Minimal Ubuntu distro for my mobile robot (pandaboard)

I'm developing a mobile robot application and i'm using a high-level board (pandaboard es) which can run linux operating system and a low I/O board to manage the sensors.

These two boards share data over ethernet while the high-level board controls a motor driver by using the USB port.

At the moment, i've installed Ubuntu Maverick on the high-level board and it works great.

The problem is that i'd like to minimize all the operating system functions, to use just the command line (i do not need the X server) and to avoid not-necessary resources consumption.

What i need to do on the high-level board is just to run a C program which takes information from the ethernet, do some calculations and send data over the USB.

So, what i need is:

- use ethernet
- use boost library, multi threading, I/O operations
- read/write on serial port (USB) with termios library
- sometimes, use a remote connection in order to control the system from another pc

Furthermore, i need to let the C program start automatically when the operatin system is powered up.

It is possible to start the C program when the operating system is on?
I have to use a bash script to do this?

Is there any Ubuntu minimal distro which i can use for my purpose?

(This is the board i'm using: http://en.wikipedia.org/wiki/PandaBoard)

Look at Damn Small Linux or TinyLinux.  I don't know if there are ports to ARM.

Compile the kernel yourself to build your own dist! Or use TinyCore Linux.

Building a new distro is a bit of work.   Packages don't build without problem and resolving these issues can take time.  Finding a usable distro and configuring it would be a much easier path.  Ubuntu and other distros allow you to select which packages you want to install.

If you really want to build a distro, take a look at the Buildroot and Yocto projects.  These are designed to build kernel and root file systems for embedded Linux systems.

Thanks for all you suggestions.

At the end, pandaboard was not suitable for me application so i had to switch to another hardware type and I decided to use a minimal Ubuntu installation.
