question about customize rootfs by using mergefiles

[misakamikoto]

Hi All:

    follow the step by what user guide metioned,just add my own file in meta-fsl-arm/recipes-extended/merge-files/merge-files/merge/usr/bin/* then make image.and I found my file in /home/root/usr/bin.How can change it to /usr/bin not /home/root/usr/bin.I notice merge-files_1.0.bb do it like this:

find ${WORKDIR}/merge/ -maxdepth 1 -mindepth 1 -not -name README

    -exec cp -fr '{}' ${D}/${MERGED_DST}/ \;

So should I change MERGED_DST value or you all have some more effictive solution？

Your message contains the following:

Check the architecture and endiannes of the binary
0028: if not ((machine == elf.machine()) or \
0029: ((("virtual/kernel" in provides) or bb.data.inherits_class("module", d) ) and (target_os == "linux-gnux32"))):

Check the architecture and endiannes of the binary.

Have a great day,

Do you use the similar command sequence?

1.            How do I view the content of rootfs?

The expanded list of rootfs content is contained in the <IMAGE_ROOTFS>.

Note: Use bitbake -e <rootfs-name> | grep ^IMAGE_ROOTFS= to get the value of <IMAGE_ROOTFS>.

2.            How do I display the packages included in the current rootfs image?

There are two methods:

a.            $ bitbake -e <image-target> | grep IMAGE_INSTALL

b.            $ bitbake -g <image-target>

3.            How do I add a pre-built binary into the rootfs?

Do the following:

a.            $ cd <yocto_install_path>/meta-fsl-networking/recipes-extended/merge-files

b.            Copy the files into files/merge, e.g. put bash into files/merge/usr; bash will be included in usr/ of the new rootfs.

c.            Edit rootfs recipe (e.g. fsl-image-flash.bb) to add merge-files in IMAGE_INSTALL variable.

d.            Build new rootfs image: $ bitbake <rootfs-target> (e.g. fsl-image-flash)

4.            Can you give an example of using dtc to reverse to a dts from a dtb?

Do the following:

a.            $ export PATH=<path-of-dtc>:$PATH

b.            $ dtc -I dtb -O dts -o name-of-dts name-of-dtb

3.            How do I add a pre-built binary into the rootfs?

Do the following:

a.            $ cd <yocto_install_path>/meta-fsl-ppc/recipes-extended/merge-files

b.            Copy the files into files/merge, e.g. put bash into files/merge/usr; bash will be included in usr/ of the new rootfs.

c.            Edit rootfs recipe (e.g. fsl-image-minimal.bb) to add merge-files in IMAGE_INSTALL variable.

d.            Build new rootfs image: $ bitbake fsl-image-minimal

In the above step 3->b , when I added a .ko(kernel loadable module) file or a folder containing files is added into <yocto_install_path>/meta-fsl-ppc/recipes-extended/merge-files/merge-files/merge, and subsequent running of 'bitbake fsl-image-minimal' , I get the following error -

However, when a simple txt file(temp.txt) is added to <yocto_install_path>/meta-fsl-ppc/recipes-extended/merge-files/merge-files/merge, 'bitbake fsl-image-minimal' run successfully.
