Bare Metal programming A13

Programming with no OS, development tools and poor documentation isn't easy therefore this page is currently a work in progress. It will be updated as the author works out more about the process

Stand alone program running with uboot

The linux operating systems shown in the wiki runs on an SD card however it is booted using u-boot. U-boot sets up the CPU, memory and a few other things then starts Linux executing.
The following method outlines how to create a program that replaces linux but still relies on u-boot for setup.

Tools

- Computer for cross compiling the program and uboot, such as a linux computer
- SD card and SD card reader / writer
- A13 olinuxino board
- Serial adapter for the A13 olinuxino board (Only way to work with uboot as no screen is configured in uboot)
