Experimental Physics and
Industrial Control System

Good morning Gedare,
Now I'll get in touch with you too.
Unfortunately, I haven't really gotten around to continuing with RTEMS this year.

Fortunately, Brendan Chandler has tried to bring everything together here.
Andrew has already pointed this out: 
"Progress on our RTEMS-5 port of EPICS Base can be followed at this GitHub PR.” :
https://github.com/epics-base/epics-base/pull/105

For me it looks like this at the moment:

I use RTEMS5 und EPICS7 with the MVME6100 in production.
Unfortunately I can't use libbsd because the ethernet controller of the board is not supported.
I tried to convert the driver from Till Strauman to the nexus driver, but unfortunately didn't get
it done in 2-3 days and then aborted. Also there is no PCI/VMEbus support yet in the
libbsd. I also still use the rudimentary VME, NTP support and Till's NFS (v2).

I am satisfied with this so far in our environment. But other labs would like to use the MVME6100 
(MVME5500) with NFS3, NTP (PTP2) and especially VMEbus and loadable modules(lib).

If I have noticed correctly there is funding for dyn link loader (by HZB, Bessy) 
and NFS3 (by Gemini) for RTEMS5/6 and libbsd.

I have the MVME2500 (qoriq_e500) running quite well with libbsd and Till's NFS2.
I miss the support for PCI/VMEbus, Time-client (NTP, PTP2) and RTC.

I would like to use my new playground (MTCa4, IFC1420, FPGA) also with RTEMS. The board
is also a Qoriq based system. But again, support for PCI will be critical. I couldn't try anything yet though.

I am currently developing EPICS7 with RTEMS5 and libbsd on xilinx_zynq_a9_qemu. This works so far quite ok.
(I haven't managed to boot an image on the xilinx_zynq_a9 hardware with U-Boot yet, though, unfortunately).

Viele Grüße
Heinz
