hello,all
Questions again.
I have update to EPICS baseR3.14.1 now. And build the "example" application for RTEMS-pc386 target.
After boot the "exmaple" application on my target machine, there are some errors delivered:
--------------
...
*****starting EPICS application*****
    assert failed: ../../../../../../../rtems-ss-20021118/cpukit/posix/src/types.c:40 0
EXECUTIVE SHUTDOWN!Any key to reboot...
--------------
Here are related contents in types.c:
38:    int POSIX_NOT_IMPLEMENTED()
39:    {
40:      assert( 0 );
41:      return 0;
42:    }
 
what does this mean? Where/when is this function called?
When I configure RTEMS, I have had the configuration option "--enable-posix" turned on.
 
And another questions, for I have realized that it's very necessary to install a rdbg environment,I installed gdb-5.2,patched with rtems patches.Then enabled rdbg in the "exmaple", after I issued command:
i386-rtems-gdb -b 38400 example
...
(gdb)target remote /dev/ttyS0
Remote debugging using /dev/ttyS0
 
This command will not return, if I type Ctrl+C after quite a while, it tells me that:
"Couldn't establish connection to remote target" 
Meanwhile, on the target machine, REMOTE DBG initialized successfully, and are waiting connection all the time.
Have I forgot anything when I use this rdbg?
 
best regards,
