STM32F0 quits it's service

Question asked by gnoss.juergen on Jan 7, 2013
Hello,

strange thing happened.
I setup a development environment
Linux - gcc - eclipse- openocd st-Link V2  STM32F0 and F4 Dicovery boards.
And I started to port a lot of my libs to STM32

Every thing runs fine until an hour ago.

I changed the eclipse workspace while openocd is still running and a telnet connection waiting for a command.
eclipse complained the running tool but closed it (no other option there) and started the other workspace. Generally I'm not doing this, but occasional it happens. It was not the first time.

In the new workspace I tried to openocd - connect to the board but the board doesnt answer.

here the error from openocd

The problem is definitive on the STM32F0discovery

I have another STM32F0Discovery working fine with same configuration.

Any ideas?

Thanks
