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"

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.
