Great! I suppose this is the device that Alex mentioned.
The GitHub repo modified last time in 2022... no TCP stack, just UDP.

I just googled it. Here's getting started, I think I followed this
one when played with it, some time ago.
Also, there was examples of so-called standalone apps which you
can just upload to your dev, without updating u-boot itself.
And I vaguely remember that it could generate u-boot.elf for host
machine and run it in userspace for testing purposes. But right
now I can't google anything useful about it. So qemu is the best
option to start, indeed.

Nope. I’ve searched the web for the Nexus series tablets and

FreeBSD forum.
