RE: Newbie - ARM simulator ???


Hi Lee,

> 1. Is the SID is required for all ECOS simulation ?

No, but it is a very convenient way to emulate target hardware, especially
as you specify ARM. Some other simulators are supported directly by eCos
(notably Power PC) but as far as I know, the ARM Instruction Set Simulator
(ISS) in GDB isn't as such. The main advantage of using SID for me was that
it looks like a real bit of hardware and it's thus like developing and
debugging on a real platform. You don't really get that with an ISS built
into a debugger.

> 2. Has anybody tried SID on a Windows platform ?

I believe someone did get it working using Cygwin. Search both ecos-discuss
and sid mailing lists for this.

> 3. Should I really be developing ECOS applications on a Linux based PC ?

Absolutely! As far as I know, only Linux and Cygwin are supported as eCos
cross-development environments.

> 4. What is a Linux Synthetic platform and how does it differ from SID ?

A Linux synthetic platform is one where eCos plus application are compiled
to run natively as a Linux application, and the devices eCos uses translate
to devices under Linux. See the eCos documentation for more information.
