I was unable to duplicate the behavior you've documented. I was able to run make and build the entire demo (output file was build/freertos_tcp_mps2_demo.axf). I was able to execute make startup.d to trigger the makefile target without your changes. Make was able to successfully build the startup.d file.

When viewing the contents with cat startup.d I saw the following output:

startup.o startup.d : startup.c \

Can you provide more details on your setup and the exact commands you ran which caused the failure?

When I pull your changes I get the following error when running make startup.d:

make: *** No rule to make target `startup.d'.  Stop.
