EEPROM
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
Native simulator - native_sim board:
west build -b native_sim samples/drivers/eeprom
west build -t run
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:
west build -b nrf52840dk/nrf52840 --shield x_nucleo_eeprma2 samples/drivers/eeprom
For 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:
west build -b gd32f450i_eval samples/drivers/eeprom
west flash
Sample Output
Found EEPROM device "EEPROM_M24C02"
Using eeprom with size of: 256.
Device booted 7 times.
Reset the MCU to see the increasing boot counter.
