  • Hi,

      When does this happen? Is this the first time you use XDS110 on a new board? If not, have you had any program running on the MCU before the XDS110 connection issue occurred? In another word, have you had any prior success loading and debugging any program on your board? Do you remember what was the last program running on the board? The debug probe will normally fail to connect to a target if you have some program that puts the MCU in low power mode (e.g. hibernate or deepsleep) that does not have a means to wake up. During low power mode, the clock is shut down. Without a running clock, the debugger cannnot connect to the target. 

      Do you have another board to connect using XDS110. If you have another board and the connection is good then it means the XDS110 debug probe is in good condition. The problem is more board related. 

     If your board is a LaunchPad you can use the LM flash programmer to unlock the device. See section 5.3.1. If you have a custom board then you can use the below command dbgjtag.exe –f @xds110 –Y unlock,mode=tiva” to unlock the device. See section 5.3.2. in the below app note for details.

    You can also use the Test Connection to find out if the JTAG scan chain is proper.
