SWSTM32 Ac6 toolchain linker error

Hi all,

After building a project for the STM32F469xx processor I get a bunch of the following linker errors:

<project_name>cubemx.elf uses VFP register arguments, <file_name>.o does not exist?

failed to merge target specific data of file <file_name>.o?

My MCU Settings are:

prefix: arm-none-eabi

Floating point hardware: fpv4-sp-d16

Floating point-ABI: hard

Instruction set: Thumb 2


library: cmath


My question is what causes this linker error, and what steps do I have to take to resolve this?

Any help I will appreciate!
