3.5.2 Performing a "Build and Download" from WICED Studio

The programming process depends on the OpenOCD programming utility, bundled with the WICED SDK

from Cypress. During development, the programming process can be started directly from within WICED

Studio. This is done by double-clicking a make target with the "download" directive specified as part of

the build string. For more information about build strings within the WICED environment, refer to the

README.txt in the top level 43xxx_Wi-Fi folder of your WICED SDK installation.

For example, to build and download the snip.scan application to your Sterling-LWB STM Expansion

Board, do the following:

1.) Double-click the "clean" make target to clean any previously built target files

2.) create a make target with the following build string:

snip.scan-LSRSTERLING_00950-ThreadX-NetX-SDIO download download_apps run

3.) Double-click the make target created in step 2. The "Console" tab near the bottom of the WICED

Studio window will display the status of the build and download. Once the build is complete, the

output files will be located in the 43xxx_Wi-Fi/build folder.

4.) If the USB cable is attached to the PC and the JTAG driver is installed as described in 3.5.1,

WICED Studio will proceed with programming the STM32F411 MCU after the build.

5.) In this example the 'download_apps' command was specified. This instructs the IDE to also

download the WLAN firmware to the external SPI flash (once this is done for your board,

"download_apps" may be omitted if you are just updating the application and not the WLAN

firmware).

As stated in the previous section, if you have never programmed the external SPI flash with WLAN

firmware (this will be the case for brand new Sterling-LWB STM Expansion Boards), you must do so at

least once before attempting to build and run any applications on the STM32F411 that use the Sterling-

LWB module.

To include programming of the WLAN firmware to the SPI flash in your build and download process, add

"download_apps" after the "download" command in your build string. This will trigger additional steps

during the programming process to utilize the sflash_write application to write the WLAN firmware to

the external SPI flash.
