Devtool is a build framework to make cross-platform baremetal development simple across a variety of devices. It uses a combination of GNU make, Python and kconfig.

Devtool has relatively few dependencies which you should install or have installed:

• build-essential (gcc, make, and friends)
• libncurses-dev
• python

You'll also need git to obtain the source.

• Pollux/LF1000
  • Augen e-go
  • LeapFrog Didj
  • NC600
• Samsung Exynos3
  • FriendlyARM mini210s

Clone the devtool repository:

git clone git://github.com/jkent/devtool.git

Put devtool's bin directory in your path:

export PATH=/path/to/devtool/bin:$PATH

Create a new device profile (substitue profilename for whatever you wish):

dt profile new profilename

Set the options however you like, exit, and save. Now enter a shell for your profile:

dt shell profilename

You should end up with a prompt that looks somewhat like this:

hostname@user:~ [dt:profilename]$

Alright, so now that you have devtool setup, lets go ahead and use it with a project. Lets say you just cloned the hypothetical 'wirligig' project. Change directory into it:

cd whirligig

You should be in your devtool shell still. Go ahead and configure the whirligig project:

dt config

And once again, set the options how you wish. Now that you configured the project, the only thing left to do is to build it. You have two options here; you can either build the project using make directly, or using dt build. If you have not used the toolchain you selected for your device profile before, devtool will automatically download and extract it inside the devtools/build-tools directory. Simple!

Devtool has a help system; dt help will show you a list of commands you can use and dt help command will show you usage information and details on that particular command. Don't be afraid to use it!

Devtool is also designed to be friendly for development. Check out developer.md
