Address Space overflow

There are always ways to alienating yourself. But being silent instead of bringing up potential issues just means they pay for a consultant that doesn't deliver the full knowledge/experience.

While it is obviously not a good idea to cut someone at the knees by asking who was the fool to select a specific processor, there are lots of ways to point out the potential problems with the selected route and wonder if alternative routes - such as using a (similarly priced) processor with a large linear address space - would be an option to speed up the total development times and cut problem complexity.

Many times, people just don't realize the implications of having a processor with 256kB of flash but an adressing scheme that requires only a small part of that flash to be visible at any one time. Datasheets for the processor (or application notes) will obviously not spend time describing the issues with the processor. At best, the application note will describe the availability of code banking - making it sound like a nice feature of the processor instead of a cludge to work around a huge design issue.

Certainly can't dispute that.

I've witnessed it from both sides; and admit to being really ticked off in one situation where the management recruited a "sharp-as-a-knife consultant" who caused a product to be redesigned very late in the day because what we'd done was "so Heath Robinson" and should be chucked out.

The expert consultant really didn't understand what we'd done and why. He had pre-conceived ideas from which he would not deviate and he would not listen to technical or cost arguments. But the management liked him because he was oh so decisive.

Long story short, the expert consultant failed in his task, he was kicked out, our work was resurrected and the project was successfully completed.
