... which shouldn't surprise you.

What I meant was that the most common things the FAE hears in this regard is that the device is misbehaving in some way, and, most often, it's not the device at all, but some other part of the development effort that wasn't properly implemented or even thoroughly investigated.

When I send in ASM source code and binaries, along with "pictures" from the logic analyzer and/or oscilloscope, in parallel with a trace of the instructions executed in the "suspect" sequence, I normally am not met with skepticism. When one has "pictures" indicating that the timing is at odds with what the datasheet says, or that the execution otherwise is at variance with the datasheet, one is normally taken seriously. The evidence has to be persuasive, though.

You're quite right in that there's no reason to send 'em HLL source and claim it won't work. They'll just toss it in the rubbish.
