Insight on an EDB7312 board download problem

[Charles-Henri Balet]

Hello,

I work with an EDB7312 board and insight 5.3, I can connect the target with
"ARM angel serial", all
work fine, I can scan the memory, the registers, all work, but when I want
to download an exe file,
hello.exe or other, the insigth crash and all the system is out. Any has an
idea of this problem ?

many thanks for your help

Problem with Insight GUI mode

[Peter Reilley]

I have a problem with Insight 5.2.1 cross compiled for the ARM
processor.   Insight is running on X86 Linux.   I am using Insight
to connect to a remote target using Redhat's RDA.

When it starts up only the RUN button is enabled, all the others
are grayed out.   When using Insight/GDB in this manner you
cannot use the RUN command.    If I open a command window
and issue a STEP command, then everything is fine, the other
buttons are enabled.

I cannot fix this by putting commands in my .gdbinit file.    The
commands in the .gdbinit file execute properly but they do not
cause the grayed out buttons to be enabled.   Only issuing 
commands in the command window causes the condition to be 
cleared.

This behavior probably make sense for native debugging but
does not work for cross debugging.   Is there any flag to Insight
that changes this behavior?   Any other fix?

Thanks,
Pete.

[Zowie.. 5.2.1 is old, old, old. Any chance I could convince you to go
to 5.3 or CVS head?]

I'm afraid I don't understand the sequence of events. When Insight is
initially run, only the Run button will be enabled. This is correct.
When you subsequently attach to a target, the other buttons should
become enabled.

Are you saying that after attaching/downloading/etc, only the run button
remains enabled? That's a problem :-). There are a couple of things that
we might be able to do to work around the problem.

Can you open a console window and enter the commands:

(gdb) tk gdb_target_has_execution
(gdb) tk set ::gdb_running

Send the results when you are attached to the target (and the buttons
are disabled).

Try doing "tk gdbtk_update". Does that enable the buttons?

I could see that gdb would mess up the whole "set remote ..." thing. If
there's a warning in the code, then the GUI is going to display it. 
There may be a way to fix this. In remote.c, I see that when you set
this option, it calls the function query. Somehow GDB is supressing this
when starting up. If we find out how, Insight could be made to ignore
this, too.

Otherwise, as for fixing your other problems, I haven't heard anything
about whether "tk gdbtk_update" fixes the button problem. If it does,
you can add something like "tk after idle gdbtk_update" to your
.gdbinit. It'll error on non-Insight runs, though...

Can gdb do it? Running insight 5.3, use the "-nw" option to suppress the
GUI and run command line gdb. If it also crashes, ask on the gdb list
(gdb at sources dot redhat dot com).

If it does not crash and you can debug your program, can you send (to
this list) a stack bactrace? Just run Insight under gdb.

Hey,

I found the following email on the insight mailing list. Don't know whether
the subject is solved by now (couldn't find further follow-ups) or even
already
fixed in insight. But I found a way to get around the problem with "grayed
buttons"
when connecting to a remote target using a gdb script...

I'm using insight 5.3 - but experienced the very same problem (using
a remote power-pc target connecting through an Abatron BDI200 debugger).

Yep => same problem here. In addition also the source window is not
updated. So after connecting to a remote target the source window does not
show the correct source location for the current program counter.

> Can you open a console window and enter the commands:
> 
> (gdb) tk gdb_target_has_execution

tk gdb_target_has_execution returned 1
tk set ::gdb_running return 0

This updates the source window and shows the correct source location. So
this problem is fixed.
However, the buttons are still grayed.
I found out if I subsequently call
tk gdbtk_idle

Then the buttons are finally enabled! So, executing
tk gdbtk_update
tk gdbtk_idle
at the end of every gdb script file fixes the problem - well - works around
them... ;)

Kind regards,

Thorsten
