Hi Dan,

I'd like to use it for doing real-time lo-latency audio. Basically the
same way I'm using my Raspberry Pi.

Ambivalent. It sure is faster than a Raspberry Pi but RK3066 based
devices have some drawbacks:
* No easy debugging access, I have yet to find the TXD pad on my RK3066.
* Fragmented development efforts. There are a gazillion git repositories
with all kinds of kernel sources, tools, etc.
* There are simply a lot of RK3066 based devices around and since
RockChip refuses to release their kernel source code people hacking on
the RK3066/RK3188 depend on third-party manufacturers that do understand
how GPL works and release parts of the code. Still there are things
missing, I'm now searching for a way to access the NAND from within
Linux but there is no source code anywhere for accessing the NAND on
RK3066 based devices. Yeah, there are pre-compiled kernel modules but
those don't work on my install.
* Closely related to the above bullet, yesterday I decided to flash the
kernel to the kernel partition only to realize later that now I can't
boot into anything else but Linux. And I can't flash anything either
because I can't boot in the bootloader. Apparently I can short two pads
and have the device boot into recovery but that won't help me either
because I've flashed the recovery partition with, you guessed it right,
a Linux kernel.
* JACK doesn't run on my device it with an external USB interface. It
starts and then the kernel crashes.

So I'm thinking about getting another TV stick but then a model that is
easier to debug and that has some more community support.

It should perform notably

It does but development effort is far from finished so it doesn't work
as good as my Raspberry Pi. Well, at least WiFi works so I can just
power it up and SSH into it.

Regards,

Jeremy
