The following illustration shows an XIP image:
Note:
In the following pseudo-code examples,
image_paddr represents the source location of the
image in linear ROM, and ram_paddr represents
the image's destination in RAM.
Here are the steps required in the IPL:
checksum (image_paddr, startup_size) checksum (image_paddr + startup_size, stored_size - startup_size) copy (image_paddr, ram_paddr, startup_size) jump (startup_vaddr)
