Below is an example package .mk file for a kernel module. It uses the GENTARGETS infrastructure to explicitly specify the commands that should be executed when building and installing. Depending on the organization of EtherCAT, it may be a good idea to create two packages: one for the application and one for the kernel modules. It will probably make the .mk files a tad simpler. FOOMODULE_VERSION = 0.1.2 FOOMODULE_SOURCE = foomodule-$(FOOMODULE_VERSION).tar.gz FOOMODULE_SITE = http://yoursite FOOMODULE_DEPENDENCIES = linux FOOMODULE_INSTALL_MOD_DIR = foo define FOOMODULE_BUILD_CMDS $(MAKE) $(LINUX_MAKE_FLAGS) -C $(LINUX_DIR) M=$(@D) modules endef define FOOMODULE_INSTALL_TARGET_CMDS $(MAKE) $(LINUX_MAKE_FLAGS) -C $(LINUX_DIR) M=$(@D) \ INSTALL_MOD_STRIP=1 \ INSTALL_MOD_DIR=$(FOOMODULE_INSTALL_MOD_DIR) \ modules_install endef define FOOMODULE_UNINSTALL_TARGET_CMDS rm -rf $(TARGET_DIR)/lib/modules/$(LINUX_VERSION_PROBED)/$(FOOMODULE_INSTALL_MOD_DIR) endef $(eval $(call GENTARGETS)) Documentation on adding packages is available here: http://buildroot.uclibc.org/buildroot.html#add_packages If the EtherCAT application uses autotools (i.e. when it has files like configure.in, configure.ac, Makefile.in, Makefile.am) then you can use the AUTOTOOLS infrastructure for that part. The modules should be done with GENTARGETS. Best regards, Thomas
