/boot is moving to /boot/firmware

[lurch]

So all references to /boot/config.txt and /boot/cmdline.txt will need updating to /boot/firmware/config.txt, /boot/firmware/cmdline.txt, etc. etc.

EDIT: But only for Bookworm, Bullseye will continue to use /boot/config.txt, /boot/cmdline.txt etc.

@nathan-contino For bookworm labelled issues you'll need to check out the bookworm branch and work on there. Both @lurch and @jehlers42 are also working on the branch for push/pull as you go rather than waiting to do big commits otherwise you're going to run into merge conflicts.

Hi @lurch @aallan
Thank you for the update.

I've downloaded the 64-bit RPiOS 'Bookworm' from here: https://raspi.debian.net/tested-images/
Below are the environment details:

root@rpi4-20230612:/boot# cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

root@rpi4-20230612:/boot# uname -a
Linux rpi4-20230612 6.1.0-9-arm64 #1 SMP Debian 6.1.27-1 (2023-05-08) aarch64 GNU/Linux
root@rpi4-20230612:/boot# 

I've noticed that there's no configuration-related content in the /boot/firmware/config.txt file. It only contains the following details:

root@rpi4-20230612:/boot/firmware# cat config.txt
# Do not modify this file!
#
# It is automatically generated upon install or update of either the
# firmware or the Linux kernel.

# If you need to set boot-time parameters, do so via the

# /etc/default/raspi-extra-cmdline files.

I'm interested in modifying the RP4 configuration via the config.txt file that is mention in below:
We've successfully configured all of these operations on the Buster Raspi 32-bit OS.

Could you kindly advise where I can locate this information in Bookworm?

I've downloaded the 64-bit RPiOS 'Bookworm' from here: https://raspi.debian.net/tested-images/

That isn't Raspberry Pi OS, that's a stock Debian image.

[fti-sfuke]

@aallan Thanks for reply.

Raspberry Pi OS Debian12 ( Bookworm ) is not yet available on the official Raspberry Pi website (https://www.raspberrypi.com/software/operating-systems/).

And I have been unable to found a Raspberry Pi OS Debian 12 testing image.
Could you kindly provide guidance on where I might obtain it? or should I wait for official Raspberry Pi OS release ?

Is it not possible to achieve the above-mentioned operations on a stock Debian image?

We are currently working internally towards a Bookworm release for Raspberry Pi.

It is not yet available publically.

That's a question for the maintainers of the image you're using 🙂

Raspberry Pi OS is based on Debian, but with many changes; in a similiar way that Ubuntu is based on Debian, but with many changes.

[lurch]

Reopening, because of #3105 (comment)

[lurch]

Thanks @nathan-contino

[flatsiedatsie]

Out of curiosity: why was this done/needed? It's causing a lot of work to fix hardcoded references to /boot/ .

[JamesH65]

I believe its an upstream Debian change.

[ncopa]

I believe its an upstream Debian change.

Do you have any references on why upstream debian did this change?

EDIT: found some good references. Apparently upstream debian believe downstream Raspbian broke things:

how to edit config.txt ?
/boot/firmware/config.txt -> i edited but it not working

[lurch]

@hhlocsync It sounds like your question is better suited to the forums https://forums.raspberrypi.com/
