Be warned .. the IMFS is not as block oriented as it needs to
be to store all data in Flash.  I posted on this a while back.

Thanks for your answer but I think to work in a fmfs in order to build a
complete block oriented filesystem because I need a definitive tool to store
in standard way the information. IMFS is only the starting point to build
the new filesystem. Only the skeleton, not the meat.

I have the basis but the rtems structure tree is sometimes complicated to
build
the new ideas.

I think first in a extfs flopy disk system (only the information). Working
with this
to translate the concept in a user program and after touch the imfs until to
convert into fmfs.
When I work in total liberty in the user environment I can obtain these
results (a filesystem)
but I need adopt the rtems drivers philosophy because with the multitask
environment this is necesary.
