   It is possible to use the i.MX RT1050  FlexSPI channels A and B separately. 

You may look at section 30.7.3 (Flash Connection) of i.MX RT1050 Reference Manual (RM),

Rev. 1, 03/2018.

  I am afraid we do not have an example just for such case. Use section 30.8 (Application information)

of the RM.


Have a great day,
