Hi Tim,
I'm sorry, I wasn't clear. I want this to be an RTEMS application, not a Linux application. We have been doing this with linux for several years, but only recently it seemed that RTEMS was more complete and robust than it used to be, so I'd like to explore
that.
Pete.

Hi Pete,
I think Kiman Ha did that to make copies of softGlueZynq
run at NSLS (because someone wanted to use the scaler in softGlueZynq). As far as I know, Kiman's solution boots from the MicroSD card and autostarts an EPICS IOC. You can run the EPICS IOC with or without softGlueZynq.

I need to build an EPICS IOC which can run without access to NFS mounts or TFTP mounts. The embedded system is a ZynQ-based system with ample persistent storage on a micro-SD card. It seems to me that libbsd provides a full range of file I/O facilities, and
so a more Linux-like configuration should be possible. But I have no idea how to accomplish this! I suspect that I need to change ~/epics/base-7.0/modules/libcom/RTEMS/posix/rtems_init.c, since that seems to be where the NFS/TFTP stuff gets set up. Has anyone
tried to do this?
Pete.
