It's very often difficult to determine if a problem is caused by hardware or software. I had a problem with an NXP processor that would crash whenever the I2C interface was turned on. It sounds like software, but when all other tasks were halted and only the I2C ran, everything was fine. OK, maybe I'm running out of execution time? No, no problem there either. NXP eventually sent out an errata that the Vdd bond wire in the chip had too large of a voltage drop and would crash when the processor was pulling a great deal of current.
Actually, I have seen this phenomenon in various other development situations, as well, except that you could replace "firmware team" and "hardware team" with "hardware module 1 team" and "hardware module 2 team". I think it's human nature (at least for the engineer/scientist humans) to make up your mind what the problem is, and then proceed as though your notion is the truth -- until proven otherwise. Which is exactly what the hardware engineers did in this case.
Jason, configuration control and documentation are critical to ensuring that a design is correct and can pass from prototype to production. When "patches" go undocumented, as you discovered with the evaluation board, then it becomes impossible to correctly configure the system. Software has dealt with this situation for some time. Frankly, I always thought hardware did as well. Just goes to show...
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
