Thank you
@Aussie Susan and
@KlausST for your clear comments.

I have a custom-designed PCB and uses an STM32F767 microprocessor. For uploading the executable codes to the microprocessor, I use an ST-Link adapter. According to the IDE screenshot (attached), the codes are stored in the FLASH memory of the microprocessor; however, after power off and cycles, I couldn't use the board so I suspect that whether the executable codes were not properly stored or the stored data graph on the screenshot has standard parameters. I have lots of peripherals and Bluetooth control on the PCB so I don't know how the Nucleo board can be used.

Thank you for the clarification on the parameters! I have a custom user interface (Matlab GUI) to control the parameter values in the microprocessor via Bluetooth. I hit the 'Run' (Green play button on CubeIDE and selected 'Release' at the 'hammer' icon) button to upload the executable codes (attached is the report that I got from the 'console' at the cubeIDE). Then, I make a Bluetooth connection between the interface (PC) and Bluetooth on the PCB. After that I test it, then it works (transmits set values of the interface and received converted analog signals). Next, I disconnect the Bluetooth with a button on the interface. Then, I physically disconnect/remove the ST-Link adapter. Then, I make a Bluetooth connection between the interface (PC) and Bluetooth on the PCB. After that I test it, then it works. Last, I powered off and on the PCB. Then, I make a Bluetooth connection between the interface (PC) and Bluetooth on the PCB (without the ST link adapter). After that, I didn't observe transmission (checking with the oscilloscope whether any signals are generating) and receiving (on the interface screen). In addition, on the power supply screen, the initial current consumption was 90 mA, then it decreased gradually to 55 mA after power was off and on.
On the other hand, while the ST-Link adapter was connecting to the PCB debugger connector, the system worked after powered off and on. Thus, the system operation is depending on the ST link adapter connection.
