base R3.14.1 "example" application booting problem, and rdbg questions

["M.C.Shao" <ShaoMingchao97@mails.tsinghua.edu.cn>]

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,
