What are common challenges faced when developing bare metal embedded software?

Bare metal embedded software engineers often encounter challenges such as limited memory and processing resources, real-time timing constraints, and troubleshooting hardware-software interactions without the safety net of an operating system. Debugging can be particularly complex, as it often relies on low-level tools and a deep understanding of both the code and the hardware. Close collaboration with hardware engineers is usually required to diagnose and resolve issues. Developing for a bare metal environment demands careful planning, proactive testing, and a precise approach to resource management to ensure stability and reliability of the final product.
