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.
