I am using the restricted version of uVision3 along with ULink JTAG adapter, and I am trying to debug some C code. Every time I try to single step through my code it always goes to the disassembly window. If I close the window and go back to the source, it just opens the disassembly window again. This happens whether I am using the simulator or trying to debug with the hardware. Is single-stepping through source not available on the limited version?
The evaluation should support source level debugging within the limits stated.
Are you sure that you are building with debug information enabled?
Note that some of the demos are supplied as binaries only - the source is too big for the eval limits - so you woun't be able to debug them at the source level.
If you use high optimisation levels, it can be hard for the debugger to keep step with the source...
I have debug checked in the options-->output tab. Is there anything else I need to do to build with debug information? I'm not using an example, I am using a project I created myself that blinks some LEDs on and off, so I can't imagine it is too big or anything. The program runs fine, but I am trying to learn how to use uVision, hence playing with the debugger.
Benjamin; When attempting to step thru C code and the debugger takes you to the disassembly code, it can't find the symbol table that you generated with the debugger option. The symbols are linked in the OMF executable not the hex file. Are you attempting to step thru a Lib routine? Normally, the debugger will execute any called Lib routines and immediately return to the next line of C code. At what point are you getting the assembly code? Remember the startup code will be in assembly. In the Deug Options Tab, do you have 'Run to Main' checked? This option will execute the startup code, set a tempory break point at the entry of main and remove the breakpoint on break. When you start the debugger, does the program wait a the entry to main?
Can you cut and paste a fragment on the forum? Maybe some of these experts can spot a problem. Bradford
