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.

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.

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.
