说明
rpi-eeprom-update manages the bootloader EEPROM firmware on Raspberry Pi 4, 400, Compute Module 4, and Pi 5 models. The EEPROM contains the boot code that initializes the system before the operating system loads, including USB boot, network boot, and NVMe boot support. Firmware images are provided in /lib/firmware/raspberrypi/bootloader/ under release channels: critical (rarely updated, highest stability), stable (default, recommended), beta (new features, less tested), and latest (most recent). Updates improve boot reliability, add features like new boot modes, and fix bugs in the low-level boot firmware.
