Camera configuration

Getting the camera up and running requires initial setup of the bootloader environment. Most camera firmware images already have environment settings in them, and you only need to provide your wireless network credentials to get the camera online. However, if you are building firmware for a new camera, or if you are using a module firmware, you will need to provide the unvironment file yourself.

Find your camera model in /environment/ directory, copy its configuration file and save it as uEnv.txt. Replace the wlanssid and wlanpass values with your wireless network credentials. Copy the file to an SD card, insert the card into your camera and reboot.

Bootloader environment explained
