static void cdc_uart_init ( void  )

static

Initialize USART for unit tests.

Initializes the USART used by the unit test. The USART connected to embedded debugger is used for outputting the results.

int main

(

void

)

Run NVM unit tests.

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

static void run_nvm_erase_test ( const struct test_case *  test )

static

Test NVM erasing.

This test erases test row and verifies it

Parameters

test	Current test case.

static void run_nvm_init_test ( const struct test_case *  test )

static

Test NVM initialization.

This function will write the default configuration to NVM and returns an error in case of failure.

Parameters

test	Current test case.

static void run_nvm_parameter_test ( const struct test_case *  test )

static

Test get flash parameter function.

This test gets the nvm parameters from the function and checks the NVM page count and NVM page size

Parameters

test	Current test case.

static void run_nvm_read_and_write_test ( const struct test_case *  test )

static

Test NVM writing.

This test writes erased test page with a pattern, reads it back and checks the integrity

Parameters

test	Current test case.

static void run_nvm_update_test ( const struct test_case *  test )

static

Test NVM update.

This test modifies first half of the test page with different pattern, reads it back and checks whether the values are updated

Parameters

test	Current test case.
