Webench/MSP-EXP432P401R: MSP432 Launchpad wont download via TI XDS

Brett O'Connor1

Part Number: MSP-EXP432P401R

Tool/software: Webench

I have just started working with the MSP432 Launchpad. I was able to compile and download the "Out of Box" example. I have started writing my own code starting with the UART so I can output debug message. I got the UART working and then I start playing with the main clock. I changed it to 48MHz and now I cannot download anything. I tried changing it back to 3MHz and I tried downloading the "Out of Box" again.

I am using IAR Workbench 7 Kickstart. I don't have any compile errors, it starts the debug/download then I get the foloowing in my debug log:

    Ok, SO I have tried using another computer. I now get an error message:

    "Tue Dec 27, 2016 09:39:15: Fatal error: Failed to connect to the XDS emulator (connect ICEPick)... (Error -122 @ 0x0) A bad parameter value was detected within a function. It is likely a problem with `SC_ARGS' in SMG_call(). (Emulation package 6.0.407.6) Session aborted! "

    I have also tried updating the firmware on the XDS1100 emulator. I was able to update/rollback to variouse firmware versions, but I still recieved the same error message when I try downloading to the MSP432 device.

    BTW, Thank you Britt for moving the thread.

    BUMP

    I have since tried programming with a Blackhawk USB100v2-ARM JTAG Emulator and I still get the same error message.

    Any help/suggestions would be great!

    Thank you,
    Brett

    Brett,
    When you changed the frequency to 48Mhz did you make any additional changes to support 48Mhz operation (Vcore=1, Flash wait state = 1 or 2 if you are using the revision B silicon - black launchpad)? You may need to perform a factory reset to get the device back into a working condition.

    The error message states that you have a piece of silicon that is no longer supported. You may want to look into getting a new launch-pad with the latest material.

    Hi Chris,

    I am using a Rev 2 Launchpad (red solder mask), and I did not make any additional changes to support 48MHz. I started with the sample code from "430BOOST-SENSE1_CapTouch_MSP432P401R" which has the frequency set to 3MHz. When I got my UART working I started playing around and turn the frequency up. My initHardware() routine is the following:

    void initHardware(void){
  //Set P1.0 to output direction
  GPIO_setAsOutputPin(
                      GPIO_PORT_P1,
                      GPIO_PIN0
                        );
  GPIO_setOutputHighOnPin(GPIO_PORT_P1,GPIO_PIN0);
  
  /* Initialize main clock to 3MHz */
  MAP_CS_setDCOCenteredFrequency(CS_DCO_FREQUENCY_3);
  MAP_CS_initClockSignal(CS_MCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_1 );
  MAP_CS_initClockSignal(CS_HSMCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_1 );
  MAP_CS_initClockSignal(CS_SMCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_1 );
  
  
  /* Selecting P1.2 and P1.3 in UART mode */
  MAP_GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P1,
                                                 GPIO_PIN2 | GPIO_PIN3, GPIO_PRIMARY_MODULE_FUNCTION);
  
  
  /* Configuring UART Module */
  MAP_UART_initModule(EUSCI_A0_BASE, &uartConfig);
  /* Enable UART module */
  MAP_UART_enableModule(EUSCI_A0_BASE);
  
}

    I will try a factory reset . I found this page explaining the process with CCS 

    http://www.davitrenou.com/en/launchpad-msp-exp432p401r-demarrage/

    Is it possible to do this in IAR Workbench?

    Thank you!

    Ok I performed a factory reset using CCS7. I am still not able to program the device with IAR though. I have not used CCS very much but I was able to import an example project (Blink LED) and program the device with CCS7.

    Seems link I don't have the target configured correctly in IAR or something. I am not able to program the device in IAR using known good projects.

    Hey Brett,

    Couple of things:
    Factory reset (CCS) : e2e.ti.com/.../1854733

    Setting Vcore and flash wait states for > 24Mhz operation:
    e2e.ti.com/.../2071064

    I am not aware of an IAR method of factory reset, so using CCS is appropriate (e2e.ti.com/.../493777 ).

    I will see if I can recreate on my side.

    Thank you Chris! I was able to do a factory reset and I have been able to program with CCS. IAR still gives me the same error though.

    Brett,
    After the factory reset, IAR still gives an error? Or does it still have an error with the change to 48Mhz that you described earlier?

    Thanks,
    Chris

    Hi Chris,

    I am not sure what the problem was, but it seemed to boil down to user error. I continued to get the same error with IAR, so I started using CCS. I ordered another dev kit from Digikey, but they were backordered. Three weeks later it came in and I was not able to flash the second dev kit with IAR. 

    I worked from home a few days last week and I was able to flash both kits with IAR on my home computer. My home computer is where all the problems started (changing the clock without changing the core voltage). Monday I reinstalled IAR on my work computer and now IAR is running smoothly. 

    Thank you very much for your help. The factory reset did the trick. Still not sure what I did to IAR.

    ~Brett
