GPU memory split behavior change on 64-bit Raspberry Pi OS
Documented behavior shift The Raspberry Pi 4's gpu_mem parameter in /boot/config.txt has historically controlled the GPU/CPU memory split on 32-bit Raspberry Pi OS, with values such as 256 MB being honored directly. Starting with the 64-bit Raspberry Pi OS (Bullseye and later) and bootloader firmware 2022.02, a new gpu_mem_256 flag was introduced that appear
raspberrypiBoot partition not found: capturing early-boot diagnostics without serial console
When a Raspberry Pi fails to mount the boot partition during SD-card boot, the kernel never starts and no logs are written to the filesystem. The bootloader emits diagnostic messages only on the serial console (ttyAMA0 or ttyS0), which requires a USB-to-serial adapter and an active capture session at power-on. Without that hardware, the only visible symptom
tryboot automatic rollback behavior after failed kernel upgrade
Uncertainty around tryboot rollback capability The Raspberry Pi bootloader's tryboot feature (introduced in 2022) allows switching between two bootloader configurations, but its ability to automatically roll back a failed kernel or firmware update remains unclear. The mechanism requires a pre-staged alternate boot partition and manual intervention to activat

linuxnixos-rebuild boot and default boot entry persistence
Generation Switching and Bootloader Defaults NixOS manages system states through generations, allowing users to activate new configurations via nixos-rebuild switch or prepare them for the next restart using nixos-rebuild boot . While switch handles immediate activation, boot is intended to make a generation available for the next boot cycle without applying
