Run common NVM driver unit tests.

Initializes the clock system, board, serial output and NVM, then sets up the NVM unit test suite and runs it.

static void run_buffer_access_test ( const struct test_case *  test )

static

Test the read and write buffer operations on the NVM.

This function will test the read and write functionalities of the NVM using buffer access. It will first fill a buffer with a known pattern and read it back by testing each value read.

Parameters

test	Current test case.

static void run_byte_access_test ( const struct test_case *  test )

static

Test the read and write byte operations on the NVM.

This function will test the read and write functionalities of the NVM using byte access. It will first write a known pattern on the 2 consecutive addresses and read it back by testing each value read.

Parameters

test	Current test case.

static void run_memory_check_test ( const struct test_case *  test )

static

Performs a memory check on the non volatile memory.

This function will simply test the output of the function nvm_init and returns an error in case of failure.

Parameters

test	Current test case.
