ECE497 Project: Multiple Partitions via U-boot
Team members: Michael J. Yuhas, Jack Ma
Contents |
Executive Summary
The goal of this project is to give the U-boot boot-loader the ability to mount different partitions on start-up. This would allow the user to dual-boot the beagle board by controlling the boot sequence with a user button or RS-232 link.
Currently we have discovered how to create mmc-cards with multiple partitions, and discovered a way to mount the different partitions as root during start-up using built in U-boot commands. Currently we are developing a command to allow the user to select the partitions from which to boot.
Plans for the duration of the project includes finishing development of the multiboot command and modification of the boot script to allow partition selection using the user button. We also intend to research booting from USB devices, but this will only be explored if time permits.

Theory of Operation
The current plan of attack for our project is to write a script that will run automatically in U-boot, allowing the user to select between different partitions.
