (when
applicable), default Flash image to boot from, default fail-safe image, static IP address, etc.
• Configurable and extensible, specifically adapted to the target environment
• Network bootstrap support including setup and download, via BOOTP, DHCP and TFTP
• X/Y-Modem support for image download via serial
• Power On Self Test
