4.2.2 ZC Node

Open the workspace file zc_light_sink_CC26X2R1_LAUNCHXL_tirtos_ccs.projectspec with the correct version of CCS. The project file is found in the following folder after installing the SimpleLink CC13X2/CC26X2 SDK ^[5]:

C:\ti\simplelink_cc13x2_26x2_sdk_<version>\examples\rtos\<LaunchPad>\zstack\zc_light_sink\tirtos\ccs

With Zigbee 3.0, Base Device Behavior was introduced to allow for common network commissioning, such as automatic Finding & Binding mode, for a simplified commissioning process in Zigbee devices. In Section 4.2.5, it is explained how to start commissioning devices into a Zigbee network. To enable convenient features, such as storing storing and restoring the binding information after a device reset, ensure that the NV_RESTORE predefine symbol is defined in the project, which is defined by default in the projectspec. For more information about the NV_RESTORE compile option, see the Z-Stack Overview in the Z-Stack User's Guide^[6].

When programming a board with NV_RESTORE option defined for the first time with a new application, it is important to always erase the flash to ensure that all old data is erased to avoid a freshly programmed device behave strangely based on old stored NV data.

To erase the flash, first start a Debug Session on the device by right clicking on the project in Project Explorer → Debug As → Code Composer Debug Session. This will recompile the project if any changes were done. Once the Debug Session is started, click Tools → On-Chip Flash. Ensure 'Necessary Sectors Only (Retain untouched content within sector)' is selected, and click 'Erase Entire Flash' button, shown in Figure 4.
