The rpi-eeprom-update is a command-line tool used to update the EEPROM (Electrically Erasable Programmable Read-Only Memory) on Raspberry Pi computers. The EEPROM is a small piece of memory that stores firmware code and configuration information for the Raspberry Pi’s system-on-chip (SoC).
Updating the EEPROM is important because it can improve the performance and stability of the Raspberry Pi, as well as fix any bugs or security vulnerabilities that may be present in the current firmware.
The rpi-eeprom-update tool can be used to view information about the current firmware version, as well as update the firmware to the latest version available. To use the rpi-eeprom-update tool, you need to have the tool installed on your Raspberry Pi. The tool is usually included in the Raspberry Pi OS distribution and can be updated using the standard package management tools.
It is important to note that updating the EEPROM can be risky and may result in the loss of data or even damage to the hardware. Therefore, it is recommended to backup any important data before proceeding with the update.
rpi-eeprom-update Command Examples
