Building Super Small Linux Computers From Scratch

Conventional wisdom says small, powerful embedded Linux like the Raspberry Pi, Beaglebone, or the Intel Edison are inherently manufactured devices, and certainly not something the homebrew tinkerer can produce at home. [hak8or] is doing just that, producing not one, but two completely different tiny Linux computers at home.

The first is based on Atmel’s AT91SAM9N12 ARM processor, but the entire board is just about two inches square. On board is 64 MB of DDR2 DRAM, a USB host and OTG port, and not much else. Still, this chip runs a stripped down Linux off of a USB drive.

The second board is based on the Freescale i.MX233. This board is similar in size and capabilities, but it’s not exactly¬†working right now. There’s an issue with the DRAM timings and a capacitor underneath the SD card is a bit too tall.

The real value of [hak8or]’s project is the incredible amount of resources he’s put into his readme.mds for these repos. If you’ve ever wanted to build an embedded Linux device, here’s your one-stop shop for information on booting Linux on these chips.
