PSoC 6 MCU

Hi,

I'm trying to understand how to determine the core that is currently being compiled while defining the proper macros for each core. I can see from the device header file with something like:

#if ((defined(__GNUC__)        && (__ARM_ARCH == 6) && (__ARM_ARCH_6M__ == 1)) || \

     (defined(__ICCARM__)      && (__CORE__ == __ARM6M__)) || \

     (defined(__ARMCC_VERSION) && (__TARGET_ARCH_THUMB == 3)) || \

     (defined(__ghs__)         && defined(__CORE_CORTEXM0PLUS__)))

to determine which core header file to include (e.g., core_cm0plus.h or core_cm4.h).

Since I'm using ARMCC, is there any way to understand how __TARGET_ARCH_THUMB is defined to know which core the PSoC Creator is currently compiling?

Thanks!

These pre-defined MACROs are declared by the ARM compiler.  Please refer following on-line document.

I created an example project with two interrupts for M0 and M4 as follows.

GS004717.png

And confirmed the generated source "cyfitter_sysint_cfg.h" at the interrupt configuration.

/* ARM CM0+ */

#if (((__CORTEX_M == 0) && (CY_CORE_ID == 0)))

    #define SysInt_M0__INTC_ASSIGNED 1u

    extern const cy_stc_sysint_t SysInt_M0_cfg;

#endif /* ((__CORTEX_M == 0) && (CY_CORE_ID == 0)) */

/* ARM CM4 */

#if (((__CORTEX_M == 4) && (CY_CORE_ID == 0)))

    #define SysInt_M4__INTC_ASSIGNED 1u

    extern const cy_stc_sysint_t SysInt_M4_cfg;

#endif /* ((__CORTEX_M == 4) && (CY_CORE_ID == 0)) */

It seems that the __CORTEX_M macro is used to specify the current core.

I don't know what is the CY_CORE_ID indicating.

Hi NoriakiT_91​,

Thanks for the response. Yes I can understand that __CORTEX_M is defined and it is defined in either core_cm0plus.h or core_cm4.h. But however, I would still like to know how it is included in device header file under the #if statement mentioned previously. Specifically, how (defined(__ARMCC_VERSION) && (__TARGET_ARCH_THUMB == 3)) is defined in the source code.
