    BSEC library for Cortex-M7 with -mfloat-abi=softfp

    Hello,

    We use BME680 sensor and a ARM Cortex M7 (STM32H743) as MCU. We're struggling to compile our project with given BSEC library file with FPU option -mfloat-abi=softfp (Mix HW/SW inplementation).

    The library for Cortex-M7 you released in SW package works with -mfloat-abi=hard only.

    Could you please support us with this library?

    Best regards,

    NH

    In order to forward your request to our BSEC team, could you please confirm which of the supported compilers are you currently using in your project?

    Hi,

    Thanks for feedback. We use GCC as compiler.

    Hello,

    For more accurate, we're using below project settings for GCC:

    -mfpu=fpv5-d16 -mfloat-abi=softfp

    Thanks,

    NH
