FlexSPI Boot - which FlexSPI port?

Hi All,

 According to the reference manual for iMXRT1021, table 8-1 (ROM Bootloader Peripheral PinMux), the Bootloader can boot from FlexSPI_A in two places, and FlexSPI_B.

 

But I cannot see how it decides which one is the correct port?

 

Does it try all of them until it finds a good one?

 

I see nothing in the fuses or GPIO pins to control this feature?


Thanks,


Chris.
