RTOS/LAUNCHXL-CC2650: LAUNCHXL_CC2650 connection error after running empty project main()

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2640

Tool/software: TI-RTOS

I try to create a simple project just to validate the jtag connection and cc2640 on board is alive.

So, I went into CCS-V7 to create a empty project with HelloWorld.

When I performed the "Test Connection" first time, it was OK.

Until I "debug" this HelloWorld empty project, after the project was loaded.... then connection is dead.

When I tried to perform the "TestConnection", below is what I got.  Anyone has idea how I may bring the board back alive ??

(NOTE : the whole setup was OK which I went through the ProjectZero training)

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 '-230' (0xffffff1a).
The title is 'SC_ERR_PATH_MEASURE'.

The explanation is:
The measured lengths of the JTAG IR and DR scan-paths are invalid.
This indicates that an error exists in the link-delay or scan-path.

  • Hi,

    Was the project downloaded to the board before you performed the TestConnection the first time? And are you able to download a different project now if you try that?

  • 10 mins ago, the board is dead with CCS-V7 access. I tried ProjectZero that was working yesterday to perform "Test Connection" and it will failed.

    Just now, I use the FlashProgrammer2 to flash the release hex from TI-SDK, then everything back to normal.....

    So, the major issue I have : what has been missing from the "Create New CCS empty project" ??
    I have removed "--entry_point ResetISR" in order to build the project.
    What I am hoping for is, CCS should able to boot the mcu and reach the main()...
    The best is : if I can able to dis-assemble from bootup after mcu rest
