z80sim README
|
|
^^^^^^^^^^^^^
|
|
|
|
This port uses a primitive, emulated Z80 and the SDCC toolchain.
|
|
The instruction set emulator can be found in the NuttX SVN at
|
|
http://svn.code.sf.net/p/nuttx/code/trunk/misc/sims/z80sim
|
|
|
|
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 z80sim/ostest
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the mconf tool. See nuttx/README.txt and
|
|
misc/tools/
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. The default setup for this configuration uses a windows native build.
|
|
As of this writing, the native Windows build still does not work.
|
|
|
|
This configuration was last verified sucessfully prior to the
|
|
the configure to Kconfig/mconf tool using SDCC 2.6.0 built to run
|
|
natively under Cygwin.
|
|
|
|
3. This configuration 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 make also have to change the value of CONFIG_APPS_DIR. You cannot
|
|
use the default setenv.bat. Use configs/z80sim/script/setenv.sh instead.
|
|
|
|
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 z80sim/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 z80sim/pashello
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
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
|
|
|
|
Then make the SDCC binaries
|
|
|
|
cd sdcc
|
|
make
|
|
|
|
and install SDCC:
|
|
|
|
sudo make install
|
|
|
