define USAGE_TEXT
Aborting due to invalid targets

Usage: make <target> [download] [run | debug] [JTAG=xxx] [no_dct]
       make run

  <target>
    One each of the following mandatory [and optional] components separated by '-'
      * Application (apps in sub-directories are referenced by subdir.appname)
      * Hardware Platform ($(filter-out common  include README.txt,$(notdir $(wildcard WICED/platforms/*))))
      * [RTOS] ($(notdir $(wildcard WICED/RTOS/*)))
      * [Network Stack] ($(notdir $(wildcard WICED/network/*)))
      * [MCU-WLAN Interface Bus] (SDIO SPI)

  [download]
    Download firmware image to target platform

  [run]
    Reset and run an application on the target hardware (no download)

  [debug]
    Connect to the target platform and run the debugger

  [JTAG=xxx]
    JTAG interface configuration file from the tools/OpenOCD dirctory
    Default option is BCM9WCD1EVAL1, direct JTAG option is jlink

  [no_dct]
    DCT downloading is disabled and the DCT remains unmodified.
    Only valid when the 'download' option is present

  [factory_reset_dct]
    Generates a factory reset DCT

  [VERBOSE=1]
    Shows the commands as they are being executed

  [JOBS=x]
    Sets the maximum number of parallel build threads (default=4)

  Notes
    * Component names are case sensitive
    * 'WICED', 'SDIO', 'SPI' and 'debug' are reserved component names
    * Component names MUST NOT include space or '-' characters
    * Building for release is assumed unless '-debug' is appended to the target
    * Some platforms may only support a single interface bus option

  Example Usage
    Build for Release
      $> make snip.scan-BCM943362WCD4
      $> make snip.scan-BCM943362WCD4-ThreadX-NetX_Duo-SDIO

    Build, Download and Run using the default USB-JTAG programming interface
      $> make snip.scan-BCM943362WCD4 download run

    Build for Debug
      $> make snip.scan-BCM943362WCD4-debug

    Build, Download and Debug using command line GDB
      $> make snip.scan-BCM943362WCD4-debug download debug

    Reset and run an application on the target hardware
      $> make run

    Clean output directory
      $> make clean

    Build a Factory Reset image for the SPI serial flash
      $> make snip.ping-BCM943362WCD4  OTA=waf.ota_upgrade  SFLASH=app-dct-ota-download

         where: [OTA]=<OTA application build string>
                         Build string options are App name, RTOS and TCP stack ONLY
                <SFLASH>=<app>-[dct]-[ota]-[download]
                         where:
                            app      : Add the application to the image
                            dct      : Add the DCT to the image
                            ota      : Add the OTA application to the image
                            download : Download the image after creation
