Hi,
I purchased new launchpads of F280025C and tried to debug the control suite HRPWM example on launchpad. I am facing below error:
IcePick_C_0: Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register. 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 9.2.0.00002).
I verified the JTAG connection of launchpad and attached the report of it. Kindly go through the JTAG test connection report and suggest me a solution to fix this problem. Thanks in advance.

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioxds110.dll'.
The library build date was 'May 7 2020'.
The library build time was '21:10:18'.
The library package version is '9.2.0.00002'.
The library component version is '35.35.0.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '5' (0x00000005).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.
-----[Print the reset-command hardware log-file]-----------------------------
The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the XDS110 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for XDS110 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.
The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

Prasad,
First of all, controlSUITE is not maintained any more. Please download latest C2000Ware SDK. It can be downloaded from:
https://www.ti.com/tool/C2000WARE
Then, try example from SDK.
/Users/a0132919/ti/c2000/C2000Ware_4_02_00_00/driverlib/f28002x/examples/hrpwm
When imported the project, make sure you switch to CPU1_LAUNCHXL_RAM build configuration.
and TMS320F280025C_LaunchPad.ccxml is active.
Regards, Santosh
Thanks for the response. I picked an example from C2000ware and tested it by changing target configuration file, It was working.
