Hi,
I'm developing code for the nrf5340 network core. I am including the file ../nordic_bsp/modules/nrfx/mdk/nrf5340_network.h in one of my source files. This file has the following:
#define __DSP_PRESENT 0 /*!< DSP present or not
When I build, I get the following error and the build aborts:
../../../thirdparty/nordic-bsp/components/toolchain/cmsis/include/core_cm33.h:146:8: error: #error "Compiler generates DSP (SIMD) instructions for a devices without DSP extensions (check __DSP_PRESENT)" 146 | #error "Compiler generates DSP (SIMD) instructions for a devices without DSP extensions (check __DSP_PRESENT)"
Looking at core_cm33.h:
#if defined ( __CC_ARM )
#if defined (__TARGET_FPU_VFP)
#if defined (__FPU_PRESENT) && (__FPU_PRESENT == 1U)
#define __FPU_USED 1U
#else
#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"
#define __FPU_USED 0U
#endif
#else
#define __FPU_USED 0U
#endif
#if defined (__ARM_FEATURE_DSP) && (__ARM_FEATURE_DSP == 1U)
#if defined (__DSP_PRESENT) && (__DSP_PRESENT == 1U)
#define __DSP_USED 1U
#else
#error "Compiler generates DSP (SIMD) instructions for a devices without DSP extensions (check __DSP_PRESENT)"
#define __DSP_USED 0U
#endif
#else
#define __DSP_USED 0U
#endif
So the test for __DSP_PRESENT correctly determines that it is not so why does it throw an error? This surely is normal, not an error.
Any advice would be appreciated.
Regards,
AC
