Toolchain for m0054-data-fs.ext4

Rowan Dempster

Hi Modal,

I'm looking into adding some data in the m0054-data-fs.ext file system. I'm having some trouble getting the voxl2 to work correctly when I try to add the data and then create a new Android sparse image that I flash instead of m0054-data-fs.ext. Would it be possible to provide me with the tools used to create that m0054-data-fs.ext file system at ModalAI so that I can use the exact same tools to create the sparse android image after adding my files to it?

Thank you,
Rowan

I found https://gitlab.com/voxl-public/system-image-build/meta-voxl2/-/blob/qrb5165-ubun1.0-14.1a/recipes-products/image/qti-ubuntu-robotics-image.bbappend#L148, which is in bitbake language (not familiar)?

Is

do_makeuserdata() {
    make_ext4fs -s -l ${USERDATA_SIZE_EXT4} ${IMAGE_EXT4_SELINUX_OPTIONS} \
        -a /data -b 4096 ${DEPLOY_DIR_IMAGE}/${OVERLAYIMAGE_TARGET} ${IMAGE_ROOTFS}/data
}

something I could do just on normal ubuntu in CI? I'm thinking to build a cleo-specific userdata in CI with all of our custom software.

What are ${IMAGE_EXT4_SELINUX_OPTIONS}, is there some secret sauce there?
