Intel Edison Gateway Setup from Scratch

  1. Get the jubilinux edison-linux-helper:

     git clone https://github.com/jubilinux/edison-linux-helper.git

  2. Get jubilinux image inside of the repo:

     cd edison-linux-helper
 wget http://www.jubilinux.org/dist/jubilinux-v0.1.1.zip
 unzip jubilinux-v0.1.1.zip

  3. Add a patch to the patches folder so that it gets applied.

     cd patches
 wget https://raw.githubusercontent.com/lab11/gateway/c38d090fb699b01a4f2bba36a60741714db95442/buildroot/external/board/lab11/edison_v3-3.10.98/patches/linux/linux-0001-edison-spi-yesheng.patch
 cd ..

  4. Select the correct kernel modules

     make menuconfig
    • Enable Device Drivers/Network device support/USB Network Adapters/SMSC LAN95XX based USB 2.0 10/100 ethernet devices
    • Enable Device Drivers/Network device support/USB Network Adapters/QMI WWAN driver for Qualcomm MSM based 3G and LTE modems
    • Enable Device Drivers/USB support/USB Serial Converter support/USB driver for GSM and CDMA modems
    • Enable Device Drivers/USB support/USB Serial Converter support/USB FTDI Single Port Serial Driver
    • Make Device Drivers/GPIO Support/PCA953x, PCA955x, PCA957x, TCA64xx, and MAX7310 I/O ports "M" for module.
    • Disable Device Drivers/Sound card support

  5. Build the kernel:

     make

  6. Patch up jubilinux with the new kernel and modules:

     make collected
 sudo ./dfu-image-install.sh `pwd`/jubilinux

  7. Perform any device-specific configuration

    If there are any configuration files to load, if you'd like to assign a specific MAC address, or if you'd like to install any special software, it's much easier to do that now by mounting the image locally and making any changes before flashing.

    To make changes, mount the .home and .root files. Any home directory changes, such as updating repositories are done in the .home partition. Any configuration files are edited in the .root file.

    (n.b. https://github.com/alperakcan/fuse-ext2 worked well for mounting ext4 images on mac)

    When flashing a gateway, edit etc/network/interfaces to change the MAC address of the device. Example

     auto eth0
 iface eth0 inet dhcp
 	hwaddress ether c0:98:e5:c0:00:10

    If using sensu, its configuration file, etc/sensu/conf.d/client.json, must be edited with the proper client name and address.

  8. Flash jubilinux to the Edison.

    Before plugging in the gateway have a terminal window open and ready to connect (i.e. miniterm /dev/tty.u[] 115200, where [] is your cursor ready to hit tab). When the edison boots you have a short window to "Hit any key to stop autoboot".

    Plug the Gateway into your computer with the right micro USB connected (the one inbetween the two other USB headers on the board. Make sure the switch near the USB headers is flipped to the left.

    In your serial console, type run do_flash:

     Hit any key to stop autoboot:  0
 boot > run do_flash
 Saving Environment to MMC...
 Writing to MMC(0)... done
 GADGET DRIVER: usb_dnl_dfu

    Then, in another terminal:

     cd jubilinux
 sudo ./flashall.sh

    If you get errors, you may have to install drivers in windows

     [Intel Driver](https://software.intel.com/en-us/iot/hardware/edison/downloads)
 [D2XX Direct Driver](http://www.ftdichip.com/Drivers/D2XX.htm)

    Errors also occur if you have not run the script as root. You can run sudo dfu-util -l to check that the Edison DFU device has been found.

    This will take a while to run. It will flash several things, and then reboot the board

     $ ./flashall.sh
 Using U-Boot target: edison-defaultcdc

    Sometimes, the reboot will correctly allow flashall to keep going, sometimes the kernel will manage to boot again, in which case you'll have to manually reboot the Edison, catch it (any key) and run do_flash again. The flash script will automatically resume:

    (n.b. if you'd left this unattended, your terminal may be full of garbage b/c the Edison ups the baudrate of the serial link at some point during bootup. Everything is still fine, just reboot and it will reset to 115200.)

    This step will take a while. Be sure to look carefully at each flash step, as it will sometimes fail, but the flash script will print success anyway.

  9. Plug in a micro USB cable to the left micro USB port. Connect to the edison over UART with something like:

     miniterm.py /dev/ttyUSB0 115200

  10. Login with

     user: edison
 pass: edison

  11. Become root. Password is edison.

     su

  12. Connect to Wi-Fi or flip the switch and plug in ethernet.

     ifconfig wlan0 up
 iwconfig wlan0 essid "4908airwaves"
 dhclient wlan0

  13. Install sudo.

     apt install sudo

  14. Create "debian" user to match the BBB.

     adduser debian

  15. Allow debian to sudo and read log files:

     usermod -a -G sudo debian
 usermod -a -G adm debian

  16. Get rid of edison user.

     passwd -l edison
 sudo rm -rf /home/edison

  17. Install dependencies

     apt install vim bluetooth bluez libbluetooth-dev libudev-dev libavahi-compat-libdnssd-dev

Remaining Setup

See the shared instructions.

Copying image

Found some OK instructions here and here.

  1. Make sure there is an SD card in the gateway.

  2. Run the save edison script:

     /home/debian/gateway/edison/save_edison_image.sh <version> <flags>

    For example:

     /home/debian/gateway/edison/save_edison_image.sh 1.88.0 edison_v3-umich

3 . To flash, use this: https://github.com/lab11/gateway/tree/master/edison/v3
