Hi all,

An update for those interested:

brcmfmac43430-sdio.bin is provided by:

openembedded-core/meta/recipes-kernel/linux-firmware/linux-firmware_git.bb:530:

brcmfmac43430-sdio.txt is provided by:

recipes-kernel/linux-firmware/.linux-firmware_%.bbappend.swp

So I renamed my bbappend to match the file in meta-raspberry-pi. And these are the contents:

--------------------------------------------------------------------------------

SRCREV_linuxfirmware = "a61ac5cf8374edbfe692d12f805a1b194f7fead2"

SRCREV_recalboxbuildroot = "f648e4b54eb5e4be593746d6cc51375b22a7efbd"

SRC_URI += "git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git;nobranch=1;destsuffix=${S}/git1;name=linuxfirmware \

git://github.com/recalbox/recalbox-buildroot.git;protocol=https;nobranch=1;destsuffix=${S}/git2;name=recalboxbuildroot "

LIC_FILES_CHKSUM += "file://git1/LICENCE.broadcom_bcm43xx;md5=3160c14df7228891b868060e1951dfbc \

file://git2/COPYING;md5=e4edbc78b8892db416b6a07e0d97309a "

do_install_append() {

install -d ${D}${base_libdir}/firmware

install -d ${D}${base_libdir}/firmware/brcm

cp -rfv git1/brcm/brcmfmac43430-sdio.bin ${D}${base_libdir}/firmware/brcm

cp -rfv git2/board/warp7/rootfs_overlay/lib/firmware/brcm/brcmfmac43430-sdio.txt ${D}${base_libdir}/firmware/brcm

}

FILES_${PN}-bcm43430 += " \

${base_libdir}/firmware/brcm/brcmfmac43430-sdio.bin \

${base_libdir}/firmware/brcm/brcmfmac43430-sdio.txt \

--------------------------------------------------------------------------------

But that errors out with this garbles mess:

--------------------------------------------------------------------------------

ERROR: ExpansionError during parsing /linaro/mbl/workspace-arm/build-mbl/conf/../../layers/openembedded-core/meta/recipes-kernel/linux-firmware/linux-firmware_git.bb

--------------------------------------------------------------------------------

I'm guessing t's really not happy about me providing a git repo and messing up its refs.

So, just to test things, I hacked my recipe to match the RPi one and copied the files I want locally into a "files" subdir. My recipe now looks like this:

--------------------------------------------------------------------------------

SRC_URI += " \

file://brcmfmac43430-sdio.bin \

file://brcmfmac43430-sdio.txt \

do_install_append() {

install -d ${D}${base_libdir}/firmware

install -d ${D}${base_libdir}/firmware/brcm

install -m 0644 $_firmware ${WORKDIR}/brcmfmac43430-sdio.bin ${D}${base_libdir}/firmware/brcm

install -m 0644 $_firmware ${WORKDIR}/brcmfmac43430-sdio.txt ${D}${base_libdir}/firmware/brcm

}

FILES_${PN}-bcm43430 += " \

${base_libdir}/firmware/brcm/brcmfmac43430-sdio.bin \

${base_libdir}/firmware/brcm/brcmfmac43430-sdio.txt \

--------------------------------------------------------------------------------

It gives me this warning from meta-raspberrypi's linux-firmware_%.bbappend:

WARNING: linux-firmware-1_0.0+gitAUTOINC+bf04291309-r0 do_install: linux-firmware stopped providing brcmfmac43430 v7.45.41.26.

... but otherwise, it build. However, I still end up with the files from meta-raspberrypi in the build. So I guess that was a pointless exercise.

Cheers.,

Ryan.

It is most likely a subpackage of the linux-firmare recipe.
