The fourth test performs parameter checking of sysNvRamSet( ). This test checks that the
proper return value is given for erroneous input parameters. If this test fails, check that
error checking is provided by sysNvRamSet( ), which should return ERROR for a
negative offset or a length parameter. Also, the value of the offset plus length parameters
must be less than NV_RAM_SIZE.
The fifth test performs parameter checking of sysNvRamGet( ). This test checks that the
proper return value is given for erroneous input parameters. If this test fails, check that
error checking is provided by sysNvRamGet( ), which should return ERROR for a
negative offset or length parameter. Also, the value of the offset plus length parameters
must be less than NV_RAM_SIZE.
The sixth test writes several bytes of data (0xff), then reads back from the same NVRAM
location. This operation checks that the same data is read back, and that the buffer is
returned with a NULL termination. If this test fails, check that writing 0xff to NVRAM
does not cause a problem and that the passed-in buffer is properly terminated with EOS.
The seventh test writes several bytes of data (0x00), then reads back from the same
NVRAM location. This operation checks that the same data is read back, and that the
buffer is returned with a NULL termination. If this test fails, check that writing 0x00 to
NVRAM does not cause a problem and that the passed-in buffer is properly terminated
with EOS.
The eighth test returns NV_RAM_SIZE bytes of NVRAM back to the values read in the
first test. If this test fails, check that NV_RAM_SIZE bytes of NVRAM can be written and
read with sysNvRamSet( ) and sysNvRamGet( ).
Barring serious hardware or software limitations (such as an identifiable VxWorks
problem), the target board must pass all tests for the BSP to be validated.
