Source: linux Version: 5.17.3-1 Severity: important X-Debbugs-Cc: raspi-firmw...@packages.debian.org
Hi, In the process of testing patches for the Raspberry Pi Compute Modules (CM3 and CM4), for bullseye[1][2] and bookworm[2], I discovered that bookworm images don't boot on the CM4. 1. https://bugs.debian.org/1010317 2. https://bugs.debian.org/996937 The usual start-up rainbow is displayed, the screen turns to black and nothing happens. My first stop was trying to downgrade the bootloader (shipped by the raspi-firmware package) to the bullseye's version, but that didn't help. Then I moved to starting from a bullseye image (which boots), upgrading the raspi-firmware package, that still boots. Then I deployed 5.16.18-1 (from snapshot.debian.org), that still boots. Then I deployed 5.17.3-1, and it broke booting. I'll try and pinpoint when it broke using the various intermediary versions: - 5.17~rc3-1~exp1 - 5.17~rc4-1~exp1 - 5.17~rc5-1~exp1 - 5.17~rc6-1~exp1 - 5.17~rc7-1~exp1 - 5.17~rc8-1~exp1 - 5.17.1-1~exp1 and then try to figure out what broke exactly. Contrary to my earlier efforts to introduce support for that hardware a few months ago, I haven't been following upstream changes recently, so I'll need to catch up.
