Apr.13 gdb via arm-elf-insight forte

1.  Change gcc optimize level to -O0 from -O3

make dist clean followed by make all

Note:  FORTE grows from around 160k to 230k so lower levels of optimization only help for very small applications since 256k is max available.

1b. run openocd_flash.bat 

2a. run  openocd.bat

2b. In cygwin start:  arm-insight-elf 

current path: (if gdb does not remember for you)
aa@automatix /cygdrive/d/AA_local/eclipseWork/forte_lms_neu/bin/lms/src
$ arm-elf-insight forte

3. In gdb 

• run connect to target
• wait
• in Console window:
•  monitor reset
•  monitor halt - so can set breakpts

3b. Set breakpoints
No more than 2 breakpts, since chip only allow 2 breakpoints
  and only 1 breakpoint, if you want to step because 1 breakpt is used for stepping

•   select source file 
•   -    next to a line indicates where breakpoints are possible
•  click  on - to set breakpoint for a line
•  verify via view/breakpoints 
• delete extra breakpoints

Note: if drop-down for select source has disappeared, close all windows except source (main) window and  console window;  exit gdb; restart in cygwin
4. after settting the breakpoint  then...

• continue (far right of run symbol)
• wait for  boot to finish indicated by: blinking / sound of a device connecting to PC

5.  run download program in java eclipse

6.  download application from 4diac
Stops running at breakpoint
7. examine state at breakpoint
can now view/ local variables or watch
QI is really a #define
 so use the form this->mpapp0DI[0] for watch expression

NOTE: C++ will not compile if gdb is open!
