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?
