configs/xtrs: Removed the XTRS configuration This was an unverified port of NuttX to a TRS-80 simulator. It was removed because (1) it is, as I said, unverified as well as unsupported, and (2) the TRS-80 simulation is a sub-optimal platform. That platform includes a 16-bit ROM image and only a 48Kb RAM space.

Configuring NuttX
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
ostest
|
||||
|
||||
This configuration performs a simple, minimal OS test using
|
||||
examples/ostest. This can be configurated as follows:
|
||||
|
||||
1) From a POSIX window:
|
||||
cd tools
|
||||
./configure.sh xtrs/ostest
|
||||
2) Modify your PATH environment variable to include the path to the
|
||||
SDCC toolchain.
|
||||
3) From a CMD.exe window
|
||||
make
|
||||
|
||||
If this is a Windows native build, then configure.bat should be used
|
||||
in step 1) instead of configure.sh:
|
||||
|
||||
configure.bat xtrs\ostest
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. See the
|
||||
"Reconfiguring" section below for information about changing this
|
||||
configuration.
|
||||
|
||||
2. The default setup for this configuration uses a windows native build.
|
||||
See the section entitled "Reconfiguring for Linux, OSX, or Cygwin"
|
||||
which will give you the steps you would need to do to convert this
|
||||
configuration to build in other, Unix-like environments.
|
||||
|
||||
3. The current build requires ca. 3.2.1 SDCC.
|
||||
|
||||
nsh
|
||||
|
||||
This configuration file builds NSH (examples/nsh). This
|
||||
configuration is not functional due to issues with use of the
|
||||
simulated serial driver (see the TODO list).
|
||||
|
||||
This configuration can be selected by:
|
||||
|
||||
1) From a POSIX window:
|
||||
cd tools
|
||||
./configure.sh xtrs/nsh
|
||||
2) Modify your PATH environment variable to include the path to the
|
||||
SDCC toolchain.
|
||||
3) From a CMD.exe window
|
||||
make
|
||||
|
||||
If this is a Windows native build, then configure.bat should be used
|
||||
in step 1) instead of configure.sh:
|
||||

|
||||
|
||||
3. The current build requires ca. 3.2.1 SDCC.
|
||||
|
||||
4. This configuration depends on configs/xtrs/src/xtrs_serial.c which
|
||||
is incomplete. At compile time, the following symbols are undefined:
|
||||
|
||||
ctrl, baud, rs232_xmtisr, rs232_recvisr, ch
|
||||
|
||||
pashello
|
||||
|
||||
Configures to use examples/pashello for execution from FLASH
|
||||
See examples/README.txt for information about pashello.
|
||||
|
||||
This configuration is not usable because the resulting binary
|
||||
is too large for the z80 address space.
|
||||
|
||||
This configuration can be selected by:
|
||||
|
||||
1) From a POSIX window:
|
||||
cd tools
|

./configure.sh xtrs/pashello
|

2) Modify your PATH environment variable to include the path to the
|
||||

||||

||||

||||

||||
|
||||
3. The current build requires ca. 3.2.1 SDCC.
|
||||
|
||||
Reconfiguring NuttX
|
||||
^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
These configurations all use the kconfig-frontends, 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 and
|
||||
additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the reconfiguration
|
||||
process.
|
||||
|
||||
Reconfiguring for Linux, OSX, or Cygwin
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
All of the z80 configurations in this this directory are set up to build in a
|
||||
Windows CMD.exe shell. This configuration requires the MinGW host compiler
|
||||
and severl GNUWin32 tools (see discussion in the top-level NuttX/README.txt
|
||||
file).
|
||||
|
||||
These configurations can be converted to run under Linux (or Cygwin or OSX),
|
||||
by modifying the configuration file as follows:
|
||||
|
||||
-CONFIG_HOST_WINDOWS=y
|
||||
-CONFIG_WINDOWS_NATIVE=y
|
||||
+CONFIG_HOST_LINUX=y
|
||||
|
||||
-CONFIG_Z80_TOOLCHAIN_SDCCW=y
|
||||
+CONFIG_Z80_TOOLCHAIN_SDCCL=y
|
||||
|
||||
You may need to first manually change the CONFIG_APPS_DIR="..\apps" definition
|
||||
in the .config file because the backslash may upset some Unix-based tools.
|
||||
|
||||
This configuration will require a recent version of SDCC (ca. 3.2.1) for Linux
|
||||
or custom built for Cygwin (see below).
|
||||
|
||||
SDCC
|
||||
^^^^
|
||||
|
||||
These z80 configurations all use the SDCC toolchain (http://sdcc.sourceforge.net/).
|
||||
Source and pre-built SDCC binaries can be downloaded from the SDCC SourceForge
|
||||
site: http://sourceforge.net/projects/sdcc/files/ . Pre-built binaries are
|
||||
available for Linux, MAC OSX, and for Win32. Various SDCC options can be
|
||||
selected with:
|
||||
|
||||
CONFIG_Z80_TOOLCHAIN_SDCCL=y : SDCC for Linux, MAC OSX or Cygwin (see below)
|
||||
CONFIG_Z80_TOOLCHAIN_SDCCW=y : SDCC for Win32
|
||||
|
||||
SDCC versions 3.2.0 or higher are recommended.
|
||||
|
||||
Building the SDCC toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
You may also want to build your own SDCC toolchain. You might want to do this,
|
||||
for example, if you are running under Cygwin and want a Cygwin compatible
|
||||
SDCC toolchain.
|
||||
|
||||
The SDCC toolchain is built with the standard configure/make/make install
|
||||
sequence. However, some special actions are required to generate libraries
|
||||
compatible with this build. First start with the usual steps
|
||||
|
||||
download
|
||||
unpack
|
||||
cd sdcc
|
||||
./configure
|
||||
|
||||
Note if you do not have the gputils packet installed, newer version of the
|
||||
SDCC configure will fail. You will have to either install the gputils
|
||||
package or if you don't need PIC14 or PIC16 support:
|
||||
|
||||
./configure --disable-pic14-port --disable-pic16-port
|
||||
|
||||
But before making, we need to apply a patch to the SDCC 2.6.0 source
|
||||
so that the z80 assembler can handle long symbol names. This is not
|
||||
needed with later versions.
|
||||
|
||||
Apply sdcc-2.6.0-asz80-symlen.patch
|
||||
cd sdcc/device/lib
|
||||
|
||||
Then make the SDCC binaries
|
||||
|
||||
make
|
||||
|
||||
and install SDCC:
|
||||
|
||||
sudo make install
