MPC564EVB User’s Manual
Support Logic
having to overwrite the ROM Monitor. The user’s code will boot from internal flash
(0x0000_0000) needs to contain the start of the Exception Vector Table).
When the switch is ON (IP is set), the behavior of the system is normal, dBUG boots and then runs
from 0x0090_0000.
Procedure:
1. Compile and link as though the code was to be placed at the base of the internal flash, but
setup so that it will download to the SRAM starting at address 0xFFF0_8000. The user
should refer to their compiler documentation for this, since it will depend upon the compiler
used.
2. Set IP bit (Switch 5 ON).
3. Download to SRAM (If using serial or ethernet, start the ROM Monitor first. If using BDM
via a wiggler cable, download first, then start ROM Monitor by pointing the program
counter (PC) to 0x0090_0100 and run.)
4. In the ROM Monitor, execute the 'upuser' command.
5. Turn off IP bit (Switch 5 OFF). User code should now be running from reset/POR.

Interrupt operation options. ‘S’ designated options refer to MPC564 Reset or I/O signal connection
options. Following is the summary table (also refer to MPC564EVB schematic):
