do you mean a unix/linux type bash/csh/sh shell ? or a GUI shell ?

rtems is an embedded operating system its not like unix where you use the shell to copy files around, edit them for configureation, etc. So there is no real need for a 'shell' as such.

Of course people have created / ported shells to rtems one of them is even quite small, i think its called 'busybox' or 'blackbox' or somehting like that, i cant remeber exactly.

>What kind of filesystem does the RTEMS use??

any you want, (or can port accross), its does have a flash filesystem and a ram filesystem.

>What's the filesystem organization??

well, as i said rtems isent unix (RNU !), its does not store parts of itself in files, the device access and other stuff is based around unix (/dev etc)

>Can RTEMS support rom filesystem??

yes,.
