CCS/CC3200-LAUNCHXL: CCS Cloud does not connect to target

Part Number: CC3200-LAUNCHXL
Other Parts Discussed in Thread: ENERGIA, , CC3200

Tool/software: Code Composer Studio

Hello, 

I am using CCS Cloud and trying to load a program on CC3200-LaunchXL, but it continuously gives an error report "Error connecting to the target". The behavior is strange as I can access the board from Energia installed on my machine (not TI cloud). I even can access MSP432P401R launchpad from CCS cloud, but CCS cloud does not connect to CC3200-LaunchXL.I tried different things to make it work. I removed TICloudAgentBridge extension from my Chorme browser and reinstalled again, but it did not help. I uninstalled and reinstalled TICloudAgent on my computer, but it did not help. I changed the COM port number, but it did not help. I ran Energia before running CCS Cloud to make sure it is accessible and then I ran CCS Cloud, but it did not help. I connected MSP432P401R launchpad and then CC3200-LaunchXL, but it did not help. I can't think of anything else why this is happening.

If it helps, the problem starts with executing boostxl_sensors_sensorgui_msp432p401r_MSP_EXP432P401R_nortos_ccs on MSP432P401R launchpad. The project successfully executed. But when I connected CC3200-LaunchXL to do another project, CCS could not detect CC3200-LaunchXL anymore. I could access CC3200-LaunchXL before working with boostxl_sensors_sensorgui_msp432p401r_MSP_EXP432P401R_nortos_ccs on MSP432P401R. Please note that at this stage still I can access both board through Energia instated on my machine. 

This becomes very confusing for me. Could you suggest a solution for this this? 

Thank you,

    Interesting. So ever since you used boostxl_sensors_sensorgui_msp432p401r_MSP_EXP432P401R_nortos_ccs, you have never been able to connect to the CC3200-LaunchXL anymore?

    Can you reproduce the issue with logging enabled?

    Then attach the log to this thread.

    Thanks

    Hassan,

    Did you change the jumpers on the CC3200 LaunchPad in order to program the serial flash via the Energia IDE?

    CC3200 is a bit different than most of our MCUs.  The flash memory here is not your usual on chip flash it is serial flash.  

    From within CCS Cloud if you try to create a new Energia Sketch and select the Blinky example under Basics what is the error message that you get when you launch your debug session?

    Here are what my jumpers look like.  Not that J8 is on (near the top of the picture) and none of the SOP jumpers (bottom of picture) are on.

    Regards,

    John

    Hello Ki, 

    I do not see an option here to attache log files, so I replied to the email.

    Good day John, 

    I didn't change jumper settings. The jumper setting for yours in the figure is the same as mine except for J8 that it is without jumper for the sake of programming (connecting J8 to J2). 

    I tried the Blinky example, the matter is that neither debug or run can proceed as connection to the target can't be made. Stellaris In-Circuit Debug Interface/Cortex_M4_0 reports "Error connecting to the target". 

    Thanks.

    Hassan,

    Please add the jumper to J8.

    If I remove J8 I get:

    Add the jumper back and you will be able to connect and program the device in CCS Cloud

    CCS is not able to program the serial flash on this device. That little trick of connecting J2 to J8 will not work.

    John

    John,

    You are correct. By replacing J8, it correctly works. 

    It should say it is yet confusing, as it was working before by connecting J8 and J2 as we see in online documents. 

    Many thanks for your help. :)
