Software Based Fault Injection Framework for Radiation Tolerant MSP430 CubeSat Subsystems

Abstract

This thesis presents a software fault injection framework developed for MSP430-basedCubeSat subsystems to evaluate dependability under radiation-induced fault conditions. We implemented a three phase fault injection approach utilizing the Code Composer Studio API and on-chip JTAG interfaces, the framework automates bit-level fault injection and data collection to assist developers in early stage software hardening. Experimental results demonstrate the feasibility of software-implemented fault injection for low-cost, radiationtolerant verification of CubeSat microcontrollers.
