Gdb work with openocd in pipe mode,but in C::B ,some message seems missing ?

[jjingwer]

Gdb can works well with openocd when  it run in  cmd or powershell   in pipe mode , but  in C::B ,  it seems  some message always missing. Gdb can not  get enough message.

It  look is  like this :

Is the full debug log enabled?
Settings->Debugger->full debug log

Can you post a cmd version and a codeblocks version in code tags (the # symbol in the forum text editor)?

[jjingwer]

@BlueHazzard
yes , full debug log

[BlueHazzard]

Please use the # symbol to post logs.
This should look like this

Code

This is a log 

I see only this difference:

Code

[debug]Remote replied unexpectedly to 'vMustReplyEmpty': PacketSize=4000;qXfer:memory-map:read+;qXfer:features:read+;qXfer:threads:read+;QStartNoAckMode+;vContSupported+

This comes from GDB, so is the connection to your target not stable?

A quick google search showed that it is possible a bug in gdb. Are you sure you are using the same version of GDB from command line and from codeblocks?

[jjingwer]

@BlueHazzard


I am  using the same version of GDB ,  and  the only difference is  :

Code

[debug]Remote replied unexpectedly to 'vMustReplyEmpty': PacketSize=4000;qXfer:memory-map:read+;qXfer:features:read+;qXfer:threads:read+;QStartNoAckMode+;vContSupported+

And  It did happens  in cmd, But when I   add

Code

fflush(stdout);

into  oenocd  and build it,   It  does not happend  again  in cmd. 
But in C::B  it still  happens  .

[BlueHazzard]

very strange...

If all executable are the same for cmd and codeblocks it should work...
Are you starting OpenOCD separately or trough codeblocks?

[jjingwer]

@BlueHazzard

I use C::B   to  start  Gdb .  And start Openocd  through  Gdb.

I get the infomation form Openocd  user guide

Code

21.1 Connecting to GDB
Use GDB 6.7 or newer with OpenOCD if you run into trouble. For instance GDB 6.3 has a known bug that produces bogus memory access errors, which has since been fixed; see http://osdir.com/ml/gdb.bugs.discuss/2004-12/msg00018.html

OpenOCD can communicate with GDB in two ways:

A socket (TCP/IP) connection is typically started as follows:
target extended-remote localhost:3333
This would cause GDB to connect to the gdbserver on the local pc using port 3333.

The extended remote protocol is a super-set of the remote protocol and should be the preferred choice. More details are available in GDB documentation https://sourceware.org/gdb/onlinedocs/gdb/Connecting.html

To speed-up typing, any GDB command can be abbreviated, including the extended remote command above that becomes:

tar ext :3333
Note: If any backward compatibility issue requires using the old remote protocol in place of the extended remote one, the former protocol is still available through the command:

target remote localhost:3333

A pipe connection is typically started as follows:

target extended-remote | openocd -c "gdb_port pipe; log_output openocd.log"

This would cause GDB to run OpenOCD and communicate using pipes (stdin/stdout). Using this method has the advantage of GDB starting/stopping OpenOCD for the debug session. log_output sends the log output to a file to ensure that the pipe is not saturated when using higher debug level outputs.

To list the available OpenOCD commands type monitor help on the GDB command line.

One way to connect Openocd is

Code

target remote localhost:3333

The other is

Code

target extended-remote | openocd -c "gdb_port pipe; log_output openocd.log"

I  used the second .

when in cmd or powershell ,  also  use cmd to start  Gdb and use gdb to start Openocd.


In fact , I  want to use the first way  , but  I can not   find plugins for  Openocd.

[BlueHazzard]

Code

target extended-remote | openocd -c "gdb_port pipe; log_output openocd.log"

So this line starts openocd from within gdb?
My guess is, that it starts the old version of openocd you still have in your path... Where do you have openocd installed? Where is your self build version of OpenOCD? Have you tried to use a full path to openocd in this command line?
Have you tried to start openocd from command line, and connect with codeblocks to it?
You can use processExplorer https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer to see the path from your executable if you hover the mouse over it. So start codebocks and your gdb setup, and look at the path of the started openocd

[jjingwer]

@BlueHazzard

I  can  set path  for C::B and cmd  ,so   I am sure  it is  the same Gdb and Openocd .

Also  I  can  set path in Gdb to start Openocd.

An almost debugger newbie, but, are you sure you are running the same "123456.elf" because it looks like you have different working folders being shown.

By the way , I  am a newcomer here ,but  I spent  years on debugger.

[BlueHazzard]

The thing is, in the logs you see everything that codeblocks sends to gdb, and everything gdb sends to codeblocks. I do not see many (or lets say crucial) differences.


Can you try to use the command line and execute exactly the same things codeblocks is executing?
You see what codeblocks is sending to GDB with the

I think  I may not  make  it  easy to be  understood.

In the C::B,  openocd   post  message to  Gdb ,but Gdb can not  get enough  message.

C::B  can  tell  you  what   C::B send to  Gdb and  Gdb  send to  C::B  , but  It can not tell  you  what  Openocd  send to  Gdb.

But they all  in C::B ,   Maybe   command  line  in   C::B  do not  have  eouch  buffer or  cache  ?

And  I  did a  test , I make  Openocd  to send more logs in  C::B:
