xtrs README
^^^^^^^^^^^^^
TRS80 Model 3. This port uses a vintage computer based on the Z80.
An emulator for this computer is available to run TRS80 programs on a
linux platform (http://www.tim-mann.org/xtrs.html).
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
testing has been performed using version 2.6.0 of the SDCC toolchain.
Configuring NuttX
^^^^^^^^^^^^^^^^^
ostest
This configuration performs a simple, minimal OS test using
examples/ostest. This can be configurated as follows:
cd tools
./configure.sh xtrs/ostest
cd -
. ./setenv.sh
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:
cd tools
./configure.sh xtrs/nsh
cd -
. ./setenv.sh
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:
cd tools
./configure.sh xtrs/pashello
cd -
. ./setenv.sh
Building the 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
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
Apply sdcc-2.6.0-asz80-symlen.patch
cd sdcc/device/lib
Then make the SDCC binaries
cd sdcc
make
and install SDCC:
sudo make install
