I have some of those at work: they're test platforms for the audio ICs, for things like SoundWire interfaces.

Dedicated test gear is different echelon. We've got some crazy-expensive RF test gear where I work that cost us way more than my house. That's an awesome corner of the world, with a combination of robust-but-fickle at every corner.
The sales volume is low, and the development cost is expensive, so the cost to purchase is also expensive. It's an interesting thing to think about, market-wise.
SoundWire. That's an internal[ish], hard-clocked, multipoint, digital audio bus, yeah? I don't know much about it. Looks like it's mostly useful for OE car audio applications?

This box I have is just a finished, retail-product, general-purpose pro audio DSP with a good amount of practical analog and digital audio IO. There are many others like it in the marketplace that do very similar things, but this one has a CVE that I want to exploit for my own purposes. :)

I really hate being secretive. I strongly prefer to just chat about stuff here, or there, or anywhere.
But even though I'm just some dude in Ohio, my HN comments consistently show up near the top of Google search results when looking at specific topics that I've covered, sometimes just in-passing, so I'm inclined to keep the details to myself for now.
I mean: In the grand scheme of things I haven't even been posting regularly here for very long, but more than once already I've Googled a question and found a link to an answer in my own comment here.
That can be problematic.
This is a great forum for open discussion, and for releasing information, and it is absolutely the wrong forum for secret skunkworks.
If I had a spare box so I could afford to potentially fuck this one up forever, I'd get on with it already. And then, of course, I would publish the results.
I wish I could spill the beans already and maybe get some great help from someone here who does this stuff routinely, but that scares future-me. If the devices can be rooted, then I want them all to be rooted (if useful) -or- better-secured (if not useful).
That sounds fine, except I don't want them to become botnet members, either.
It's a dilemma. There's a lot of this shit out there in the world that doesn't get updated.
