    I test TrueRNG with 256MB/512MB/1G sampls

    256MB: 1 FAILED / 7 WEAK
    512MB: 1 FAILED / 3 WEAK
    1G: 0 FAILED / 3 WEAK

    But other device generate 256MB sample is passed with dieharder.

    Your data sample set is too small for dieharder, we typically run it with 10-14 gig of data. If oyu look at the top you see:

    ” # The file file_input_raw was rewound 48 times ” comment.

    When it rewinds, it thinks it sees a pattern. This is documented in the dieharder documentation.

    Other devices may pass if they filter out these failures prior to
    providing the data (especially if pseudorandom). But, for a true hardware
    random number generator, some failures are expected.
