Wrong FPU compiler settings.

[Pratyush]

how can i rectify this error? Am using STM32CUBE IDE and i have to link the .a libraries for further implementation. i have gone this path project properties -> c/c++ genera l-> tool settings -> MCU settings -> Floating-point ABI(-mfloat-abi=softfp) and changed. Is there any way of is there any reference to know more about FPU compiler setting.

[Radosław]

Code must have the same settings for PFU as libraries that are used.
