[ECOS] ARM Simulator

[ECOS] ARM Simulator

[bier meister]

Hello,

- What can the gdb ARM simulator do in addition to
instruction set simulation? (e.g. simulate network
devices, serial links, etc.)

- Are the simulator's features documented? 
- where can one get them?

Thanks.

There is an ARM simulator that can be built into GDB.  It is
nothing more than an instruction set simulator - no I/O.

The SID project has more complete simulators, even up to a
complete ARM/PID board.  See http://sources.redhat.com/sid/
for details.  Also review the archives of this mailing list
for extended discussions on how to use SID with eCos.

Thanks to both of you for the info.  I'll look at SID.  The "architectural
only" part of the GDB based ARM simulator would probably have been fine --
all I wanted was something I could look at when I wasn't physically seated
next to the hardware, but I didn't have tremendous luck bringing that up
based on 10 minutes of work :-)

The ARM simulator is architectural only - it does not implement
any I/O devices, thus it's not suitable for running eCos applications.

What were you after?  If you just want a simulated ARM platform,
look into SID (lots of recent discussion on this list)

If your aim is to run eCos applications without any target hardware, I have
run eCos successfully under the SID ARM PID emulator, which in some ways is
better than using the GDB simulator. See
http://sources.redhat.com/ml/ecos-discuss/2002-09/msg00027.html for a HTML
mini-howto.

Note that I don't know anything about the GDB ARM simulator, I'm afraid.

[ECOS] ARM Simulator

[Patrick Doyle]

Has anybody run an eCos configuration under the ARM simulator that is built
into GDB?  I seem to recall a specific "psim" target for the PowerPC
simulator, but don't see a similar target for the ARM platforms.

Alternatively, can anybody point me in the right direction for more
information about the ARM simulator built into GDB?
