Hi I´ve problem with programming stm32l053, after debug get error ''Cannot identify target as a STM32L family''. I´m using Eclipse Indigo under Linux, st-link/v2 debugger, OpenOCD, arm-none-eabi-gdb. My reports

Open On-Chip Debugger 0.8.0 (2014-11-06-14:05)

Licensed under GNU GPL v2

For bug reports, read

    http://openocd.sourceforge.net/doc/doxygen/bugs.html

Info : This adapter doesn't support configurable speed

Info : STLINK v2 JTAG v21 API v2 SWIM v4 VID 0x0483 PID 0x3748

Info : using stlink api v2

Info : Target voltage: 3.203137

Info : stm32lx.cpu: hardware has 4 breakpoints, 2 watchpoints

target state: halted

target halted due to debug-request, current mode: Thread

xPSR: 0xf1000000 pc: 0x080045b8 msp: 0x20002800

STM32L: Enabling HSI

Info : accepting 'gdb' connection from 3333

Warn : Cannot identify target as a STM32L family.

Error: auto_probe failed

Error: Connect failed. Consider setting up a gdb-attach event for the target to prepare target for GDB connect, or use 'gdb_memory_map disable'.

Error: attempted 'gdb' connection rejected

symbol-file WorkSpace/projectxx/Debug/projectxx.elf

monitor reset halt

''monitor'' command not supported by this target.

load WorkSpace/projectxx/Debug/projectxx.elf

You can't do that when your target is `None'

Perhaps something you'd actually want to pursue with the OpenOCD people? The STM32L0 part is relatively new, and perhaps not adequately supported in your chosen software.

Problem was solved by using OpenSTM32 - ''Workbench for STM32'' plugin for Eclipse. Now it´s OK
