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.
This howto will show us how to manually create a bootable USB (flash) drive using the EXTLINUX bootloader.
Unlike SYSLINUX who installs on FAT formatted drives, EXTLINUX can be used for EXT2/3/4 and even btrfs formatted drives.
EXTLINUX is easier to use than GRUB.
Why use the EXT2 filesystem? It is recommended for flash drives as it is a non-journaled filesystem so the write operations are reduced compared to other journaled filesystems.
See http://en.wikipedia.org/wiki/Ext2 for more info.
