If you do this a lot, you will probably want to invest a little time
to develop a tool to automate these steps.
Flashing and Debugging
======================
NuttX firmware Flashing with STLink probe and OpenOCD::
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c 'program nuttx.bin 0x08000000; reset run; exit'
Remote target Reset with STLink probe and OpenOCD::
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c 'init; reset run; exit'
Remote target Debug with STLink probe and OpenOCD:
1. You need to have NuttX built with debug symbols, see :ref:`debugging`.
2. Launch the OpenOCD GDB server::
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c 'init; reset halt'
3. You can now attach to remote OpenOCD GDB server with your favorite debugger,
for instance gdb::
arm-none-eabi-gdb --tui nuttx -ex 'target extended-remote localhost:3333'
(gdb) monitor reset halt
(gdb) breakpoint nsh_main
(gdb) continue
