I tried using the image at https://ftp.freedombox.org/pub/freedombox/hardware/pioneer/stable/freedombox-stable_pioneer_a20-olinuxino-lime2-armhf.img.xz
I see on my routeur that something called freedombox has an IP address, it responds to ping but http://that_ip_address does not respond and nmap does not detect anything on port 80.
Am I doing something wrong? I tried with two Pioneer boxes, same outcome.
EDIT: I left it 1h and now it works. Not sure why it took so long.
