What are some of the common hardware and software errors or issues you run into when developing firmware?

"While there are a wide variety of issues I encounter in my work as a firmware engineer, some of the more common ones include damage to the system from static discharge or power surges and short circuits which impact the function of the software, firmware, or operating system. There are also common issues with component malfunctions, errors caused by users, and missing information due to memory address malfunctions. It is difficult to prevent some of these, but recognizing the cause of the errors enables me to quickly address and resolve them."
