This chapter describes the use of the Sourcery G++ Debug Sprite for remote debugging. The Sprite allows you to debug programs running on a bare board without an operating system. This chapter includes information about the debugging devices and boards supported by the Sprite for ARM EABI.
Table of Contents
Sourcery G++ Lite contains the
Sourcery G++ Debug Sprite for ARM EABI.
This Sprite is provided to allow debugging of programs running on a
bare board. You can use the Sprite to
debug a program when there is no operating system on the board, or
for debugging the operating system itself. If the board is running an
operating system, and you wish to debug a program running on that
OS, you should use the facilities provided by the OS itself (for
instance, using gdbserver
).
The Sprite acts as an interface between GDB and external debug devices and libraries. Refer to Section 6.3, “Invoking Sourcery G++ Debug Sprite” for information about the specific devices supported by this version of Sourcery G++ Lite.
The Sourcery G++ Debug Sprite is not part of the GNU Debugger and is not free or open-source software. You may use the Sourcery G++ Debug Sprite only with the GNU Debugger. You may not distribute the Sourcery G++ Debug Sprite to any third party.
Before running the Sourcery G++ Debug Sprite for the first time, or when
attaching new debug devices to your host system, it is helpful to
verify that the Sourcery G++ Debug Sprite recognizes your debug
hardware. From the command line, invoke the Sprite with the
-i
option:
> arm-none-eabi-sprite -i
This prints out a list of supported device types. For devices that can be autodetected, it additionally probes for and prints out a list of attached devices. For instance:
CodeSourcery ARM Debug Sprite (Sourcery G++ Lite 2010.09-51) armusb: [speed=<n:0-7>] ARMUSB (Stellaris) device armusb:///0B01000C - Stellaris Evaluation Board (0B01000C) rdi: (rdi-library=<file>&rdi-config=<file>) RDI Device rdi:/// - RDI Device
This shows that ARMUSB and RDI devices are supported. The exact set of supported devices depends on your host system and the version of Sourcery G++ you have installed; refer to Section 6.3, “Invoking Sourcery G++ Debug Sprite” for complete information.
Note that it may take several seconds for the Debug Sprite to probe for all types of supported devices.
