Compiler/link issues??

I have been working on a program which had been working well, up to the point where I started adding the next functionality which is USB communications.  The function Int enc_ent_num was woking properly.  I have not looked at this function for some time until I needed it for the use of the USB section.  Now as I start using it again, it locks up the system.

Attached files are the map of the link and a screen shot from the emulation.

After running emulation - the disassembly of the code show multiplications in setting variables to 0 and after passing these steps you can see that the values set to the variables are not 0.  Any ideas of what might going on?

    Dan,

    Which DSP are you using? You do not mention this in your text, but the heading of your CCSv3 screen shot says C6720. That may be generic, but if you are using the C6720 then the address range of your enc_ent_num function is outside the valid range of internal RAM, since it only has 64KB from 0x10000000-0x1000FFFF.

    I am impressed at your use of the DIsassembly window to get more information. This is helpful for the point above, and also because the instruction code looks suspiciously corrupted and the instruction mnemonics do not look like compiled C code. It would be very unusual for the compiler to use MPY to put a 0 in a register. This is not valid program memory content being displayed at these addresses.

    If this is a valid memory range for your processor, take a look at this function as soon as you load it to see what values are there, before running to main() if possible.

    The processor used is the 6726 with 256K RAM, so I should be within the memory limits.

    I think I have found the issue.  I looked for the disassembly in emulator at load and found proper code.  As I forwarded through the program slowly, I found that the memory values had been overwritten when I collecting a chunck of data to memory.  I was able to page up in the memory view and found the variable which was causing this problem.  Turns out I did not allocate enough memory for this new variable.
