MSPM0C1104: SWD debug/program error

Part Number: MSPM0C1104

Tool/software:

Hello,

In a custom board of MSPM0C1104, the SWDIO, SWDCLK, UART TX and GND are connected from a LP-MSPM0C1104 to a target MCU. This board was being able to be debugged with the XDS110 of the dev kit. A depopulated solder bridge connecting a GPIO with NRST I shorted in the board to enable wakeup on button press. And then the board stopped working. The error message shown is below. This persists even after removing NRST connection to the GPIO.

Error connecting to the target: (Error -614 @ 0x0) The target indicates there is an error condition from a previous SWD  request. Clear the error the condition, and try the SWD request again. (Emulation package 20.0.0.3178)

Please help in in resolving this issue. Specifically

1. Where can I get more details of the Error -614?

2. Would it help if NRST of target MCU is connected to XDS110 of dev-kit?

Thanks, Prithvi
