    I suggest you to install CCS Desktop version and install latest CC2640R2F SDK to import ProjectZero to test it.

    Hi Chen

    The problem was resolved after using CCS Desktop version.

    But when I started PuTTy and pressed the reset button, an error occurred.

    The attached is the screenshot of the PuTTy and CCS.

    Would you help me to resolve this?

    Best Regards,

    Tom.Liu

    What is the baudrate you use on Putty? Is it 115200?

    Hi Chen,

    It was "9600". After changing to "115200", logs are now output to Putty each time the Reset button is pressed. However, when I pressed the device's Reset button, the phenomenon that an error was output to the CCS Console remained. I reset the device many times, but the situation is not improved.

    The error message is as follows.

    Cortex_M3_0: Error: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.1.0.00007)

    Cortex_M3_0: Unable to determine target status after 20 attempts

    Cortex_M3_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

    Best Regards,

    When you press reset button, it's normal to see JTAG disconnected.
