| | | | | When writing a freestanding application, it's generally necessary for the firmware engineer to handle runtime initialization. Even when a library like newlib includes a rudimentary implementation of crt0.o, initialization is a very application-specific process owing to the need to initialize hardware, memory, and other loading tasks. In this essay, we examine the current and historical implementation of executable initialization, finishing with a minimal implementation usable with firmware applications. Note: Most firmware applications need to address the initialization of .data and .bss from nonvolatile memory. That is not addressed in this essay. | |
