Build error when building from template

[DGIL-BEZARES]

Hello,

I have cloned this repository as a submodule of my own repository to have a setup customized to my board.

The problem is that whenever I try to build this using make I get this message:

$ make

make: *** [../rules.mk:131: bin/main.o] Error 1

However, I have tried running the examples from the example repo without trouble.

The only change I made was renaming the my-project.c file to main.c and updating the Makefile accordingly

I hope you can point me in the right direction.
