The OLED display has a built-in controller IC with synchronous serial and
|
2010-05-11 05:55:28 +02:00
|

Using OpenOCD and GDB with an FT2232 JTAG emulator
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
Building OpenOCD under Cygwin:
|
|
|
|
|
|
2019-08-05 15:13:48 +02:00
|
|
|
|
Refer to boards/olimex-lpc1766stk/README.txt
|
2013-01-21 17:56:29 +01:00
|
|
|
|
|
|
|
|
|
Installing OpenOCD in Linux:
|
|
|
|
|
|
|
|
|
|
sudo apt-get install openocd
|
|
|
|
|
|
|
|
|
|
Helper Scripts.
|
|
|
|
|
|
|
|
|
|
I have been using the on-board FT2232 JTAG/SWD/SWO interface. OpenOCD
|
|
|
|
|
requires a configuration file. I keep the one I used last here:
|
2014-04-14 00:22:22 +02:00
|
|
|
|
|
2019-08-16 15:40:59 +02:00
|
|
|
|
boards/arm/tiva/lm3s6965-ek/tools/lm3s6965-ek.cfg
|
2013-01-21 17:56:29 +01:00
|
|
|
|
|
|
|
|
|
However, the "correct" configuration script to use with OpenOCD may
|
|
|
|
|
change as the features of OpenOCD evolve. So you should at least
|
|
|
|
|
compare that lm3s6965-ek.cfg file with configuration files in
|
|
|
|
|
/usr/share/openocd/scripts. As of this writing, the configuration
|
|
|
|
|
files of interest were:
|
|
|
|
|
|
|
|
|
|
/usr/share/openocd/scripts/interface/luminary.cfg
|
|
|
|
|
/usr/share/openocd/scripts/board/ek-lm3s6965.cfg
|
|
|
|
|
/usr/share/openocd/scripts/target/stellaris.cfg
|
|
|
|
|
|
|
|
|
|
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:
|
2014-04-14 00:22:22 +02:00
|
|
|
|
|
2013-01-21 17:56:29 +01:00
|
|
|
|
- Possibly the value of OPENOCD_PATH and TARGET_PATH
|
|
|
|
|
- It assumes that the correct script to use is the one at
|
2019-08-16 15:40:59 +02:00
|
|
|
|
boards/arm/tiva/lm3s6965-ek/tools/lm3s6965-ek.cfg
|
2013-01-21 17:56:29 +01:00
|
|
|
|
|
|
|
|
|
Starting OpenOCD
|
|
|
|
|
|
|
|
|
|
Then you should be able to start the OpenOCD daemon like:
|
|
|
|
|
|
2019-08-16 15:40:59 +02:00
|
|
|
|
boards/arm/tiva/lm3s6965-ek/tools/oocd.sh $PWD
|
2013-01-21 17:56:29 +01:00
|
|
|
|
|
|
|
|
|
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) monitor reset
|
|
|
|
|
(gdb) monitor halt
|
|
|
|
|
(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).
|
|
|
|
|
2. The MCU must be halted prior to loading code using 'mon reset'
|
|
|
|
|
as described below.
|
2014-04-14 00:22:22 +02:00
|
|
|
|
|
2013-01-21 17:56:29 +01:00
|
|
|
|
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:
|
2014-04-14 00:22:22 +02:00
|
|
|
|
|
2013-01-21 17:56:29 +01:00
|
|
|
|
(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'.

An FT2232 device from Future Technology Devices International Ltd manages
|
|
|
|
|
USB-to-serial conversion. The FT2232 is factory configured by Luminary
|
|
|
|
|
Micro to implement a JTAG/SWD port (synchronous serial) on channel A and
|
|
|
|
|
a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous
|
|
|
|
|
communications links between the host computer and the target device using
|
|
|
|
|
a single USB cable. Separate Windows drivers for each function are provided
|
|
|
|
|
on the Documentation and Software CD.

The Virtual COM Port (VCP) allows Windows applications (such as HyperTerminal)
|
|
|
|
|
to communicate with UART0 on the LM3S6965 over USB. Once the FT2232 VCP
|
|
|
|
|
driver is installed, Windows assigns a COM port number to the VCP channel.

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
|
2015-06-28 16:08:57 +02:00
|
|
|
|
see additional README.txt files in the NuttX tools repository.
|
2013-05-22 15:45:03 +02:00
|
|
|
|
|
|
|
|
|
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_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot (arm-nuttx-elf-gcc)
|
|

CONFIG_ARMV7M_OABI_TOOLCHAIN=y : The older OABI version

CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary

|
3. As it is configured now, you MUST have a network connected.
|
|
|
|
|
Otherwise, the NSH prompt will not come up because the Ethernet
|
|
|
|
|
driver is waiting for the network to come up. That is probably
|
|
|
|
|
a bug in the Ethernet driver behavior!
