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
sample can be built without further ado. This applies for example to the
Native POSIX execution (native_posix) board:
west build -b native_posix 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 samples/drivers/eeprom -- -DSHIELD=x_nucleo_eeprma2
Found EEPROM device "EEPROM_M24C02" Using eeprom with size of: 256. Device booted 7 times. Reset the MCU to see the inceasing boot counter.
