pjrc-8051 README
^^^^^^^^^^^^^^^^
z80sim README
^^^^^^^^^^^^^
This port uses a primitive, simulated Z80 and the SDCC toolchain.
This port uses a primitive, emulated Z80 and the SDCC toolchain.
The instruction set emulator can be found in the NuttX CVS at
http://nuttx.cvs.sourceforge.net/nuttx/misc/sims/z80sim
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
testing has been performed using verison 2.6.0 of the SDDC toolchain.
Configuring NuttX
^^^^^^^^^^^^^^^^^
defconfig
The default configuration file, defconfig, performs a simple,
minimal OS test using examples/ostest. This can be
configurated as follows:
cd tools
./configure.sh z80sim
cd -
. ./setenv.sh
nshconfig
This configuration file builds NSH (examples/nsh).
This alternative configurations can be selected by:
(Seleted the default configuration as show above)
cp config/z80sim/nshconfig .config
Building the SDCC toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^^^
