Dear Yocto team,

We have developed some recipe file to install  the firmware binary in the file system of Yocto.

Recipe file is working fine in Yocto morty version but when we tried the same in the Yocto sumo version we got the following error for bitbake core-image-minimal.

ERROR: core-image-minimal-1.0-r0 do_rootfs: No manifest generated from: rtl-firmware in /home/graco_sm/1.4.4/GRACO_SM_REL_V1.1/Software/U-Boot-and-Linux/sumo/poky/meta-graco/recipes-graco/firmware/rtl-firmware.bb

Recipe file rtl-firmware.bb content

DESCRIPTION = "RTL 8723BU BT firmware"

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COREBASE}/LICENSE;md5=4d92cd373abda3937c2bc47fbc49d690"

PACKAGE_ARCH = "all"

SRC_URI += " \
    file://rtl8723b_fw.bin \
"

do_install () {
    install -d ${D}${base_libdir}/firmware/
    install -m 755 ${WORKDIR}/rtl8723b_fw.bin ${D}${base_libdir}/firmware/
}

FILES_${PN} += " \
        ${base_libdir}/firmware/rtl8723b_fw.bin \
"

What needs to be done for to avoiding manifest error  ?

Kindly help us to resolve this issue.

Thanks and Regards,
