Abstract

Over-the-Air (OTA) firmware updates are a critical function of modern embedded systems, allowing devices to receive software updates after deployment. However, any issues during the OTA process can render a device unusable.

TI processor families, such as the AM62 and other Sitara™ processors, offer powerful multi-core architectures and rich peripheral interfaces, making them particularly designed for industrial and automotive applications requiring highly reliable OTA updates. These processors integrate an ARM® Cortex® R5/M4 core and A53/A72 cores, supporting various memory interfaces and boot options, providing the hardware foundation for robust OTA systems.

This application note describes how to use TI processors to design more robust and flexible OTA systems, avoiding common OTA failure scenarios.
