IAR error when using MSPware for Watchdog

Other Parts Discussed in Thread: MSPWARE, MSP432P401R
FYI...I do not see the WDT_A_CTL_SSEL_4 defined anywhere.  I get errors when compiling using IAR Embedded Workbench.

//***************************************************************************** // // The following are values that can be passed to the clockSelect parameter for // functions: WDT_A_watchdogTimerInit(), and WDT_A_intervalTimerInit(). // //***************************************************************************** #define WDT_A_CLOCKSOURCE_SMCLK (WDT_A_CTL_SSEL_0) #define WDT_A_CLOCKSOURCE_ACLK (WDT_A_CTL_SSEL_1) #define WDT_A_CLOCKSOURCE_VLOCLK (WDT_A_CTL_SSEL_2) #define WDT_A_CLOCKSOURCE_XCLK (WDT_A_CTL_SSEL_3) #define WDT_A_CLOCKSOURCE_BCLK (WDT_A_CTL_SSEL_4)
  • Hi Jim,

    I'm assuming you're using the MSP432 here. What version of IAR and MSPWare are you using? If you're using a LaunchPad, is it Rev1.0 or Rev2.0? Could you please post an image of the errors? Which code example are you using?

    This should help us narrow down your issue.

  • Hi James,

    Yes, I'm using MSP432 with

    IAR Embedded Workbench for ARM: 7.70.1.11486

    IAR Embedded Workbench shared components: 7.5.1.4405

    MSPware: v3_10_00_09

    Here is a copy of the Error.  I believe there is no XCLK for the WDTSSEL watchdog clock source as #defined in the wdt_a.h in the current library.  Also, these #defines are duplicated in the msp432p401r.h header.

  • Hi Jim,

    Thanks for providing details about your work space.

    Like you pointed out and according to Table 15-1 in the Technical Reference Manual, the proper clock sources are SMCLK, ACLK, VLOCLK, and BCLK. I'm using MSPWare v3_30_00_18, and I don't see "WDT_A_CTL_SSEL_4" as a #define in 'msp432p401r.h' (found at C:\ti\msp\MSPWare_3_30_00_18\driverlib\inc for me).

    From your version to my version on MSPWare, this must have been fixed. However, in 'wdt_a.h' (found at C:\ti\msp\MSPWare_3_30_00_18\driverlib\driverlib\MSP432P4xx for me), I do see "XCLK" and "WDT_A_CTL_SSEL_4".

    I'll submit a bug to fix this. Thanks for bringing it to our attention! In the meantime, which file is shown in your screenshot above? It looks like a code example, and I see it's using "WDT_A_CTL_SSEL_4", which we should fix too.
