The iMX RT1050 ROM will allow you to copy an application image from a serial NOR flash memory on the FlexSPI controller to SDRAM at boot time. If you want to run your application from SDRAM, then when debugging and developing your application you should use an initialization script for the debugger to setup the SDRAM so the application can be downloaded directly to the SDRAM for debugging.

 

When you are ready to have your application boot without the debugger, then you'll need to use the RT flashloader tools to program the application to the flash and configure it to copy to the SDRAM. The attached document contains instructions on how to program a boot image to serial NOR flash (in this case the hyperflash that is on the EVK) that will be copied to the SDRAM at boot time.
