Inverse Assembler Problems

This section lists problems that you might encounter while using the
inverse assembler.
When you obtain incorrect inverse assembly results, it may be unclear
whether the problem is in the analysis probe or in your target system. If
you follow the suggestions in this section to ensure that you are using
the analysis probe and inverse assembler correctly, you can proceed
with confidence in debugging your target system.
No inverse assembly or incorrect inverse
assembly
This problem is due to incorrect synchronization, modified
configuration, incorrect connections, or a hardware problem in the
target system. A locked status line can cause incorrect or incomplete
inverse assembly.
❏ Verify that the inverse assembler has been synchronized by placing an
opcode at the top of the display (not at the input cursor) and pressing the
Invasm key.
Because the inverse assembler works from the first line of the trace
display, if you jump to the middle of a trace and select Invasm, prior trace
states are not disassembled correctly. If you move to several random
places in the trace list and select Invasm each time, the trace disassembly
is only guaranteed to be correct from the top of the display forward for
each selection.
