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
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
