Merging STM32N6 Projects with .a Libraries Causing Build Errors in Keil

[saib]

Hello,

I'm working with the STM32N6570-DK board and trying to merge two example projects provided by ST:

• Project 1 (DCMIPP):
  https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/STM32N6570-DK/Applications/DCMIPP/DCMIPP_ContinuousMode 

• Project 2 (USB CDC):
  https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/NUCLEO-N657X0-Q/Applications/USBX/Ux_Device_CDC_ACM 

While merging, I added the following files from Project 1(DCMIPP) into the Project 2(USB CDC) project in Keil:

 1 . libn6-evision-awb_keil.a

 2 . libn6-evision-st-ae_keil.a

However, I’m encountering the following build issues:

• Build target 'Ux_Device_CDC_ACM'

Because of this warnings build project is failed. 

Could someone please guide me:

1. How do i add this .a files ?

Thank you in advance for your support!
