Hi Zoran, Thanks, I modified the Makefile:
obj-m := huawei_cdc_ncm.o Kconfig (obj-y := huawei_cdc_ncm.o) SRC := $(shell pwd) all: $(MAKE) -C $(KERNEL_SRC) M=$(SRC) modules_install: $(MAKE) -C $(KERNEL_SRC) M=$(SRC) modules_install clean: rm -f *.o *~ core .depend .*.cmd *.ko *.mod.c rm -f Module.markers Module.symvers modules.order rm -rf .tmp_versions Modules.symvers but this is the error: ERROR: huawei-1.1-r0 do_configure: oe_runmake failed ERROR: huawei-1.1-r0 do_configure: Function failed: do_configure (log file is located at /home/kerenyiz/oe-core/build/tmp-glibc/work/barix_ipam400-oe-linux-gnueabi/huawei/1.1-r0/temp/log.do_configure.4488) ERROR: Logfile of failure stored in: /home/kerenyiz/oe-core/build/tmp-glibc/work/barix_ipam400-oe-linux-gnueabi/huawei/1.1-r0/temp/log.do_configure.4488 Log data follows: | DEBUG: Executing shell function do_configure | NOTE: make KERNEL_SRC=/home/kerenyiz/oe-core/build/tmp-glibc/work-shared/barix-ipam400/kernel-source clean | ERROR: oe_runmake failed | Makefile:2: *** empty variable name.
