[ECOS] GDB doesn't run at i386 hello application

[ECOS] GDB doesn't run at i386 hello application

[Thilo Hutt]

Hello,

From the templates I had build a Redboot floppy binary image for an i386 with intel 82544 interface and it run at the PC. Now I had rebuilt eCos with package "default" and linked the libraries with the hello example. When I download the application with the load command via yModem over serial or TCP/IP the application run and put out the "hello, ecos World!". But if I want to debug the application with gdb, set to target remote <ipadress>:9000 the debugger stops inside the library module atexit.cxx and runs no more. I had to restart the target pc. Here are the GDB steps:

(gdb) file hello
Reading symbols from /cygdrive/h/Triton/Test/hello...done.
(gdb) target remote 192.168.50.131:9000
Remote debugging using 192.168.50.131:9000
0x000108d5 in ?? ()
    at /ecos-c/cygwin/opt/ecos/ecos-2.0/packages/language/c/libc/startup/v2_0/src/atexit.cxx:85
85      cyg_libc_invoke_atexit_handlers( void )
Current language:  auto; currently c++

.......


And I'm no more able to run the program or step any line.

Did I use the wrong gdb commands?
Or must I use a different package than "default" to use the gdb inside the application?

Regards,
Thilo

Silly question,
Did you load the file to the target? Or did GDB hang immediately  
after the target command. You don't show what happened next.
