hi,

i tried “killall openocd” command in the terminal, the terminal says openocd : no process found . yes i am having the same issue when running a debug session , this time console says :

one thing i want to mention is that although my board is powered yet i cant see it in the device manager of linu (ubuntu version : 18.04.2)
. a notification always popup on the screen when we connect something on the usb port but when i connect my board on the usb no notification is showed . i m not the expert but i think it is something related to drivers . i tried connecting it on a windows10 operating system same problem persist. the device manager is not even showing unknown device found under usb peripherals section eventhough i have installed all the drivers properly .
