CCS/MSP430FR2110: TI MSP430 cannot connect to device (error: unknown device, and could not erase device memory)

Part Number: MSP430FR2110
Other Parts Discussed in Thread: MSP430FR2000, MSP-FLASHER, MSP-FET

Tool/software: Code Composer Studio

I am using: 

  • the MSP430FR2110
  • the MSP_FET Flash emulation tool 
  • Code composer 
  • Mac computer 

After running the code to put MSP430 to sleep, I cannot connect to the device anymore. The MSP_FET Flash shows the message "Error connecting to the target: unknown device". Then, I updated the debug configuration to erase the MSP430 before flashing. Now, MSP_FET Flash shows the message "Error connecting to the target: Could not erase device memory". Can someone help me to connect to the MSP430 via MSP_FET Flash emulation tool?

code to put MSP to sleep:

__bis_SR_register(LPM3_bits)

    I tried connecting to the device using MSP flasher. with the same error ''unknown device":

    Press any key to continue...

    The hardware connection is definitely good. And, MSP-FET flasher is functional as I am able to connect to another part MSP430FR2000 using the same tool. The output from MSP-FLASHER:

    Hi Darryl,

    Can you share the code that you download to your MSP430 to us?

    And another tool you can try is http://www.ti.com/tool/download/UNIFLASH
