Camera configuration

Getting the camera up and running requires some initial setup of bootloader environment.

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

Hardware Settings

• gpio_default - List of default GPIO states on boot. each position consists of the GPIO number followed by the desired state:
  • O - Output, High
  • o - Output, Low
  • i or I - Input
