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: " Open On-Chip Debugger 0.8.0 (2014-05-02-12:11) Licensed under GNU GPL v2 For bug reports, read http://openocd.sourceforge.net/doc/doxygen/bugs.html srst_only separate srst_nogate srst_open_drain connect_deassert_srst Info : This adapter doesn't support configurable speed Info : STLINK v2 JTAG v21 API v2 SWIM v0 VID 0x0483 PID 0x3748 Info : using stlink api v2 Info : Target voltage: 2.914184 Info : stm32f4x.cpu: hardware has 6 breakpoints, 4 watchpoints Info : accepting 'gdb' connection from 3333 Info : device id = 0x10016413 Info : flash size = 1024kbytes ... ... " 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
