Which generation of 3B? Which HW rev. I tested it on mine and it booted fine. Please provide more details, what image etc. Please also attach your config.txt, it it default or have you modified it?

Hardware is a Raspberry Pi 3 Model B V1.2. 

Used Fedora-Minimal-33_Beta-1.3.aarch64.raw.xz on a 32GB SD card. After several tries I ended up with applying all updates via 'sudo dnf -y update --exclude=bcm283x-firmware'. After reboot only bcm283x-firmware-20200928-2.f0eab3a.fc33.aarch64 was missing with bcm283x-firmware-20200401-1.c2c6ce8.fc33.aarch64 still installed. After running 'sudo dnf -y update' I got:

Upgrading:
 bcm283x-firmware   aarch64   20200928-2.f0eab3a.fc33   updates-testing    49 k
Installing dependencies:
 bcm2711-firmware   aarch64   20200928-2.f0eab3a.fc33   updates-testing   2.8 M
 bcm2835-firmware   aarch64   20200928-2.f0eab3a.fc33   updates-testing   3.9 M
 bcm283x-overlays   aarch64   20200928-2.f0eab3a.fc33   updates-testing    99 k

The updates applied without a problem. After reboot no output via HDMI or serial console.

/boot/efi/config.txt is the stock version without any modification:

-rwx------. 1 root root    1817 Apr  6  2020 config.txt

OK, I think the Oct 08th firmware fixes this. Booted across ARMv7/aarch64 across most devices. ARMv7: rpi2B/3B/3B+/4-4gb/4-8gb, aarch64: 3B/3B+/4-8gb. I'm not sure where my 3A+ is ATM to test that.

FEDORA-2020-884692ec02 has been submitted as an update to Fedora 33. https://bodhi.fedoraproject.org/updates/FEDORA-2020-884692ec02

Joern: Can you test this new build and let me know how you get on with it.

FEDORA-2020-884692ec02 has been pushed to the Fedora 33 testing repository.
In short time you'll be able to install the update with the following command:
`sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2020-884692ec02`
You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2020-884692ec02

See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates.

Proposed as a Blocker for 33-final by Fedora user pbrobinson using the blocker tracking app because:

 Raspberry Pi is a common platform and there was some issues with the new firmware that stopped it booting on some generations/configurations of the device. The new firmware fixes this. Because it's a boot/start issue it needs to be in the arm images so these devices will work.

Hi Peter,

Gave it another shot today without luck. Did burn a new SD card for each trial and run:

sudo dnf -y update --exclude=bcm283x-firmware
sudo reboot
sudo dnf -y upgrade

Upgraded:
  bcm283x-firmware-20201008-1.63b1922.fc33.aarch64

Installed:
  bcm2711-firmware-20201008-1.63b1922.fc33.aarch64
  bcm2835-firmware-20201008-1.63b1922.fc33.aarch64
  bcm283x-overlays-20201008-1.63b1922.fc33.aarch64

Complete!

sudo reboot

Models in use:

Raspberry Pi 3 Model A+
Raspberry Pi 3 Model B V1.2
Raspberry Pi 3 Model B+
Raspberry Pi 4 Model B, 4GB

Works only on the RPi4, not output via serial console or HDMI on the RPi3 models.

What did I do wrong? How can I further debug the issue?

BR, Joern.

Wrote Fedora-Minimal-33_Beta-1.3.aarch64.raw.xz to a 32gb MicroSD card with arm-image-installer: "sudo arm-image-installer --image=Fedora-Minimal-33_Beta-1.3.aarch64.raw.xz --target=rpi3 --media=/dev/sdd". No changes to config.txt. Ran through initial-setup, then booted into system. Rebooted to make sure the system came back up. Upon reboot (which worked), installed new firmware: "sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2020-884692ec02". Installed fine, rebooted system. System does not output via HDMI upon reboot, hangs at black screen. Waited for 5 minutes and attempted to access virtual terminals, no luck.

My above testing was performed with a RPi 3B+.

FEDORA-2020-884692ec02 has been submitted as an update to Fedora 33. https://bodhi.fedoraproject.org/updates/FEDORA-2020-884692ec02

Discussed during the 2020-10-05 blocker review meeting: [0]

The decision to classify this bug as an "AcceptedBlocker (Final)" was made as it violates the following criterion:

"All release-blocking images must boot in their supported configurations"

Installed build bcm283x-firmware-20201008-2.63b1922.fc33, tested, works for me! System boots and is usable. (RPi3B+)

Installed on RPi3A+, RPi3B and RPi3B+. All systems survived a reboot! Great, many thanks!
