Microcontrollers Debugger Manual
The
codeSize
value is an
expression.
It is usually a constant number to specify (for
security) the code size of a function where a breakpoint is set. If the size specified does not
match the size of the function currently loaded in the
.ABS
file, the breakpoint is set but it
is disabled.
The
sourceSize
value is an
expression.
It is usually a constant number to specify (for
security) the source (text) size of a function where a breakpoint is set. If the size specified
does not match the size of the function in the source file, the breakpoint is set but it is
disabled.
• If
Save & Restore on load
is checked and the user quits the debugger or loads
another .
ABS
file, all breakpoints are saved.
• If
Save & Restore on load
is clear (default), only this flag (
SAVEBP
off
) is saved.
Breakpoint File (.BPT) Example
Case 1:
If
FIBO.ABS
is loaded, and
Save & Restore on load
was checked in a previous
session of the same
.ABS
file, and breakpoints have been defined, the
FIBO.BPT
looks
as shown in
Listing 4.2
.
Listing 4.2 Breakpoint File with Save & Restore on load Checked
savebp on
BS &fibo.c:Fi19 P E; cond = "fibo > 10" E; cdSz = 47 srSz = 0
BS &fibo.c:Fi31 P E; cdSz = 47 srSz = 0
BS &fibo.c:main+12 P E; cdSz = 42 srSz = 0
BS &fibo.c:main+21 P E; cond = "fiboCount==5" E; cmd = "Assembly < spc
0x800" E; cdSz = 42 srSz = 0
Case 2:
If
FIBO.ABS
is loaded, and
Save & Restore on load was unchecked
in a
previous session of the same
.ABS
file and breakpoints have been defined, the
FIBO.BPT
looks as shown below:
savebp on
Only the flag has been saved and breakpoints have been removed.
NOTE
If only one or few functions differ after a recompile, not all breakpoints
are
lost. Breakpoints are disabled only if the size of a function changes. The size of
a function is evaluated in bytes (when it is compiled) and in characters (number
of characters contained in the function source text). When an
.ABS
file is
loaded and the matching
.BPT
file exists, for each
BS
command, the debugger
checks if the code size (in bytes) and the source size (in characters) are
different in the matching function (given by the symbol table). If there is a
difference, the debugger sets and disables the breakpoint. If there is no
difference, the debugger sets and enables the breakpoint.
