The latest code in the github is just the code. How did you make the live image that gets flashed to the sd card?
Download the latest Pwnagotchi .img file.
pwnagotchi-raspbian-lite-v1.5.5.zip (version will change with future releases)
the website sugests you use the balenaEtcher program wich in my case still seems to give the best results. 8 GB or higher Micro SD or higher is required.
next step would be to create a
config.toml file and configure it to you liking and put is on the SD /boot
hope this helps.
