I would like to know if my nucleo board is dead or if I can recover it.

For some reason I cannot flash my Nucleo (STM32F446) board anymore. It used to work well... I got the following message:

openocd -f ./cfg/openocd.cfg -c "program ./build/ch.elf verify reset" -c "shutdown"

** OpenOCD init failed **

shutdown command invoked

Makefile:210: recipe for target 'flash' failed

make: *** [flash] Error 1

Also when I am issuing:

telnet localhost 4444

I get:

Trying 127.0.0.1...

telnet: Unable to connect to remote host: Connection refused

When I plug my Nucleo board I can see its build version etc. Strange.
