I'm feeling stupid
, finily I have crate a simple cfg file that allow me to connect to the board with openocd by using the following command in a terminal:
openocd -f st_nucleo_l011k4.cfg
In another terminal, I can run gdb:
arm-none-eabi-gdb

Error finishing flash operation
I have add my openocd cfg file for nucleo L011k4
I still have an error when I try to flash the board with openocd.
The same result if I try to use telnet connection trough telnet localhost 4444
Any idea

Theo,
try this
Add it in openocd\scripts\board
It sets working area size to 2k (default script set it to 8k exceeding real flash size)

Yes it was my problem, a have modify my cfg to specify the working area:
source [find interface/stlink-v2-1.cfg]
transport select hla_swd
set WORKAREASIZE 0x0800
source [find target/stm32l0.cfg]
reset_config srst_only
It work now, I can program the board trough the openocd and gdb connections.
I'm going to test with your zip just to make a comparison.
Your method is may be better because you store your file in openocd folder rather than what I'm doing for now. I store the cfg file in my project

Thanks RoccoMarco,
Now I can program the board with openocd+gdb, I finally added your cfg file to the openocd path.
What about st-flash do you have a way to resolve the problem for this tool? It is a good alternative when I don't want to debug, I can quickly program the board by adding a rules to the make file.
So I will be happy if you also have a solution for st-flash.
Thanks you a lot for your help.
