This is my 3rd Buildroot howto, please read the previous ones in order to get started!
This howto was made using a Debian Squeeze 6.0 build host, with Buildroot 2011.02 (latest snapshot from the git repository)
Download and configure Buildroot :
Get the latest Buildroot and start configuring it (as a regular user)
$ git clone git://git.buildroot.net/buildroot
$ cd buildroot && make menuconfig
How to build a tiny Linux MP3 Player System using Buildroot
Do you have an old spare computer that is rotting somewhere in your attic/cellar? Why not recycle it into a MP3 jukebox! 🙂
An old rig (Pentium 1/2/3-class) with 64Megs of RAM and USB connector will do!
No Harddisk required, a CDROM drive is optional in case that booting from USB doesn’t work.
We will design our (minimalistic but fully automated) Linux system so that a screen and a network interface aren’t even required.
Have you ever tried to install a modern Linux distro onto a small capacity (usually 32 megs or even less) usb drive or compact flash card?
Even with a minimal install, such a distribution will not fit! Major Linux distros like Debian/Slackware/Arch/etc need a bare minimum of 300-400 megs of disk space.
The only minimal system I have been able to install so far on a 128Meg disk is NetBSD ( http://www.netbsd.org ).
But there is a way to achieve such a thing : we will be using Buildroot in order to generate a very small (embedded) Linux system (targeted at a standard intel x86 computer)
