kaOS operating system and loader
We have created a real-time, multithreaded, preemptive operating system called kaOS for the Atmel Mega32 microcontroller, which loads and executes programs from a Secure Digital or MMC card.
We wrote this OS and created the SD/MMC card reader as a final project for Cornell's ECE 476 class taught by Professor Bruce Land. Our reason for choosing this particular project is that we were unable to find any OS for the Mega32 that doesn't have to be statically compiled in with a user program. In contrast, kaOS waits for a card to be inserted and a reset button to be pressed, at which point a program is loaded from the card and executed. At any time, a new card with a new program can be inserted and run. Executing a new program doesn't require reprogramming the Atmel processor.
