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.

<b>NOTE:</b>

|
This port was removed from the NuttX source tree on 2017-11-24.
|
||||||
|
It was removed because (1) it is unfinished, unverified, and unsupported, and (2) the TRS-80 simulation is a sub-optimal platform.i
|
||||||
|
That platform includes a 16-bit ROM image and only a 48Kb RAM space for NuttX.

The removed board support is still available in the <code>Obsoleted</code> repository if anyone would ever like to resurrect it.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|

|
|
||||||
This port uses a vintage computer based on the Z80, the TRS80.
|
|
||||||
There's a main page describing the different models of TRS80.
|
|
||||||
See: http://www.trs-80.com
|
|
||||||
|

linux platform (http://www.tim-mann.org/xtrs.html).
|
|

|
|
||||||
Other emulators are available for other platforms.
|
|

See http://www.trs-80.com, click on the link Emulators.
|

||||||
|
|
||||||
TRSDOS, LDOS and other softwares are available at:
|
|
||||||
http://discover-net.net/~dmkeil/trs80/software/trs-dos.htm
|
|
||||||
|
|
||||||
Or you can get TRSDOS 1.3 and 6.1 from this site; it's included with the emulator.
|
|
||||||
http://discover-net.net/~dmkeil/trs80/model4.htm
|
|
||||||
|
|
||||||
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
|
|
||||||
testing has been performed using version 2.7.0 of the SDCC toolchain.

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
|

4. This configuration depends on configs/xtrs/src/xtrs_serial.c which

||||||
is incomplete. At compile time, the following symbols are undefined:

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

|
|
||||||
|
|
||||||
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
|
|
||||||

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
