rpi-eeprom-update [options]... [FILE]
|
|
Checks whether the Raspberry Pi bootloader and the VL805 USB controller
|
|
EEPROMs are up-to-date and optionally updates the EEPROMs at the next reboot.
|
|
|
|
The default update mechanism writes recovery.bin and the EEPROM update
|
|
image(s) (pieeprom.upd and vl805.bin) to the boot partition on the sd-card.
|
|
The SHA256 hash of the corresponding images are written to pieeprom.sig
|
|
and/or vl805.sig. This guards against file system corruption which could
|
|
cause the EEPROM to be flashed with an invalid image. This is is not a
|
|
security check.
|
|
|
|
At the next reboot the ROM runs recovery.bin which updates EEPROM(s).
|
|
If the update was successful recovery.bin renames itself to recovery.000
|
|
to prevent it from running a second time then resets the system.
|
|
The system should then boot normally.
|
|
|
|
If /boot does not correspond to the boot partition on the sd-card and this
|
|
is not a NOOBS system then the mount point for BOOTFS should be defined
|
|
in /etc/default/rpi-eeprom-update by defining the BOOTFS variable.
|
|
|
|
For reference, the flashrom update mechanism may be enabled by defining
|
|
USE_FLASHROM=1 in /etc/default/rpi-eeprom-update. This not recommended
|
|
because the SPI pins are muxed with audio and other device drivers may
|
|
be using SPI (e.g. HATs). This is also not safe in the event of a power
|
|
failure during the update of the EEPROM.
|
|
|
|
A backup of the current EEPROM config file is written to ${FIRMWARE_BACKUP_DIR}
|
|
before applying the update.
|
|
|
|
-a Automatically install bootloader and USB (VLI) EEPROM updates.
|
|
-A Specify which type of EEPROM to automatically update (vl805 or bootloader)
|
|
-d Use the default bootloader config instead of migrating the current settings
|
|
-f Install the given file instead of the latest applicable update
|
|
Ignores the FREEZE_VERSION flag in bootloader and is intended for manual
|
|
firmware updates.
|
|
WARNING: This command should only be run from console mode in order to
|
|
avoid conflicts/deadlock with dtoverlay/dtparam settings.
|
|
-h Display help text and exit
|
|
-i Ignore package checksums - for rpi-eeprom developers.
|
|
-j Write status information using JSON notation
|
|
-m Write status information to the given file when run without -a or -f
|
|
-r Removes temporary EEPROM update files from the boot partition.
|
|
-u Install the specified VL805 (USB EEPROM) image file.
|
|
|
|
To extract the configuration file from an EEPROM image:
|
|
rpi-eeprom-config pieeprom.bin --out bootconf.txt
|
|
|
|
To update the configuration file in an EEPROM image:
|
|
rpi-eeprom-config pieeprom.bin --config bootconf.txt --out pieeprom-new.bin
|
|
|
|
To flash the new image:
|
|
sudo rpi-eeprom-update -d -f ./pieeprom-new.bin
|
|
|
|
The syntax is the same as config.txt but section filters etc are not supported. See
|
|
online documentation for the list of parameters.
