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.

1.3.7 Power Oak K/I/S Hardware Options

Several hardware options surround the Power Oak supply to allow the user access to many of the

features. The options are sorted by leading character to indicate functionality. ‘K’ designated

options refer to VKAM and MPC564 back-up supply options. ‘I’ designated options refer to

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):
