Toolchain
|
||
^^^^^^^^^
|
||
|
||
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
|
||
be modified to point to the correct path to the SH toolchain (if
|
||
different from the default).
|
||
|
||
If you have no SH toolchain, one can be downloaded from the NuttX
|
||
SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
|
||
|
||
1. You must have already configured Nuttx in <some-dir>nuttx.
|
||
|
||
cd tools
|
||
./configure.sh olimex-strp711/<sub-dir>
|
||
|
||
2. Download the latest buildroot package into <some-dir>
|
||
|
||
3. unpack
|
||
|
||
4. cd <some-dir>/buildroot
|
||
|
||
5. cp configs/arm-defconfig .config
|
||
or
|
||
cp configs/arm7tdmi-defconfig-4.3.3 .config (Last tested with this toolchain)
|
||
|
||
6. make oldconfig
|
||
|
||
7. make
|
||
|
||
8. Edit setenv.h so that the PATH variable includes the path to the
|
||
newly built binaries.

||
OpenOCD
|
||
^^^^^^^
|
||
|
||
For a debug environment, I am using OpenOCD with a Wiggler-clone JTAG interface. The
|
||
following steps worked for me with a 20081028 OpenOCD snapshot.
|
||
|
||
GENERAL STEPS:
|
||
|
||
1. Check out OpenOCD
|
||
|
||
svn checkout svn://svn.berlios.de/openocd/trunk openocd
|
||
|
||
2. Build OpenOCD
|
||
|
||
Read the INSTALL file from the files you just downloaded. You probably just need
|
||
to run:
|
||
|
||
./bootstrap
|
||
|
||
Then configure OpenOCD using the configure script created by ./bootstrap.
|
||
|
||
./configure --enable-parport
|
||
|
||
Build OpenOCD with:
|
||
|
||
make
|
||
|
||
Install OpenOCD. Since we used the default configuration the code will be
|
||
installed at /usr/local/bin/openocd. Other files will be installed at
|
||
/usr/local/lib/openocd (configuration files, scripts, etc.) and /usr/local/share/info
|
||
(online documentation accessable via 'info openocd'). You need root priviledges
|
||
to do the following:
|
||
|
||
make install.
|
||
|
||
3. Setup
|
||
|
||
OpenOCD reads its configuration from the file openocd.cfg in the current directory
|
||
when started. You have two different options:
|
||
|
||
* Create a symbolic link named openocd.cfg to one of the configuration files in
|
||
/usr/local/lib/openocd, or
|
||
|
||
* Use a custom configuration file specified with the ‘-f <conf.file>’ command line
|
||
switch opeion when starting OpenOCD.
|
||
|
||
For the STR-P711, I have included bash scripts in the scripts sub-directory.
|
||
|
||
4. Running OpenOCD
|
||
|
||
Make sure the ARM7TDMI board is powered and the JTAG cable is connected
|
||
|
||
Run 'src/openocd -d' (might be required to be root) and check for any errors
|
||
reported. The '-d' option enables debugging info.
|
||
|
||
5. Telnet interface
|
||
|
||
telnet into port 4444 to get a command interface: 'telnet localhost 4444'
|
||
|
||
6. GDB
|
||
|
||
start arm-elf-gdb
|
||
type 'file <executable.elf>' to load the executable
|
||
type 'set debug remote 1' to enable tracing of gdb protocol (if required)
|
||
type 'target remote localhost:3333' to connect to the target
|
||
The same commands from the telnet interface can now be accessed through the
|
||
'monitor' command, e.g. 'monitor help'
|
||
|
||
Configurations:
|
||
---------------
|
||
|
||
nsh:
|
||
Configures the NuttShell (nsh) located at examples/nsh. The
|
||
Configuration enables both the serial and telnetd NSH interfaces.
|
||
|
||
ostest:
|
||
This configuration directory, performs a simple OS test using
|
||
examples/ostest.
|
||
