Damn! I just remembered where I've stored an old "toy" from 2015 Chaos Communication Camp…
Too bad the wiki is down, apparently the firmware has been updated in 2022.
If anyone has a copy of docs/wiki, I'm interested. Especially (but not exclusively) firmware flashing/upgade instructions.
Currently flashed versionj of hackRF and HackRF old don't seem to work (stuck at loading). Only TESTAPP and Camp parts boot properly 😭
