This page is meant to serve as a quickstart guide that takes you from opening an Overo + Expansion out of the Box up to Remote Debugging with Eclipse on Ubuntu.

== Setting up Minicom ==
# sudo apt-get install minicom
# sudo minicom -s
# [Serial port setup] -> A - Serial Device -> /dev/ttyUSB0 -> [enter]
# [Serial port setup] -> F - Hardware Flow Control -> NO -> [enter]
# [Modem and dialing] -> A - Init String -> [empty] -> [enter]
# [Modem and dialing] -> B - Reset String -> [empty] -> [enter]
# [Modem and dialing] -> K - Hang-up String -> [empty] -> [enter]
# [Save as dfl]
# [Exit from Minicom]

== Power & Boot ==
# Plug the gumstix into the expansion board
# Plug the expansion board into your ethernet router / switch / whatever
# Plug in the micro-SD
# Plug a mini-usb plug (as you would use with a camera) into the mini-usb port labeled console
# sudo minicom -o # disables modem and dialing settings
# Plug in the 5v power supply
# Watch the system boot

== OpenEmbedded [OE] Toolchain on Ubuntu ==
[http://www.gumstix.net/Setup-and-Programming/view/Overo-Setup-and-Programming/Setting-up-a-build-environment/111.html Official (and Thorough) Documentation]

sudo apt-get install git-core
cd
mkdir -p ~/overo-oe/user.collection
cd ~/overo-oe
git clone git://gitorious.org/gumstix-oe/mainline.git org.openembedded.dev
cd org.openembedded.dev
git checkout --track -b overo origin/overo
cd ~/overo-oe
git clone git://git.openembedded.net/bitbake bitbake # just try this again if it hangs up
cd bitbake
git checkout 1.8.18
cd ~/overo-oe
cp -r org.openembedded.dev/contrib/gumstix/build .
cp ~/.bashrc ~/bashrc.bak
cat ~/overo-oe/build/profile >> ~/.bashrc
source ~/overo-oe/build/profile

The important part:
bitbake gdb-cross

== Gumstix Setup ==
From the previous step your Gumstix should have started configuring itself and hopefully is done, leaving you at the login prompt
root
passwd #(change your password)
ifconfig # configure as necessary. I assume that your IP address is 192.168.1.150
opkg install gdbserver

== Hello World! ==
This is all taking place on the Ubuntu system (192.18.1.100)

=== hello.c ===
mkdir ~/overo-oe/Code/
cd ~/overo-oe/Code/
vim hello.c

#include <cstdio>

int main(int argc, char ** argv) {
printf("Hello World!\n");
}

=== Makefile ===
vim Makefile

CGTOOLS = ~/overo-oe/tmp/cross/armv7a

# Compiler and Linker flags
C_FLAGS += -Wall -g
CPP_FLAGS += -Iinclude
LD_FLAGS += -g -lm

# compiler
CC = $(CGTOOLS)/bin/arm-angstrom-linux-gnueabi-g++ $(C_FLAGS) $(CPP_FLAGS) -c
LINK = $(CGTOOLS)/bin/arm-angstrom-linux-gnueabi-g++ $(LD_FLAGS)
STRIP = $(CGTOOLS)/bin/arm-angstrom-linux-gnueabi-strip

.PHONY: all clean
all: clean hello
clean:
rm hello *.o -rf
hello: hello.o
$(LINK) -o hello hello.o
cp hello hello.debug
$(STRIP) hello
hello.o: hello.c
$(CC) -o hello.o hello.c

=== Compile ===
Now we'll compile the program with the debug symbols, strip the symbols, and copy it to the gumstix (192.168.1.150)

make
cp ./hello ./hello.debug
~/overo-oe/tmp/cross/armv7a/bin/arm-angstrom-linux-gnueabi-strip ./hello

./hello # fails because it can't run on your architecture
ssh-copy-id root@192.168.1.150
scp ./hello root@192.168.1.150:/hello #
ssh root@192.168.1.150 "/hello" # succeeds
ssh root@192.168.1.150 "gdbserver 192.168.1.100:43276 /hello" # starts remote gdb
# use ctrl-z and then bg 1 to background this process, or run it from another ssh session
~/overo-oe/tmp/cross/armv7a/bin/arm-angstrom-linux-gnueabi-gdb --symbols ./hello.debug
target remote 192.168.1.150:43276
continue

=== Debug ===
Now we can introduce a bug and test again
mkdir ~/overo-oe/Code/
cd ~/overo-oe/Code/
vim hello.c

#include <cstdio>

int main(int argc, char ** argv) {
printf("Hello World!\n");
char * h;
delete h;
delete h;
}

== Eclipse ==
We explore how to use eclipse.

I'm currently grokking through
http://old.nabble.com/Solution:-Using-Eclipse-CDT-for-Gusmtix-development-tt18251552.html#a18251552
and
http://krupets.com/index.php?option=com_content&view=article&id=18&Itemid=20

=== Plugins ===
Update sites and plugins

=== Configuration ===
Navigating through menus

=== Remote Deployment Debugging ===
Having it somehow all come together to this culminating point
