The next Beagle is here, BeaglePlay!

I have tried as

fdtoverlays /boot/overlays/k3-am625-beagleplay-bcfserial-no-firmware.dtbo
and
fdtoverlays /overlays/k3-am625-beagleplay-bcfserial-no-firmware.dtbo

but seems to make no difference. I can see the file is there in /boot/firmware/overlays but dont see any mention of it via beagle-version or dmesg…hmmm…

Is there something one must do to “activate” an overlay after editing extlinux.conf?

Anyway maybe thats a red-herring anyway because I can see bcfserial module is loaded…

Hi @BarryBeagle , what kernel version (uname -r)

I’d say, apt update/upgrade, after the board went public more private changes got merged to public repo’s…

Regards,

One thing that occurs to me is I did a git pull in /opt/source in order to apply the fix to enable R4F remoteproc. Perhaps it has something to do with that??

Where is /boot/UEnv.txt on the Play?

–Mark

25

It’s under: /boot/firmware/extlinux/extlinux.conf

Thanks @RobertCNelson , but I don’t see how to tell it which image to boot from.

i know you like to customize… extlinux.conf supports a similar menu system like grub, so you can list multiple kernel options.

Sadly since we only store the active kernel under /boot/firmware/ for u-boot to operate on. To swap kernel’s you will need to manually do what is shown in /etc/kernel/postinst.d/zz-uenv_txt or just install the linux-image*deb and this will auto run:

if [ -f /boot/firmware/extlinux/extlinux.conf ] ; then
        if [ -f /boot/vmlinuz-${version} ] ; then
                rm -f /boot/firmware/Image || true
                cat /boot/vmlinuz-${version} | gunzip -d > /boot/firmware/Image
                cp -v /usr/lib/linux-image-${version}/ti/k3-*.dtb /boot/firmware/ || true
                rm -f /boot/firmware/initrd.img || true
                cp -v /boot/initrd.img-${version} /boot/firmware/initrd.img || true
                if [ -d /usr/lib/linux-image-${version}/ti/overlays/ ] ; then
                        mkdir -p /boot/firmware/overlays/ || true
                        cp -v /usr/lib/linux-image-${version}/ti/overlays/*.dtbo /boot/firmware/overlays/ || true
                fi
                echo "zz-uenv_txt: Updated extlinux.conf /boot/firmware/ for: [${version}]"
        fi
fi

Hi,
Where can I find video output OLDI (LVDS) test setup/plan and results?
Thanks
