sCheck shutdown tests failing on Application

Hi,
the execution of some sCheck shutdown test on Application is failing (the test signature is showing a value great then 0 in the LSB 16 bits).

Is it possible to understand the reason why it is failing?

Here are the screenshots of the faulty tests.

Thanks in advance!

Hello Joey,
the sCheck_ExecuteShutdownTests function just returns a value related to the function execution itself, that's why I was focused to debug the "inside" functions.
In fact I posted some screenshots showing that the test Signature contained the 16 LSB of it with a value not egual to 0.

to be more clear, why I get the following signatures:

  1. 0xB6A90004 (what is it the meaning of the last 4)
  2. 0xDAD00001 (what is it the meaning of the last 1)
  3. 0xDACD0001 (what is it the meaning of the last 1)


Thanks!

hi,msoddu2

Thank you for your reply.

Refer to the sCheck user manual and the perspective of the program, these values of yours are Accumulate signatures. If all tests are executed successfully, it should be equal to ExpectedSignature.

hi,msoddu2

Thank you for contacting us.

You can try to check the Shutdown test in the sCheck_ExecuteShutdownTests function. The function includes sCheck_ExecuteSimpleTestBatch.
