Example "boot from flash" applications for 8OD.
The source code for 8OD's standard bootrom which is used for serial download, to and booting from SPI flash.
Contains an example of how to make an image which runs from EPROM instead of using the standard bootrom. RAM is still required to store the stack and data.
