MIMXRT1060 flash read and write

Hello everyone, I am using MIMXRT1060-EVK dev-kit to write and read from the flash.


In the fact sheet of MIMXRT1060, it says the dev-kit has 

256Mb SDRAM
512Mb Hyper Flash
64Mb QSPI Flash

The source: https://www.nxp.com/docs/en/fact-sheet/IMXRTEVKFS.pdf


However, the address that I am assuming for the qspi is 0x6000 0000. 

 


But, in the reference manual, it says FlexSPI/FlexSPI ciphertext is at 0x6000 0000 and utilizes 256Mb.

My questions:

1)  How do we know at address 0x6000 0000 is for QSPI not another type of flash ? 

2) And how big is QSPI flash 64Mb? or 256Mb?

3) Is there any example project that is writing and reading from the flash using just flexspi API without a bootloader. 

4) What is the difference and when to use for ( flexspi with the bootloader VS Flexspi without bootloader ) ? 

Thank you very much for your time and consideration.
I really appreciate your help.
