FIRMWARE_RELEASE_STATUS
Specifies the release status of the firmware to apply. The default is 'critical'.
Specifies the release status of the firmware to apply.
Before selecting a firmware release directory this script checks whether there
is a board revision specific variant e.g. critical-c03111. If present then the
is a board revision specific variant e.g. default-c03111. If present then the
board-revision specific version is used in preference.
Release status:
Bootloader releases follow a pipeline where images are released to the 'beta'
directory first. The binaries are then promoted to 'latest' and finally 'default'
so the 'default' binary is always the most tested release.
critical: The latest production release plus important security or hardware compatibility bug fixes.
default:
The default bootloader image which is updated once new features in
'latest' are stable or for critical hardware or security updates.
stable: Contains new features that have already undergone some beta testing.
These are candidates for new production releases.
Raspberry Pi OS automatically updates the bootloader when a newer 'default' image
is available following an APT update to the rpi-eeprom package.
beta: New features, bug fixes for development/test purposes. Use at your own
risk!
latest:
Contains the latest features which have undergone testing via the 'beta'
release. The configuration parameters are stable.
beta:
Contains experimental features and bug fixes. Configuration parameters may
change in subsequent 'beta' releases.
As far as rpi-eeprom-update is concerned FIRMWARE_RELEASE_STATUS is just
the subdirectory mapping under ${FIRMWARE_ROOT}. Therefore, custom release
directories are supported by creating the relevant directory and changing
the FIRMWARE_RELEASE_STATUS environment variable.
The 'default' and 'latest' release names are symlinks to the old directory
names of 'critical' / 'stable'.

To extract the configuration file from an EEPROM image:
rpi-eeprom-config pieeprom.bin --out bootconf.txt
