I can't program my LaunchPad MSP432; the IDE can't connect to target. What's wrong?

Other Parts Discussed in Thread: CC3100BOOST, MSP432WARE

I was able to debug and program the MSP432 LaunchPad before and everything worked fine.

After some updates, I wasn't able to do so again. When I ran the Test Connection, I got the

following message:

The JTAG DR Integrity scan-test has succeeded. [End: Texas Instruments XDS110 USB Debug Probe]

It seems to me that the XDS110 USB Debug Probe is working fine. But when I tried to debug the 

MSP-EXP432P401R Out Of Box Demo, I got the error message:

CORTEX_M4_0: Error connecting to the target: (Error -1063 @ 0x0) Device ID is not recognized or is not supported by driver. Confirm device and debug probe configuration is correct, or update device driver. (Emulation package 6.0.83.1)

My CCS is  Version: 6.1.1.201508201800.        Compiler Version: TI v5.2.6

How do I fix this problem?

Thanks,

Sam

    Hi JH,
    After I reset the Debug Probe to default factory settings, I was able to download and debug the board again. It seems working.
    But when I tried to work on the "CC3100BOOST_MQTT-TwitterLED_MSP432P401R" example, I ran into the same problem again. I repeated the resetting steps and it always gave me this error message:

    CORTEX_M4_0: GEL Output: Memory Map Initialization Complete
    CORTEX_M4_0: GEL Output: Halting Watchdog Timer
    CORTEX_M4_0: Flash Programmer: Erasing main memory
    CORTEX_M4_0: Flash Programmer: Writing 32752 bytes to flash memory 0x00000000
    CORTEX_M4_0: Flash Programmer: Writing 20088 bytes to flash memory 0x00007ff0
    CORTEX_M4_0: Failed CPU Reset: (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 6.0.83.1)

    What is the problem now?
    How can I get "CC3100BOOST_MQTT-TwitterLED_MSP432P401R" example working?

    Thanks,
    Sam

    Hi JH,

    I can't see the post: e2e.ti.com/.../467612. The web page says:
    Access Denied
    You do not have permission to view/download this item.

    My Launchpad board and the Debug Probe worked fine before.
    Why do I have so much problem with it now?

    Thanks,
    Sam

    Sam,

    Sorry about that. It seems that was the wrong link anyway. Basically, can you perform the factory reset steps in www.ti.com/.../slau575 (section 7)?

    I am unsure of the complete reason why this has to be done, but it seems there is a miscommunication between different settings for the emulator depending on the version of CCS you have and version projects were initially made under. I believe there was a change on where some settings where pulled from.

    Let me know if these steps do not solve your issue.

    Regards,
    JH

    Hi JH,
    For most other examples in MSP432Ware, it worked if I performed the factory reset steps in www.ti.com/.../slau575 (section 7). It seems to me that I have to repeat that process for every project I created now. But why do I have to do that now for each one of those projects? I had no problem with them before some recent updates.

    But performing the factory reset steps in www.ti.com/.../slau575 (section 7) still didn't fix the problem for project "CC3100BOOST_MQTT-TwitterLED_MSP432P401R". I still have problem loading the code into the chip.

    Any suggestions?

    Thanks,
    Sam

    Sam,

    In order to investigate this issue further, can you provide your project? If you are not comfortable posting it directly to the forum here, please send me a private message.

    Hi Sam,

     Please find attached a working "CC3100BOOST_MQTT-TwitterLED_MSP432P401R" project. Could you please try this project with HW and let us know if you encounter the same problem.

      Thanks,

    Hi Jace,

    Thanks for sending me the *_RGB.zip file. After performing the factory reset steps in www.ti.com/.../slau575 (section 7), I was able to load the code into the chip without problems. I am going to pair it up with CC3100BOOST board to test the application.

    It would be nice that I don't have to perform the factory reset steps in www.ti.com/.../slau575 (section 7) for every new project I create from now on. Is there a way to fix that?

    Thanks,
    Sam
