10 Debugger
10.1 Features
The debugger gdb is software used to debug a program after loading an elf-format object file created by the linker.
This debugger has the following features and functions:
• Can reference various types of data at one time, thanks to a multi-window facility.
• In addition to debugging programs using the ICD Mini (S5U1C17001H) or ICD board, the debugger incorporates
• Capable of C source and assembly source level debugging.
• Supports C source and assembler level single-stepping functions, in addition to continuous program execution.
• Supports hardware and software PC break functions.
• Can measure program execution time by duration of time or number of cycles.
• Supports a trace function that allows saving of the traced data (in simulator mode).
• Can automatically execute commands using a command file.
• Supports a simulated I/O function that allows Stdin/Stdout evaluation in the debugger.
• Supports the embedded system simulator that allows evaluation of port input/output, SVD and LCD display in
• Supports the flash writer function of the ICD Mini (S5U1C17001H).
