Reto Schneider 1c1801ee7f drivers: eeprom: Fix format strings Building for native_posix_64 exposes faulty format strings. Changes in this commit also ensure that the shell code gets built in CI, thus this kind of problem can not be introduced again later on.

EEPROM Sample
#############

Overview
********

This sample demonstrates the EEPROM driver 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_posix` board:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/eeprom
   :host-os: unix
   :board: native_posix
   :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 :ref:`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.
