This page provides links to the production and development release images for the bootloader EEPROM on BCM2711-based Raspberry Pi computers. Normally, the bootloader is automatically updated after an APT update via the rpi-eeprom-update utility.
Release notes are available here.
The default production EEPROM image release is 2022-11-25 and can be installed via the Raspberry Pi Imager.
Please see the USB mass storage boot guide. For support or hardware interoperability discussions please use the Raspberry Pi general discussion forum.
Old bootloader images are periodically removed from the APT package to reduce the disk space, but are still available via Github here.
Old releases may fail to boot on newer hardware revisions.
