Debian Live on Raspberry Pi4 (was: Re: I managed to get Debian Live working on the Raspberry Pi3, but it takes some tweaking)

Hi List,

here's a quick diff and explanation what's needed to build Debian Live
in a way that it works on a Pi4 as well:

Here, add:
--apt-options '--yes -oAPT::Default-Release="stable"
-oAPT::Immediate-Configure=false' \

This is because we need to add the backports-, and for now, also the
unstable-repository, yet we want to use packages from stable whenever
possible.

Replace the line above with

echo "raspi3-firmware/unstable" >>config/package-lists/raspi.list.chroot

(raspi3-firmware in unstable is a transitional package, pointing to
raspi-firmware, which contains the firmware for all Pis up to and
including the Pi4 - it would be cool if this package could hit the
backports repo $SOON...)

Now add these two lines to include the newer kernel and broadcom
firmware packages required by the Pi4:

echo "linux-image-arm64/buster-backports"
>>config/package-lists/raspi.list.chroot

echo "firmware-brcm80211/buster-backports"
>>config/package-lists/raspi.list.chroot


And finally, add these two lines to add the two repositories:

echo "deb http://deb.debian.org/debian/ unstable main contrib non-free"
> config/archives/raspi-archives.list.chroot

echo "deb http://deb.debian.org/debian buster-backports main contrib
non-free" >> config/archives/raspi-archives.list.chroot

Leave the rest of the script unchanged, run it, and you will end up with
an image that works for Pi3 and Pi4 (and probably all the other Pis as
well).

Kind Regards,
Stefan Baur
