Hello Enrique,

I will try to answer your questions up to my knowlegde of emc and linux.
> 
> 1.- why there are no files under emc/plat/rtlinux_xx/bin ?
Well there are two popular realtime linux flavours out there rtlinux and RTAI.
Both work by patching the linux kernel so that a realtime scheduler takes care
of of different tasks. The linux kernel is just one of these tasks. Other tasks
are in our emc example reading and writing data from and to your
machine/amplifiers/feedback etc.
These tasks have to be loaded into the kernel. This is done by loading
modules-lsmod gives you the currently loaded ones. But these modules are not
binaries==executable programs. So emc/plat/rtlinux_xx/bin
is empty, and emc/plat/linux_xx/bin is full of programs.

Yes.

> 3.- Why there are no emcserver nor emcstrip values in emc.ini?
emcserver is for running the gui from a different machine. emcstrip is for
displaying and making nice graphs. If you want to build and use this you need
some values in emc.ini, but my put this in as a default while most people do
not use it ?

> 4.- does it make a difference to specify realtime vs nonrealtime in the
> PLAT values for EMCIO and TASK sections?
Never thought about this myself. Is there a IO Controller for realtime ?

> 5.- Is there a way to get around this shared memory segment issue?
> 
No. As far as I understand, the different parts communicate by shared memory
segments. You need them.

If you need some help, contact me off-list.
