Chapter 4:Connecting the Emulator to a Target System
Selecting a clock module
Another possible solution to data access problems is to use faster memories while
using the emulator.
Installing the emulator in a target system without
known good software
If you do not have a program in ROM on your target system that you can run to
electrically test the emulator, you will need to create a test environment. The initial
step of this is to use the emulator's memory to install a simple program that will
run from reset. To do this, proceed as follows:
78
1 Turn on emulator power.
2 Check the prompt by pressing <RETURN>.
The prompt should be "p>". A "->" prompt indicates a software compatibility
problem. Correct problems indicated in error messages or check the version
"ver" for more information.
3 Configure the emulator by entering the following commands:
cf mon=bg
cf berr=en
cf xdma=en
cf ti=en
cf db=<32,16>, as appropriate for your target system
cf glbcs=<32,16,8>, as appropriate for your target system
4 Map memory with the following command:
map 0..0fff eram dstgt
This maps a block of emulation memory starting at address 0 so that the reset
vectors will be accessed from this block. The block is configured to be
interlocked to the target system strobes because all systems must have some
memory that responds at address 0 to operate.
