This is the README file for ARMulator version 1.0, an ARM6 instruction
|
|
emulator.
|
|
|
|
Configuration:
|
|
The armulator has one configuration option, the default endianness
|
|
of the processor. This can be changed by building with ENDIAN=BIGEND
|
|
to produce a big-endian variant. The debugger can also select the
|
|
endianness at run-time.
|
|
|
|
Build instructions:
|
|
|
|
This program is known to compile using GCC 2.6.0 on a Sun4. Other
|
|
builds are untested. It almost certainly will not work on non-32bit
|
|
machines.
|
|
|
|
To build the program simply type make in the source directory,
|
|
followed by "make install"
|
|
|
|
Using the emulator:
|
|
|
|
The emulator runs as a separate process, and communicates with a
|
|
debugger via tcp. To start the emulator type
|
|
armul <socknum>
|
|
where socknum is any number between 1024 and 65535. If the socket is
|
|
already in use, armul will exit with an error.
|
|
|
|
This version of armul has been designed to work with gdb-4.13
|
|
with the ARM/RDP/RDI extensions added (available separately). To
|
|
connect gdb to the ARMulator, start gdb and type
|
|
target arm <hostname>:<socknum>
|
|
where hostname is the name of the machine on which the armulator
|
|
is running, and socknum is the socket number specified when armul
|
|
was started.
