Ben's notes

Jubilinux = Debian Jessie for edison.

• Hardware guide - Intel® Edison Compute Module
• Hardware guide - Intel® Edison Breakout Board

• Connect both USB cables to the Edison.
• Open serial terminal:

  screen /dev/ttyUSB0 115200

• Install dfu-util:

  sudo dnf install dfu-util

• Download the latest jubilinux version and unpack the archive.

• Run the flashall.sh script.

  sudo ./flashall.sh

• Reconnect power (bottom cable on photo above).
• Monitor the installation (using serial console on another window), it involves three reboots, so don't pull the cords yet.

• Change edison and root passwords, default password is edison.
• Edit /etc/rc.local For example:

  ### uncomment to disable USB device mode and enable host mode for the OTG port
  rmmod g_multi || true

• Configure WPA_supplicant:

  # wpa_passphrase SSID      # add output to /etc/wpa_supplicant/wpa_supplicant.conf
  
  # vi /etc/network/interfaces
  auto wlan0
  iface wlan0 inet dhcp
      wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
  
  # ifup wlan0

• If WiFi lags, disabled powermanagement (for example in /etc/rc.local):

  iwconfig wlan0 power off

• Update:

  apt-get update
  apt-get upgrade

• Configure powerbutton handling. See: http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/plain/meta-intel-edison-bsp/recipes-support/pwr-button-handler/files/

  wget http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/plain/meta-intel-edison-bsp/recipes-support/pwr-button-handler/files/pwr-button-handler.c
