# Initialize the TI Flash DCR register
# set up extended pin set, 3 blocks, and place
# device into normal read mode.

# Set up the SRAM chip select and option register br1 & or1
# single read, 4M address space, 0 wait states
# EVB555 uses 1M for external SRAM,
# 1M for PRU
# 1M for optional HCE board,
# 1M for optional ETK SRAM
# (see table 10-7 & 10-8 of the MPC555 User Manual)
# base address is 0x00C00000

NOTE:
These three switches can be used with the write and read commands:
-b
byte read/write
-w
16-bit half word
-l
32-bit word
Create a new short cut for the SDS SingleStep program
(bdmp58.exe) and use the
/sds73/mpc555
directory as the
Start In: directory under the short cut tab. This completes the
setup of the SDS software for the MPC555 EVB.
5.
Once the software is installed, the user is ready to attach the BDM
interface. Supplied with the SDS SingleStep on-chip debugger software
will be a parallel-to-serial interface specifically for the MPC5xx series of
microcontrollers. This interface is necessary to allow your PC to
communicate via its parallel port to the BDM port on the EVB.
Connecting
the EVB to a PC
Refer to
Figure 1
and
Figure 2
when following these steps:
1.
To the parallel port on the PC, connect a cable with a male 25-pin
D-SUB connector on the other end.
2.
To the male end, attach the Macraigor BDM interface, ensuring
that the D-SUB connector is secured firmly.
