An understanable sentement, but its not just about me (though I actually own two
of the same dvr's). There is a large number, if reports are to be believed, of
more or less identical dvr systems with the same security holes and hard-coded
credentials, with no vendor firmware updates. In addition, I am also in possesion
of the chip vendor sdk with full source code for the kernel and modules and a
host of pertenant datasheets. My end goal is something along the line of openwrt
or lede for these systems in the interest of the community at large.

I'm not averse to the concept of hard work, and while I'm very experienced when
it comes to kernel hacking I think I can manage well enough with relevant source
and examples, of which there is a large amount.

One concern I have is dealing with devicetree, but I think I can manage.

That's intriguing. I'm interested to know what this model is and where
it can be bought, and also to see all the sdk. BTW have you got sdk from
manufacturer after asking for it, or otherwise? Are manufacturers keen
to answer technical questions?
