Detailed Description

Test case to demonstrate each API function works correctly.

Example 5 Notes

This flash-journal synchronous mode example test does the following CFSTORE operations:

• initialises
• creates a key-value pair (KV).
• writes the data for the KV
• closes KV.
• flushes the KV to flash
• flushes the KV to flash again
• uninitialises
• initialises
• opens KV for reading.
• deletes KV
• closes KV.
• flushes the updated state to flash to store the removal of the deleted KV.
• uninitialises
• stops

This test is coded so as to work only in flash journal sync mode i.e. with caps.asynchronous_ops == false

The test leaves the flash in the same state as at the beginning of the test so it can be run a second time on the device without flashing, and the test should still work.

How to Build Example5 as a Stand-alone Application

This example can be build as a stand-alone application as follows:

• Create a new mbed application using the `mbed new .` command.
• Copy this file example5.cpp from the to the top level application directory and rename the file to main.cpp.
• Build the application with `mbed compile -v -m <target> -t <toolchain> -DCFSTORE_EXAMPLE5_APP` e.g. `mbed compile -v -m K64F -t GCC_ARM -DCFSTORE_EXAMPLE5_APP`.
