Blackfin BF51x, SPI baud for SPI Master Boot

We can see following description on BF51x Hardware Reference, rev.1.2, page 1283/1524.


In SPI master boot mode, the OTP_SPI_BAUD register in the preboot half page PBS00L controls the value written to the SPI0_BAUD registers.


We have tried to change SPI0_BAUD( not OTP_SPI_BAUD ) directly in initcode (not in preboot) and observed it seems to be working good.

Could you please make sure whether we do NOT need to use OTP_SPI_BAUD, if not use OTP ?


Best Regards,
