| :name: EEPROM |
| :relevant-api: eeprom_interface |
| |
| Store a boot count value in EEPROM. |
| |
| Overview |
| ******** |
| |
| This sample demonstrates the :ref:`EEPROM driver API <eeprom_api>` in a simple boot counter |
| application. |
| |
| Building and Running |
| ******************** |
| |
| In case the target board has defined an EEPROM with alias ``eeprom-0`` the |
| sample can be built without further ado. This applies for example to the |
| :ref:`native_sim` board: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/drivers/eeprom |
| :host-os: unix |
| :board: native_sim |
| :goals: run |
| :compact: |
| |
| Otherwise either a board specific overlay needs to be defined, or a shield must |
| be activated. Any board with Arduino headers can for example build the sample |
| as follows: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/drivers/eeprom |
| :board: nrf52840dk/nrf52840 |
| :goals: build |
| :shield: x_nucleo_eeprma2 |
| :compact: |
| |
| For :zephyr:board:`gd32f450i_eval` board. First bridge the JP5 to USART with the jumper cap, |
| Then the sample can be built and executed for the as follows: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/drivers/eeprom |
| :board: gd32f450i_eval |
| :goals: build flash |
| :compact: |
| |
| Sample Output |
| ============= |
| |
| .. code-block:: console |
| |
| Found EEPROM device "EEPROM_M24C02" |
| Using eeprom with size of: 256. |
| Device booted 7 times. |
| Reset the MCU to see the increasing boot counter. |
