Breakpoint error

Started by mayank agarwal August 21, 2005
Hi all,
I am getting the following error while i am trying
to run the program after loading it in memory.Is
there any TI document which explains why this error
is occuring again and again.I am using DM642 emulator
board with CCS version 2.1

Breakpoint Manager: Some breakpoints are not at valid
lines.
Code Composer has moved these breakpoints to the next
valid line.
Can't Set Breakpoint: Error 0x00000008/-1076 Error
during: Break Point, Cannot set/verify breakpoint at
0x807DB3F4

Regards,
Mayank

It sure seems like you are trying to set a breakpoint on a line that the
processor does not think is executable. I will get a similar error, if
trying to set a breakpoint on code that is inside comments or a #if(0) and
#endif pair.

What is DSP-WORLD, and how to subscribe to it?

Hello Mayank,
 
I cannot answer the question about 'what document explains your error?', but I may be able to help a bit.
 
The error message that you provided is actually composed of two things -
[1] an informational message -
"Breakpoint Manager: Some breakpoints are not at valid
lines.
Code Composer has moved these breakpoints to the next
valid line"
[2] and an error message -
"Can't Set Breakpoint: Error 0x00000008/-1076 Error
during: Break Point, Cannot set/verify breakpoint at
0x807DB3F4"
 
RE: [1]
This is common among compilers when you try to set a breakpoint on a line of C code that doesn't have explicit lines of 'asm' code.  If you use the 'mixed view', you can see the relationship.  This also may occur more frequently if you are setting breakpoints in optimized code.
RE: [2]
For some reason CCS is having trouble setting a sw breakpoint at add 0x807DB3F4.
1.  Is address 0x807DB3F4 in your program??
2. open a disasm window, right click and set the address to 0x807DB3F4.  Is there valid code there??
3. open a mem window at 0x807DB3F4 and verify that you can manually change the contents.  try a few different patterns with a 'refresh window' between each.  did everything work as expected??
