0. Execute [RealView Debugger]

1. Connect target
[Target] -> [Connect to Target]
Select the the Arm architecture you are using.

2. Open executable file
[Target] -> [Load Image]
Select '*.axf'

3. Set break point (2 ways)
i) [View] -> [Symbols]
Find the symbol to set break-point and set break-point to it
ii) In the command window:
break jpgd_idct or
binstr S:0x00011B14

4. Run (F5)

-- Other Tips --
1. On RVCT 3.1 version, setting 'd' register by setreg command, like
setreg @d0=0x0000000000000034
makes wrong result.

2. command etc.
> reset
> load/r 'W:\SVN\jpg\app\jpgd_test.axf'
> break jpgd_idct
> go

$ fromelf -c file.o
This command is similar to objdump

Introduction

This manual documents how to use the GNU compilers, as well as their features and incompatibilities, and how to report bugs. It corresponds to the compilers (GCC) version 4.5.0. The internals of the GNU compilers, including how to port them to new targets and some information about how to write front ends for new languages, are documented in a separate manual. See Introduction.

+ Disable 'Enable support to enter complex characters' Option
System -> 관리 -> 언어 -> Input method
I don't know the exact reason, but we can't use keyboard in VirtualBox with this option. And I like the system font shown when this option was disabled.

Be careful, or your hearts will be weighed down with dissipation, drunkenness and the anxieties of life, and that day will close on you unexpectedly like a trap.

1. Need to prepare what you will say at first in each slide.
