　　Is it really worth paying for professional ARM? Cortex?-M development tools when there are so many free-of-charge alternatives available？ What can these tools offer to make them worth thousands of dollars per developer？ The answer depends on how much an undetected bug could end up costing you.

　　If you develop embedded software for a living， you are no doubt familiar with that uncomfortable feeling of knowing that your code contains a few hidden bugs. Even the most professionally designed product， subject to thousands of hours of rigorous testing， can end up on the market with bugs undetected. Customers have mostly learned to accept this， possibly because the vast majority of embedded system failures are merely annoying. The user experiences a hiccup， tries again， shrugs， and carries on. A little data got lost， and nobody got hurt.
