You're right in the sense that any "normal" ecos application is HW platform
independent. On the other side there are many platforms with specific
functionality (e.g. peripheral devices - sometimes supported by ecos drivers)
which makes transferring applications using these specific functionality much
more difficult (and sometimes impossible).

The aforementioned Falcom F35-XXl-SI module is equipped with several components
(e.g. SPI and I2C interface, GPIOs, GPS core, GPRS modem) not available on a
standard PC i386 Main Board. That could be a source of trouble when migrating
from the F35-XXl-SI to a standard pc...

The software development kit for the F35-XXl-SI contains a library of core
functions (a kind of middleware) for (nearly) HW independent application
development. If you're interested in further details you can contact me off-list.

You're right. But normally you don't have to deal with the BIOS ROM chip. See:

The F35-XXL-SI has all these features. What's wrong with it?
