mbed-os-examples
NVStore example for Mbed OS. This is an example of an application that uses the NVStore APIs. The application invokes the NVStore APIs and prints the results after each such invocation.
Required hardware
- An [FRDM-K64F](http://os.mbed.com/platforms/FRDM-K64F/) development board.
- A micro-USB cable.
# Other hardware
Although the board shown in this examples is K64F, the example should work on any Mbed enabled hardware supporting the internal flash driver (has "FLASH" in the "device_has" in targets/target.json file).
Getting started
1. Import the example.
``` mbed import mbed-os-example-nvstore cd mbed-os-example-nvstore ```
2. Keep the default NVStore configuration, which uses the last two sectors (4KB each) as NVStore areas.
3. Compile and generate binary.
For example, for `GCC`:
``` mbed compile -t GCC_ARM -m K64F ```
4. Open a serial console session with the target platform using the following parameters:
- Baud rate: 115200
- Data bits: 8
- Stop bits: 1
- Parity: None
5. Copy the application `mbed-os-example-nvstore.bin` in the folder `mbed-os-example-nvstore/BUILD/<TARGET NAME>/<PLATFORM NAME>` onto the target board.
6. Press the RESET button on the board to run the program
7. The serial console should now display a series of results following the NVStore API invocations.
8. Now copy `mbed_app-8KB-areas.json` to `mbed_app.json`. This should use 8KB areas (two pairs of last sectors) as NVStore areas.
9. Repeat steps 3-7. Notice the changes in prints of area addresses and sizes and with the amount of possible keys this configuration can hold.
10. To restore the default configuration, copy `mbed_app-default-areas.json` to `mbed_app.json`.
