Using OpenOCD and GDB with an FT2232 JTAG emulator
|
|
==================================================
|
|
|
|
Downloading OpenOCD
|
|
|
|
You can get information about OpenOCD here: http://openocd.berlios.de/web/
|
|
and you can download it from here. http://sourceforge.net/projects/openocd/files/.
|
|
To get the latest OpenOCD with more mature lpc214x, you have to download
|
|
from the GIT archive.
|
|
|
|
git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
|
|
|
|
At present, there is only the older, frozen 0.4.0 version. These, of course,
|
|
may have changed since I wrote this.
|
|
|
|
Building OpenOCD under Cygwin:
|
|
|
|
You can build OpenOCD for Windows using the Cygwin tools. Below are a
|
|
few notes that worked as of November 7, 2010. Things may have changed
|
|
by the time you read this, but perhaps the following will be helpful to
|
|
you:
|
|
|
|
1. Install Cygwin (http://www.cygwin.com/). My recommendation is to install
|
|
everything. There are many tools you will need and it is best just to
|
|
waste a little disk space and have everything you need. Everything will
|
|
require a couple of gigbytes of disk space.
|
|
|
|
2. Create a directory /home/OpenOCD.
|
|
|
|
3. Get the FT2232 driver from http://www.ftdichip.com/Drivers/D2XX.htm and
|
|
extract it into /home/OpenOCD/ftd2xx
|
|
|
|
$ pwd
|
|
/home/OpenOCD
|
|
$ ls
|
|
CDM20802 WHQL Certified.zip
|
|
$ mkdir ftd2xx
|
|
$ cd ftd2xx
|
|
$ unzip ..CDM20802\ WHQL\ Certified.zip
|
|
Archive: CDM20802 WHQL Certified.zip
|
|
...
|
|
|
|
3. Get the latest OpenOCD source
|
|
|
|
$ pwd
|
|
/home/OpenOCD
|
|
$ git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
|
|
|
|
You will then have the source code in /home/OpenOCD/openocd
|
|
|
|
4. Build OpenOCD for the FT22322 interface
|
|
|
|
$ pwd
|
|
/home/OpenOCD/openocd
|
|
$ ./bootstrap
|
|
|
|
Jim is a tiny version of the Tcl scripting language. It is needed
|
|
by more recent versions of OpenOCD. Build libjim.a using the following
|
|
instructions:
|
|
|
|
$ git submodule init
|
|
$ git submodule update
|
|
$ cd jimtcl
|
|
$ ./configure --with-jim-ext=nvp
|
|
$ make
|
|
$ make install
|
|
|
|
Configure OpenOCD:
|
|
|
|
$ ./configure --enable-maintainer-mode --disable-werror --disable-shared \
|
|
--enable-ft2232_ftd2xx --with-ftd2xx-win32-zipdir=/home/OpenOCD/ftd2xx \
|
|
LDFLAGS="-L/home/OpenOCD/openocd/jimtcl"
|
|
|
|
Then build OpenOCD and its HTML documentation:
|
|
|
|
$ make
|
|
$ make html
|
|
|
|
The result of the first make will be the "openocd.exe" will be
|
|
created in the folder /home/openocd/src. The following command
|
|
will install OpenOCD to a standard location (/usr/local/bin)
|
|
using using this command:
|
|
|
|
$ make install
|
|
|
|
Helper Scripts.
|
|
|
|
I have been using the Olimex ARM-USB-OCD JTAG debugger with the
|
|
ZP213X/4XPA. OpenOCD requires a configuration file. I keep the
|
|
one I used last here:
|
|
|
|
boards/zpa214xpa/tools/olimex.cfg
|
|
|
|
However, the "correct" configuration script to use with OpenOCD may
|
|
change as the features of OpenOCD evolve. So you should at least
|
|
compare that olimex.cfg file with configuration files in
|
|
/usr/local/share/openocd/scripts/target (or /home/OpenOCD/openocd/tcl/target).
|
|
|
|
There is also a script on the tools/ directory that I use to start
|
|
the OpenOCD daemon on my system called oocd.sh. That script will
|
|
probably require some modifications to work in another environment:
|
|
|
|
- Possibly the value of OPENOCD_PATH and TARGET_PATH
|
|
- It assumes that the correct script to use is the one at
|
|
boards/arm/lpc214x/zp214xpa/tools/olimex.cfg
|
|
|
|
Starting OpenOCD
|
|
|
|
Then you should be able to start the OpenOCD daemon like:
|
|
|
|
boards/arm/lpc214x/zp214xpa/tools/oocd.sh $PWD
|
|
|
|
If you add that path to your PATH environment variable, the command
|
|
simplifies to just:
|
|
|
|
oocd.sh $PWD
|
|
|
|
Where it is assumed that you are executing oocd.sh from the top-level
|
|
directory where NuttX is installed. $PWD will be the path to the
|
|
top-level NuttX directory.
|
|
|
|
Connecting GDB
|
|
|
|
Once the OpenOCD daemon has been started, you can connect to it via
|
|
GDB using the following GDB command:
|
|
|
|
arm-nuttx-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
|
|
|
|
NOTES:
|
|
1. Loading the symbol-file is only useful if you have built NuttX to
|
|
include debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the
|
|
.config file).
|
|
|
|
OpenOCD will support several special 'monitor' commands. These
|
|
GDB commands will send comments to the OpenOCD monitor. Here
|
|
are a couple that you will need to use:
|
|
|
|
(gdb) monitor reset
|
|
(gdb) monitor halt
|
|
|
|
NOTES:
|
|
1. The MCU must be halted using 'mon halt' prior to loading code.
|
|
2. Reset will restart the processor after loading code.
|
|
3. The 'monitor' command can be abbreviated as just 'mon'.
|
|
|
|
Configurations:
|
|
===============
|
|
|
|
Each NXP LPC214x configuration is maintained in a sub-directory and
|
|
can be selected as follow:
|
|
|
|
tools/configure.sh zp214xpa:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh:
|
|
----
|
|
|
|
Configures the NuttShell (nsh) located at examples/nsh. The
|
|
Configuration enables only the serial NSH interfaces.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. Default platform/toolchain:
|
|
|
|
CONFIG_HOST_LINUX=y : Linux (Cygwin under Windows okay too).
|
|
CONFIG_ARM_TOOLCHAIN_GNU_EABI=y : Buildroot (arm-nuttx-elf-gcc)
|
|
CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary
|
|
|
|
nxlines:
|
|
--------
|
|
|
|
This is the apps/examples/nxlines test using the UG_2864AMBAG01 board
|
|
from The0.net that plugs into the "SPI LCD" connector on the ZP3X4XPA
|
|
board.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. Default platform/toolchain:
|
|
|
|
CONFIG_HOST_LINUX=y : Linux (Cygwin under Windows okay too).
|
|
CONFIG_ARM_TOOLCHAIN_GNU_EABI=y : Buildroot (arm-nuttx-elf-gcc)
|
|
CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary
|
|
|
|
STATUS:
|
|
2012-12-30: Configuration verified.
|
|
|
|
2017-11-25: Grrr... This configuration no longer works. Some serious bit
|
|
rot has set in. Now only random garbage appears on the OLED. Certainly
|
|
a lot has changed since 2012, but I cannot see any change to either this
|
|
configuration, to the LCD driver, or to the LPC2148 support that would
|
|
affect the operation of the LCD. The nsh configuration is still functional.
|
