Error when using MSP430 driver library: "Only large data model supported for this ROM."

I'm relatively new to MSP430-programming and want to use the driver lib (https://www.ti.com/tool/MSPDRIVERLIB) for the MSP430FR2355. I included the library "driverlib.h" in an new empty project with the following code:

#include <msp430.h>
#include "driverlib.h"


/**
 * main.c
 */
int main(void)
{
    WDTCTL = WDTPW | WDTHOLD;   // stop watchdog timer
    
    return 0;
}

Unfortunately when compiling I get the following error message:

"{path}\TestLaunchPad\driverlib\MSP430FR2xx_4xx\rom_headers/rom_driverlib_fr235x.h", line 39: fatal error #35: #error directive: "Only large data model supported for this ROM.", where {path} is the location of the project on my computer.

The affected part in the file rom_driverlib_fr235x.h of the library is the following:

#if (defined(__TI_COMPILER_VERSION__) && !defined(__LARGE_DATA_MODEL__)) || \
(defined(__IAR_SYSTEMS_ICC__) && (__DATA_MODEL__!=__DATA_MODEL_LARGE__))
#error "Only large data model supported for this ROM."
#endif

I don't understand, what I am doing wrong or how I could specify the large data model, respectively.

Does anyone know how to solve this problem?

Thanks for your support.

Solution

  • I got an answer on another forum. Maybe someone else faces the same problem, so I'll post the solution here:

    In Code Composer Studio go to Properties -> Processor Options and try the settings as shown in this screenshot.
