LP-MSPM0C1104: Cannot connect debugger after setting watchdog

Part Number: LP-MSPM0C1104

Hi please help,

I configured a watchdog of period 15.63ms and PDBGCTL.FREE set to 1.

Now I cannot reprogram/flash the chip.

I am using the debugger of the launchpad Rev E3.

The error is: "Error connecting to the target: (Error -2063 @ 0x0) Unable to reset device. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 12.6.0.00029)".

Thanks in advance.

Hi Ankit,

This is a strange one. I'll take a look to see what might be the issue.

One more thing I would like to add is that the board is entering and exiting STANDBY1 by a GPIO interrupt. I tried programing in RUN0 and STANDBY1 but same error in both power modes.

Dennis: Thanks for posting this; I was looking for it last night.

Stating the obvious: This seems like a rather hazardous combination of settings, since (I suppose) the MCU will be resetting (frequently) while the debugger is trying to do its thing. I suggest keeping FREE=0.
