[ECOS] RE: gdb/insight problem

[Avi Vaknin]

Hi Jifl,
Yes. The program is definitely running and we are sure we connected in the firts 
place (using File->Target Setup) and set up as a Remote/TCP target, with 
the appropriate board's IP address/name.

Any idea?

Thanks,
Avi.

The program is definitely running? Are you sure you connected in the firts 
place (using File->Target Setup) and set up as a Remote/TCP target, with 
the board's IP address/name?

That shared library warning is something I've seen elsewhere, and it's not 
been a problem before. Have you tried command line GDB?

Hi,
Below is the output of the command line GDB when running hello application as you requested:
 

[kuku@temp]$ powerpc-eabi-gdb .../hello 

GNU gdb 5.3

Continuing.

The shell hangs after the above step. 


As you have seen, the shared library warning is still persisting.
Any idea?

Thanks,
Avi.

Shrug. Do nothing if you prefer.

I don't know, but it's a way to find out.

No.
We tried to work with Insight and not through command line GDB.
Assuming that we can run it in command line GDB, what could be problematic when using Insight?

The program is definitely running? Are you sure you connected in the firts 
place (using File->Target Setup) and set up as a Remote/TCP target, with 
the board's IP address/name?
