VFP register arguments on STM32L4R5ZI System workbench

When I compile the STM32L4R5ZI BME680 libary, I got the error message of use VFP register arguments,

Can anyone let me know how to fix  inside the AC6 SW workbench?

Thanks

-mfloat-abi=soft -mfpu=fpv4-sp-d16 -L worked and got build but 

Now its failing in SystemClock_Config.

And entering to WWDG_IRQHandler() at startup_stm32l4r5xx.s:132 0x8009dc0

Failing at 

if(HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_4) != HAL_OK)

{ /* Initialization Error */ _Error_Handler(__FILE__, __LINE__); }

Thanks

You'd need to determine the settings for the FPU used in the library

-mfpu=fpv4-sp-d16 -mfloat-abi=hard

If hard doesn't match, try the soft ABI setting, or NOT using the FPU

It's complaining it is mis-matched, work through the FPU setting options if you can't tell from inspecting the library

Try different combinations of the float configuration flags

-msoft-float

,

-mfloat-abi={soft,softfp}

Make sure to a) clear the structures defined locally, and b) that the PLL_M parameter is correctly programmed on L4 platforms
