OpenOCD
|

=======
|
||||
|
||||
I have also used OpenOCD with the STM3210E-EVAL. In this case, I used
|
||||
the Olimex USB ARM OCD. See the script in configs/stm3210e-eval/tools/oocd.sh
|
||||
for more information. Using the script:
|
||||
|
||||
1) Start the OpenOCD GDB server
|
||||
|
||||
cd <nuttx-build-directory>
|
||||
configs/stm3210e-eval/tools/oocd.sh $PWD
|
||||
|
||||
2) Load Nuttx
|
||||
|
||||
cd <nuttx-built-directory>
|
||||
arm-none-eabi-gdb nuttx
|
||||
gdb> target remote localhost:3333
|
||||
gdb> mon reset
|
||||
gdb> mon halt
|
||||
gdb> load nuttx
|
||||
|
||||
3) Running NuttX
|
||||
|
||||
gdb> mon reset
|
||||
gdb> c
