Hello,

I have a project based on the bootfast example, where a custom scatter file is used to locate everything to SRAM.  I have added moving the interrupt vectors to SRAM and changed the VTOR register.

The image boots fine via SPIFI, but now that the program is running in SRAM I would like to re-purpose the SPIFI for another use. 

I cannot determine how to shut down the automatic memory mapping of SPIFI from the boot stage.  Any interruption of the SPIFI signals or clocks creates a hard-fault exception.

Any help you can provide is appreciated.
