Buried Treasure and Map Files

Available in 33 days, 2 hours and 14 minutes

Often overlooked, the map file can provide a wealth of information to the intrepid developer. Map files can help:

  • optimizing for RAM usage and/or code space
  • updating firmware (with or without a bootloader)
  • debugging difficult crash bugs
  • statistical profiling

With so much information, how can you use it? Where do you look? How do you turn the wall of text and numbers into a true map of the code?

Elecia will demonstrate how to use map files. She will focus on an ARM Cortex-M but it will be relevant to other processors.
