i fix espboot aplication.
just replace /espMCUME/espboot/main/component.mk

This Makefile can be left empty. By default, it will take the sources in the
src/ directory, compile them and link them into lib(subdirectory_name).a
in the build directory. This behaviour is entirely configurable,
please read the ESP-IDF documents if you need to do this.
