The following diagram shows the boot flow chart when booting from FlexSPI NOR:
but there are two things that are not clear:
1. How is the Image == XIP performed and controlled? Is it an entry like the boot start location in the "boot data"?
2. The flow diagram shows that the boot loader will copy the image (from FlexSPI NOR) to OCRAM when the test is false. Why does it copy to OCRAM? Is it because it is the largest SRAM block (128k)? Why not to ITCRAM (instruction tightly coupled)?
