Using OpenOCD and GDB
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
I have been using the Olimex ARM-USB-OCD JTAG debugger with the STR-P711
|
||||
(http://www.olimex.com). The OpenOCD configuration file is here:
|
||||
scripts/oocd_ft2xx.cfg. There is also a script on the scripts/ directory that
|
||||
I used to start the OpenOCD daemon on my system called oocd.sh. That
|
||||
script would probably require some modifications to work in another
|
||||
environment:
|
||||
|
||||
- possibly the value of OPENOCD_PATH
|
||||
- If you are working under Linux you will need to change any
|
||||
occurances of `cygpath -w blablabla` to just blablabla
|
||||
|
||||
The setenv.sh file includes some environment varialble settings
|
||||
that are needed by oocd.sh. If you have $PATH and other environment
|
||||
variables set up, then you should be able to start the OpenOCD daemon like:
|
||||
|
||||
oocd.sh
|
||||
|
||||
Where it is assumed that you are executing oocd.sh from the top level
|
||||
directory where NuttX is installed.
|
||||
|
||||
Once the OpenOCD daemon has been started, you can connect to it via
|
||||
GDB using the following GDB command:
|
||||
|
||||
arm-elf-gdb
|
||||
(gdb) target remote localhost:3333
|
||||
|
||||
And you can load the NuttX ELF file:
|
||||
|
||||
(gdb) load nuttx
|
||||
|
||||
(There are also some files in the scripts/ directory that I used to
|
||||
get OpenOCD working with a Wriggler clone... I never got that stuff
|
||||
working).
