# Bootloader component

# The bootloader is not a real component that gets linked into the project.
|
|
# Instead it is an entire standalone project ( in src/) that gets built in
|
|
# the upper projects build directory. This Makefile.projbuild provides the
|
|
# glue to build the bootloader project from the original project. It
|
|
# basically runs Make in the src/ directory but it needs to zero some variables
|
|
# the SDK makefile exports first, to not let them interfere.
