      Getting Started


      If you are unfamiliar with the WICED SDK, please refer to the

      WICED Quickstart Guide located here: <WICED-SDK>/doc/WICED-QSG2xx-R.pdf

      The WICED Quickstart Guide documents the process to setup a computer for

      use with the WICED SDK, IDE and WICED Evaluation Board.


      The WICED SDK includes lots of sample applications in the <WICED-SDK>/Apps directory.

      Applications included with the SDK are outlined below.



      apps/demo : Demonstration Applications

         - Applications demonstrating how to integrate various WICED API features


      apps/snip : Application Snippets

         - Various applications to demonstrate usage of individual WICED APIs    



      apps/test : Test & Utility Applications

         - console      : Provides various test features including Iperf for throughput testing

         - mfg_test     : Manufacturing Test application to enable radio performance and certification testing


      apps/waf  : WICED Application Framework

         - bootloader   : Bootloader application used in conjunction with the WICED Application Framework

         - sflash_write : Serial flash application used to write data into external serial flash


      apps/wwd : Wiced Wi-Fi Driver Applications to demonstrate advanced usage of the low layer Wi-Fi driver


      To obtain a complete list of build commands and options, enter the following text in the

      base WICED SDK directory on a command line:

      $> make


      To compile, download and run the Wi-Fi scan application on the Broadcom BCM943362WCD4 evaluation platform,

      enter the following text on a command line (a period character is used to reference applications

      in sub-directories) :

      $> make snip.scan-BCM943362WCD4 download run


      The default RTOS and Network Stack components are defined in the WICED configuration makefile

      at <WICED-SDK>/tools/makefiles/wiced_config.mk. The default I/O bus component is defined in the platform

      makefile at <WICED-SDK>/platforms/<Platform>/<Platform>.mk. Defaults may be bypassed by specifying the

      component as part of the build string if desired as shown in the following example.

      $> make snip.scan-BCM943362WCD4-FreeRTOS-LwIP-SDIO download run


      Source code, headers and reference information for supported platforms are available

      in the <WICED-SDK>/platforms directory. Source code, headers, linker scripts etc that

      are common to all platforms are available in the <WICED-SDK>/WICED/platform directory.

      Known Limitations & Notes




      * Description - WICED_Audio: DUT resets if incoming call received/outgoing call initiated during Airplay streaming.

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - WICED_Audio: Play/Pause/FWD/BCKWD does not work with Mac Book Air and BTW.

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - snip.email: Email is not being send shows error

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - snip.https_server: Showing error in console while opening the webpage

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - snip.ping_webserver" is not working properly in debug mode, giving exceptional error also for snip.https client and demo.appliance apps

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - demo.temp_control: App stuck at the initial phase of booting up

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - snip.thread_monitor not working properly in both release mode and debug mode

         Workaround  - No work around

         Resolution  - Targeting to be fixed in the next SDK release



      * Description - Switching from Airplay to Bluetooth may result in silence if Bluetooth connection is established after the Airplay streaming has commenced.

         Workaround  - Switching back a second time should resolve the issue.

         Resolution  - Targeting to be fixed in the next SDK release


      * Description - Switching between Bluetooth music and Handsfree voice may fail after a few iterations

         Workaround  - None

         Resolution  - Targeting to be fixed in the next SDK release



      * Features not yet supported in WICED-SDK-3.5.2

         - IAR Embedded Workspace native support



         - WAC procedure is not supported for AP mode with WEP security



         * Platform Restrictions:


               - Wi-Fi Direct not support

               - SPI bus not supported


               - Wi-Fi Direct not supported

               - WPS may timeout with some access points


         * Wi-Fi Powersave (1)

             The WLAN chip requires an external 32kHz sleep clock input during powersave.

             Platforms that do not support Wi-Fi powersave (per the table above) are

             not capable of driving the WLAN sleep clock. An external 32kHz clock is

             required for these platforms.




      * libc does not include support for printing uint64_t (long long)


      * RTOS detection may cause OpenOCD to crash in the following situation:

           GDB has an elf containing a known RTOS loaded, and your app is using the

           RTOS memory for other purposes. This situation may occur while debugging

           the bootloader

           SOLUTION : Remove " -rtos auto " from the <WICED-SDK>/Tools/OpenCD/OpenOCD

                      .cfg file that matches your hardware debugger

                      (ie. BCM9WCD1EVAL1.cfg for WICED Evaluation Boards)



      * For the 43362, AP mode when running with Wi-Fi Direct is limited to 2 STA clients



      * P2P feature

           If the board's MAC address is locally administered then it needs to be modified

           to become a global address or P2P will not initialize.

           First build the application using the SDK, then find the

           generated_mac_address.txt file and modify the MAC address.

           Ex: Change text "macaddr=02:0A:F7:9c:76:f2" to "macaddr=00:0A:F7:9c:76:f2"




      The GNU ARM toolchain is from Yagarto, http://yagarto.de



      Programming and debugging is enabled by OpenOCD, http://openocd.berlios.de



      The standard WICED Evaluation board (BCM9WCD1EVAL1) provides two physical

      programming/debug interfaces for the STM32 host microprocessor: USB-JTAG and direct

      JTAG. The WICED Evaluation board driver additionally provides a single USB-serial

      port for debug printing or UART console purposes.



      The USB-JTAG interface is enabled by the libftdi/libusb open source driver,


      The direct JTAG interface works with third party JTAG programmers including

      Segger, IAR J-Link and Olimex ARM-USB-TINY series. OpenOCD works with the libftdi/libusb

      USB-JTAG driver shipped with the WICED SDK and commercially available JTAG drivers

      available from third party vendors.



      Building, programming and debugging of applications is achieved using either a

      command line interface or the WICED IDE as described in the Quickstart Guide.



      Instructions to use the IAR toolchain are provided in a README located in the

      following directory: <WICED-SDK>/Tools/IAR
