Instruction stepping went away

I used to be able to use instruction stepping, but now it's grayed out. I can single step code just fine, I can view the disassembly, i just can't get back to where I can step through the disassembly.

Using LPCXpresso v4.2.3 on Ubuntu Precise.

Problem shows up with an LPC1113 board I designed and is now in production, using Red Probe+.

Also shows up on LPC-Link card for LPC1769 using the built-in probe.

[B]Displaying assembly instructions when debugging[/B]

It is sometimes useful to be able to view the actual assembly instructions of your application when you are debugging. This can often assist in understanding the behavior you see as the application executes.
One way to do this is to change into "Instruction Stepping Mode". To do this click on the "[B]i->[/B]" icon in the Debug view.

This changes debug behavior such that you will now step by processor instructions, rather than source lines. It will also cause the Disassembly view to be added to your current perspective, which will display instructions around the current program counter.
If you click the "[B]i->[/B]" icon again to return to source stepping mode, the Disassembly view will continue to be displayed.
Alternatively the menu [B]Window->Show view->Other->Debug->Disassembly[/B] will cause the Disassembly view to be displayed (without changing the current stepping mode).

Hmmmm, that picture was reduced to useless. I'll try a Zip of the picture.

I found the problem, sort of...

The proper thread was selected but it wasn't working. If I pick another thread and come back, THEN it works.

The screen shot is before I pick anther and then come back.

I presume that you mean the "i->" icon is greyed out within the Debug view's tool bar?

Normally the only time this will happen is if you have selected an entry in the main part of the Debug view that is not part of the call stack. In the Debug view you will see something like the following...

<AppName> Debug [C/C++ MCU Application]
 - MCU GDB Debugger....
    - Thread [1] ....
       - [I]<current func name>[/I]
       - [I]<caller func1>[/I]
       - [I]<caller func2>[/I]
           :
       - main...
    - arm-none-eabi-gdb...
    - <Location of AXF>

Make sure you select the "Thread" line or one of the functions under it. The "i->" icon should then be active.

If this doesn't solve the problem for you, then please provide more details of what you are actually seeing (and potentially a screenshot).
