Recipe for target 'flash' failed

[DMeis.1]

I am getting the following code error. The program build successfully in the simulator but when I try 'Run Target' it fails.

I use the following Build settings. And the detail log is below.

This is line 278 and 279 from the Makefile

_flash_:
	@$(st_stm32cube_programmer) -c port=SWD -d $(binary_output_path)/target.hex -el $(st_stm32cube_external_loader) -hardRst

And this is line 38 -50 of the Makefile

SOLUTION: I started a session with the wrong discovery board. It was looking for DSTM32H750 files but I have the STM32F7508-DISCO board.
