[cdt-debug-dev] Embedded CDT cocktail
|
http://www.zylin.com/embeddedcdt.zip
Ref. my earlier posts, I've hacked up a CDT that lets me debug my
embedded target:
- GDB decides whether or not it supports the executable.
- The debug session is launched in "idle" mode. This lets the user enter
the GDB commands of his choice to start the debug session, e.g. "run",
"target remote xxx", "attach", etc.
I've tested it briefly against my arm-elf BDI 2000 JTAG debugger. Seems
to work fine. Use at your own risk! :-)
Instructions:
1. Download Eclipse SDK M9
2. Unzip embeddedcdt.zip into the Eclipse directory
Some plans:
- Let user launch CDT/GDB without executable; lets the user use the GDB
"load" command.
- Remove combo button for multiple GDB debugger types
- Write a short webpage with some tips&tricks
- Retire project once the dust settles on these GDB&CDT issues, since I
believe the eventually CDT&GDB will handle all of this out of the box.
All I did was to delete code from CDT. Patch attached.
