Hello,

I have an AT91SAM3U-EK and the SAM-ICE JTAG programmer. I am using
YAGARTO along with the sample project I have attached. This is the
tutorial I am following

http://yagarto.de/howto/jlink/index.html

I am slightly confused about the programming procedure and how it works.

This is the GDB script that is included with the example project

#
# This config file was tested with J-Link GDB Server v4.10i
#

# connect to the J-Link gdb server
target remote localhost:2331

# Set gdb server to little endian
monitor endian little

# Set JTAG speed to 5 kHz
monitor speed 5

# Reset the target
monitor reset
monitor sleep 100

# Set JTAG speed in khz
monitor speed auto

# Vector table placed in RAM
monitor writeu32 0xE000ED08 = 0x20000000

load

monitor reg r13 = (0x20000000)
monitor reg pc = (0x20000004)

break ResetException
break main
continue

Rather than asking "what does this do" I would like to know where I need
to look to figure it out my self. I had to install the J-Link server
software along with all of the YAGARTO tools so I am not sure what
exactly is going on when I follow the directions, or what tools are
being used to do the programming, so I am not sure what documentation I
need to dig into. If anyone can tell me exactly what is going on here,
or point me to some good resources I would really appreciate it. I want
to be able to write my own GDB scripts and extend these techniques as
much as possible.
