Chapter 5. Installation and Testing
Initial Installation Method
A Windows or Linux utility is used to program flash using serial port #1 via on-chip programming firmware. See
board documentation for details on in situ flash programming.
Special RedBoot Commands
None.
Memory Maps
The MMU page tables and LCD display buffer, if enabled, are located at the end of DRAM.
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).
