Tutorial: Using GNU profiling (gprof) with ARM Cortex-M

Erich Styger of MCUonEclipse writes, “I have published a Sneak Preview how GNU gprof profiling looks for an embedded target ARM Cortex-M in an earlier post.
This tutorial explains how to profile an embedded application (no RTOS needed) on ARM Cortex-M devices with GNU gprof. Additionally I explain the inner workings to generate the data necessary for gprof.”
