Memory Maps
RedBoot sets up the following memory map on the CerfCube: The first level page table is located at physical
address 0xC0004000. No second level tables are used.
NOTE: The virtual memory maps in this section use a C and B column to indicate whether or not the region is
cached (C) or buffered (B).
