CC2650STK: The board does not work after reconnecting the power

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2640

Dear TI experts,

I'm debugging a cc2650stk with CCS11. The code is based on sensortag's example projects (sensortag_cc2650stk_app and sensortag_cc2650stk_stack). I only modified the code in the app part.
The problem I'm currently having is that the app only works when I flash the program to the board or debug using CCS. Once I disconnect power (cc devpack debug board) and then reconnect power or insert a CR2032 battery, the board doesn't work at all until I flash it again or download the app to the board using debug.
May I ask why this happens and how to solve it?
Compiling and downloading the program is carried out according to the figure below.

Best regards,

Will

    Hi Will,

    The SensorTag project relies on the BIM application to be loaded alongside the main application so that it can perform OAD operations.  The line immediately below your screenshot mentions "Sample applications that implement the Over the Air Download (OAD) firmware update capability require the Boot Image Manager (BIM) project to be built. Refer to the CC2640 BLE OAD User's Guide for more details."  Thus you can read docs\CC2640 BLE OAD User's Guide.pdf for more information.  This will allow the BIM application to perform any critical activity before entering the main application after each device reset.

    Regards,
    Ryan
