[Openembedded-issues] do_package: Function failed: split_kernel_module_packages

[Damien LEFEVRE]

Hi,

I'm trying to add pixcilnx kernel object to my image based
on 4.4.38-l4t-r28.1.

The make file looks like this
----------------------------------------------------------------------------------------------------------------
obj-m := pixci.o
pixci-objs := pixcipub.o pixcilnx.o

SRC := $(shell pwd)

# invoked from user or surrogate?
all:
        ar -x pixcilnx_aarch64_4.4.a pixcilnx_4.4.o
        mv pixcilnx_4.4.o pixcilnx.o_shipped
        $(MAKE) -C $(KERNEL_SRC) M=$(SRC)
        $(CROSS_COMPILE)strip --strip-debug --discard-all pixci.ko

modules_install:
        $(MAKE) -C $(KERNEL_SRC) M=$(SRC) modules_install

clean:
        rm -f *.o
        rm -f *.ko
        rm -f .pixci.mod.o.cmd
        rm -f .pixci.o.cmd
        rm -f .pixci.ko.cmd
        rm -f .pixcipub.o.cmd
        rm -rf .tmp_versions
----------------------------------------------------------------------------------------------------------------


The pixci.bb file looks like this

----------------------------------------------------------------------------------------------------------------
SUMMARY = "Kernel module for EPIX grabber"
#TODO: set correct license
LICENSE = "CLOSED"

inherit module

SRC_URI = "file://Makefile \
           file://pixcilnx_aarch64_4.4.a \
           file://pixcipub.c \
           file://pixcipub.h \
          "

S = "${WORKDIR}"

# The inherit of module.bbclass will automatically name module packages with
# "kernel-module-" prefix as required by the oe-core build environment.

KERNEL_MODULE_AUTOLOAD += "pixci"
#This should put your module name into /etc/modules-load.d/modname.conf on
the image.
----------------------------------------------------------------------------------------------------------------


Do package fails with the following error:

Any ideas what I could be doing wrong?
