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
arm-elf-gdb
(gdb) target remote localhost:3333
NOTE: The name of your GDB program may differ. For example, with the
CodeSourcery toolchain, the ARM GDB would be called arm-none-eabi-gdb.
After starting GDB, you can load the NuttX ELF file:
(gdb) symbol-file nuttx
(gdb) load nuttx
(gdb) symbol-file nuttx
(gdb) load nuttx
Loading the symbol-file is only useful if you have built NuttX to
inclulde debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the
.config file).
NOTES:
1. Loading the symbol-file is only useful if you have built NuttX to
inclulde debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the
.config file).
2. I usually have to reset, halt, and 'load nuttx' a second time. For
some reason, the first time apparently does not fully program the
FLASH.
3. The MCU must be halted prior to loading code using 'mon reset'
as described below.
OpenOCD will support several special 'monitor' commands. These
GDB commands will send comments to the OpenOCD monitor. Here

The MCU must be halted prior to loading code. Reset will restart
the processor after loading code. The 'monitor' command can be
abbreviated as just 'mon'.

Support for the board's SPI-based MicroSD card is included
(but not passing tests as of this writing).
NOTE: If you start the program with no SD card inserted, there will be
a substantial delay. This is because there is no hardware support to sense
whether or not an SD card is inserted. As a result, the driver has to
go through many retries and timeouts before it finally decides that there
is not SD card in the slot.

And example using the NuttX graphics system (NX). This example
uses the Nokia 6100 LCD driver.
