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

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

-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
