I used to document the creation of a baremetal OS on an ARM device which uses the S3C2440 chip here : http://thesoulofamachine.blogspot.in/ http://thesoulofamachine.blogspot.in/ You can find the partially developed but documented code here: https://github.com/mindentropy/s3c2440-mdk https://github.com/mindentropy/s3c2440-mdk The board I use is the mini2440 single board computer. You can bring up the same on a beagle bone with some minor modifications when you are dealing with the peripherals.
