Remote debugging

Remote debugging

[Russell Shaw]

Hi,
I'm trying to set up running gdbserver on a laptop and ddd/gdb on a desktop pc.

Apart from exporting an NFS directory from the laptop, what other easy way is 
there to get the compiled binary debugee automatically transferred from the 
desktop to the laptop?

Hi Russel,
I hope this is what you're looking for.

I see two approaches:
1) File system sharing/copying utility
    Similar to what you suggested, NFS, scp, etc.

    I do remote debugging all the time with gdb and gdbserver, and I have this
    batch file (both my host and target are Windows OSes) that copies
my binaries
    over SMB share.

    If you build your sources frequently, and you're paranoid about
typing the same commands
    over and over again, how about adding a post-build command to call
this script to deploy the files?


2) Transferring files via remote protocol
     Once you're connected from gdb to gdbserver, you can use the
following command [1]:
     remote put <host file> <target file>

     However, this might be an overkill as it will require gdbserver
[2] to be attached to
     some dummy process, and will most likely require you to start new
gdb and gdbserver
     processes in order to debug the new binary.

I personally consider option #1 as a valid and normal way of
host2target remote debugging workflow.

Hi,

I put in /home/russell/myprogdir/.gdbinit:

target extended-remote main:1234

cd /home/russell/myprogdir

file myprog
remote put myprog myprog2

break main

run

define hook-run
kill
file myprog
remote put myprog myprog2
end


I was going to do on the laptop (the above test is all in the same directory on 
the same pc):

gdbserver main:1234 myprog2


When testing with gdbserver invoked on the same pc (main) in the same directory 
(/home/russell/myprogdir), "myprog" is truncated to 0 bytes by "remote put 
myprog myprog", so i had to use myprog2 for the copy. I filed a bug for that.

"remote put" should first copy myprog to /tmp/, open the remote myprog for 
writing (which truncates it), then copy from /tmp/. Another way is to note the 
source and dest are the same, and skip the copying.

In this case, for such an embedded appilcation, do you think it could be
reasonable to compile all the application stuff along with the Linux kernel?
Then probably my program would appear as a kernel thread (??) so that it can
be debugged using gdb stubs for kernel debugging.

Do you see any drawback in this approach?
Is there a "standard" or "common" approach for this kind of application?

Thanks a lot. Regards.

[luca risso]

Hi,

I'm trying to debug an application running on a PPC board with Linux 2.4.25.

I'm new about this kind of environment so please don't be surprised if my 
question seems too silly.
Using GDBServer I can run the program on the target and set breakpoints to 
stop a thread.
I seems to me that should be possible (I've still not experinced that) also 
to stop all threads of a process on the same breakpoint.

Now, is it possible someway to stop all processes running on the board?
It would be useful when debugging processes sending messages to each other.
Something similar is available using psos and VxWorks environments where all 
processes seems to be "freezed" at a time.

May it be useful to compile all my stuff  along with Linux and then use gdb 
stubs normaly adopted for kernel debugging?

Thanks for your help

No, it's not possible.  GDB can only manage one process at a time.

By the way, every time you stop a thread, GDB arranges for all threads
in that process to stop.  GDB doesn't currently support any other mode.

remote debugging

[Brijesh Shukla]

Hello,
 
Can any body explain the remote debugging application in Linux. 
currently for testing purpose as simple case, I have chosen two i686 
Pentium machines with Linux
installed on two systems. on system I am running gdb and in another 
system I am running gdb server. I did the following steps.
 
Target:
 gdbserver host:port program
 
 //Now gdbserver has been started
 
Host:
 
 // I compiled the simple hello word program as    gcc -g program.c -o 
program
 // copied the program into target system
 
 gdb program
 gdb> target remote host:port
 gdb>
 
 // connection established
 gdb> load
 
 // it is showing loading the sections, I m not sure the addresses from 
local machine or from target machine ( how can I verify ? in our 
case,sicne both machine
 are same architecture and same OS)
 
 I can set break point to main.
 
 if I do step or next, I am getting the error message "cannot find 
bounds of current function"
 
 if I do continue, I am getting the error message " program received 
SIGSEGV, segmentation fault"
 
can anybody tell me where is the wrong ?
 
Is there anything's need to be take care while building the gdb in one 
machine. ?  currently I am using the default gdb installed in machine 
due to both machine are same architecture.

You should not do that, gdbserver already loaded the program.
The rest of your problems may be related to this step.

remote debugging

[Patricia Alba]

hi !
i'm using gdb to debug an application on a remote
target (hitachi 16-bit microcontroller). i downloaded
the gdb stub for a different version and ported it to
work on the board i'm using. i'm able to connect, but
the gdb is unstable. it generates a sigtrap exception
for even normal termination of the program. the values
of local variables are also not working correctly.
any pointers on how to go about debugging the
debugger??

Remote Debugging

[Tim]

I running gdb 5.2-2 and gdbserver.  Remotely I'm running kernel 2.4-19.
I compiled gdbserver against uClibc.  My app is statically compiled
against glibc 6.

My remote device is an x86 board.

My app is compiled with -ggdb and is not stripped on either the remote
or the host.

I start gdbserver 192.168.0.1:2345 myapp -options on the remote device. 
I start gdb on the host and give it the command target remote
192.168.0.2:2345

the remote device shows a connection from my host.

then I give it the command load myapp.

After all this I cannot view any source.  The 'l' command returns the
error 'no symbol table loaded' and instructs me to use file.

What am I doing wrong?

thanx!

Try skipping this step.  You should not use load with gdbserver.

Also be sure to give GDB the executable before connecting, i.e. "gdb
myapp".

remote debugging

[Vinayak P Risbud]

        Hi,
            I am trying to use remote debugging using LAN (Tcp/Ip) on
Redboot
            What I understood till now is,
                    1.  the main polls net_io_test function during idle
time
                    2.  The function net_io_test checks for
                                        tcp_sock.state == _ESTABLISHED
                    3.   If established, the control calls
net_io_assume_console
                         to setup debug channel.

                But,  after this, how the flow goes,  I am not able to
trace.
                my gdb client on remote PC sends $Hc-1#09 command,
                over tcp/ip link.
                I am not able to trace, where and how exactly this gdb
                command is read and processed (i.e trap is generated ?)

                Can any one help in tracing the flow ?

            Thanks in advance
                Vinayak

As Fernando mentioned, how to integrate/use the sample stubs is
described in the manual.  If after reading that section you still have
specific questions, don't hesitate to ask them.  We'll do our best to
answer them, as well as improve the manual to make it clearer.

Hi,

i have found a site http://www.ocdemon.com which offers the gnu
toolchain with support for wiggler/raven JTAG interfaces.  I have not
tested this and would like to know if anybody has some experience with
this. The sources for the Wiggler drivers are not included in the
distribution.
Is there any person related to this site? I cannot find any name on the
sites pages.
Is there something illegal behind this?

As far as I have figured it out, the standard gdb release supports the
ARM RDI interface. This requires the ANGEL software installed
(and is then connected via a serial interface).

Optionally the OLD EmbeddedICE Box which can interpret the RDI commands
to JTAG
commands can be used. The new MultiICE debug box from ARM requires
software support on the host which is not available for linux at the
moment.

There is a configure option --multi-ice in the gdb release which
lets me assume that the commercial GnuPRO tools from Redhat
have support for the MultiICE. The multi-ice-gdbserver seems not to
be under GNU license.

The JEENI JTAG interface from http://www.episupport.com seems understand
the RDI commands
directly as the ARM EmbeddedICE does. So this is also usabled via the
gdi rdi interface.

http://www.abatron.ch also offers a JTAG interface but with a dedicated
gdb driver
software for linux. gdb.

Is anybody using the wiggler with gdb for the ARM7?

Which software are you using?

Is anybody out there who is putting effort in writing a GNU-licensed
remote interface
for a low-cost JTAG interface like the wiggler?

Nope.  You cross compile your executable with "-g".  Create a stripped copy 
(not necessary if you don't care about file sizes in the target) and copy
the stripped version to the target.  Load it with gdbserver.

On the host side:  gdb <your-complete-executable-with-debug-info>
and proceed as you mentioned.

But please, before you try to go any further, print a copy of the 
"Debugging with GDB" manual.  It is in the doc directory (you can make it in
various flavors - ps among them).  It is also available as an info topic 
if GDB is correctly installed on your system.

Thanks for responding

You are correct. The breakpoint in  "...some more code ..." is never
reached. We are suspecting
at the moment that it is a problem with the ProcessSleep function since the
hang occurrs when we
'step into' or 'step over' it. What we don't know is whether it is a
problem with our underlying kernel
functions or whether GDB has a problem with a "sleep" function which
allocates a semaphore,
blocks on it subject to a user specified timeout and then returns the
semaphore. We are leaning
to suspecting that it is a problem with our custom kernel (i.e. GDB is
innocent). However I thought
I would ask the GDB group, with all the combined experience developing GDB,
just in case they
saw something obvious.

Thanks again

A alternative might be to modify gdbserver (or the like) and use GDB's
remote protocol (target extended-remote).  (I'm not sure what a CAN
network is).

Are you loading different files or the same file?

	(gdb) file  foo.out
	(gdb) target .....
	(gdb) load

both loads the file and updates the symbols.  There are also commands
for loading symbols from a specific file.

I've seen this done two ways:

	o	the embedded equivalent of crt0.o
		initialises the stack (and zero's
		bss)

	o	*_create_inferior() performs
		the initialize operation.
		(see remote-sim.c)

If someone else is willing to do the implementation for "info float",
I'm willing to integrate the patches.  (I rarely have need for "info
float", so it may be better if someone else did the implementation.)
OTOH, if no one sends me patches, I'll try to get to it eventually.

Does it work if you disable your shared library breakpoints first?

I've seen this problem before on other platforms.  It would really be
nice to have a relatively small test case to debug this problem with. 
Do you think you could whittle the problem down to something that you
could send us the source to?  

It'd also be nice to incorporate such a test into the test suite.  If
you can provide me with a C program which exhibits the problem, I'll
work on the expect script to incorporate it into the test suite.  (I'll
also work on tracking down the bug and fixing it.)  Remember that we'll
need copyright assignments for anything that winds up in the test suite.

You may (or may not) find it useful to start with the shared library
tests already in the test suite.  Take a look in gdb/testsuite/gdb.base
at the files shmain.c, shr1.c, and shr2.c.

BTW, I just fixed one of the bugs (there were actually two separate bugs)
which was causing one of the shared library tests to fail.  I'll commit
this fix later on today, but I doubt it will solve your problem.

Thanks,

Kevin

Ok, I just wanted to clear the status of "info float", I'll take a look at 
it too and maybe I should already think about "info vector" :-)).
