Hi everybody,

I work with Epics R3.13.1 for PPC (MVME2306). I installed the second Ethernet
interface board (TPMC880). Since the driver delivered with the board was
developed under Tornado 2.0, I switched also to Tornado 2.0, vxWorks 5.4
(previously I worked under Tornado 1.0.1, vxWorks 5.3). I've made all the
necessary changes in vxWorks image to add the second interface as "dc"
unit 1 (as it was recommended by the board developers).

I changed the default port number for CA by
'putenv("EPICS_CA_SERVER_PORT=6025")' shell command before the EPICS
initialization.

Just for testing I downloaded a database consisting of the only waveform
record. The EPICS initialization didn't finish properly. I had the following
messages after iocInit:

> iocInit
> ############################################################################
> ###  @(#)EPICS IOC CORE
> ###  @(#)Version R3.13.1..0 $$Date: 1999/11/09 09:47:55 $$

> Task: 0x19ed0a8 "CA online"

> task 19ed0a8 CA online suspended

Then in some while I got:

> 0x1bbd0e8 (tNetTask): arptnew failed on 83a970bd

I didn't attach still the second interface.

I rebooted the PPC using unchanged vxWorks image. But with the same
result. What could be the cause of such behaviour?

Thank you in advance for any advice or help,

V.Korobov
