Experimental Physics and Industrial Control System
hi,
I am booting the EPICS example application on i386-rtems target with a new rtl8139 driver. The driver has been tested successfully.
when "starting the application" during booting process, an error was delivered, the error message is:
--------------------
filename="../dbLexRoutines.c" line number=238
I/O error dbRead opening file db/dbSubExample.db
Starting iocInit
iocInit:All initilization complete
epics>
--------------------
As above indicate, all initilization complete, and I could type the shell command, such as dbl, dbpr, etc.
But when I use medm to connect to the records of the ioc, exception was encounterd.The following are messages that appear in the medm message window:
---------------------

-------------------------
"166.111.32.240" is the ip address of the ioc.
What's the reason?any suggestions are appreciated. Thanks in advance.
