Self-designed board

I have a self-designed DLP board using dlpc200 chipset.

I programed DLPC200 firmware into serial flash eeprom( M25P64).

After power-up, I have found 2 errors as belows

1. How can I debug it in Built-in-self-test error ?

   I saw the document about GetBISTfail API, but I couldn't know which tests performs on this API

2. As TI's documentions, GetInitFromParallelFlashFail API returns 3 state (0,1,2), but my board returns number 4.

   what does it mean?

Please give me some advice.

Regards.
