Chapter 5: Plugging into a Target System
Configuring the Emulator for In-Circuit Operation
Here is an example where a "trace on_halt" command was used to find the cause of
a double-bus fault:
XDEF
ORG
DC.L
DC.L
ORG
MOVE.W
MOVEA.L
MOVE.W
MOVE.W
MOVE.W
JSR
MOVE.W
MOVE.W
NOP
CS_INIT NOP
...
The memory map used in this configuration includes:
000000H thru 1FFFFH emulation ram
400000H thru 43FFFFH target ram
The commands issued were:
trace on_halt <RETURN>
run from reset <RETURN>
after which the status line will show "M68302--Halted". At this point, you must
"halt" and display the trace using the commands:
stop_trace <RETURN>
display_trace <RETURN>
