[Qt-creator] BM: Problem with breakpoints when debugging of ARM on Windows using openocd

[Denis Shienkov]

Hi All,

I've :

* Windows 8 x32
* QtCreator v3.3.0 (from snapshot)
* ARM GCC toolchain: gcc-arm-none-eabi-4_8-2014q3-20140805-win32.exe
* OpenOCD from:
http://gnutoolchains.com/arm-eabi/openocd/OpenOCD-0.8.0-Win32.zip
* GDB 7.8 with Pythos support, from this WIKI:
http://qt-project.org/wiki/QtCreatorBuildGdb
* Target - stm23f4discovery

The OpenOCD is running with this command:

"c:\openocd\bin>openocd.exe -s c:\openocd\share\openocd\scripts\ -f
board\stm32f4discovery.cfg"

And I get a following info output:
"

The BM plugin of QTC are configured as:

"
GDB host: localhost
GDB port: 3333
Init commands:
- monitor reset halt

- load

- monitor reset halt

Reset commands:

- monitor reset halt

"


= PROBLEM =

When try do setup breakpoint in QtCreator, I got following error:

"
Cannot continue debugged process:
Warning:
Cannot insert hardware breakpoints:
You may have requested too many hardware breakpoints/watchpoints
"

and from the OCD console I see:

"
Info : only breakpoints of two bytes length supported
Error: can't add breakpoint: resource not available
Info : dropped 'gdb' connection
"

>From this resource:
http://sourceforge.net/p/openocd/mailman/message/32178948/
I found out, that, seems need to re-build the OCD with a patch to cutting
of DBG command
length.

But, this is strange, because on Linux host, the debugging with OCD works
without any problems..


So, can anyone help me with this issue?

BR,
Denis
