Hello, i am new for using STM32 cube ide.

İ am following some online courses and when i was in debug part, i got this error :

i looked some solutions on google but , i couldn't fix this. What should i do ??

Can STM32CubeProgrammer connect to the device? Did you reboot? Power cycle the debugger?

i did reboot, but i don't have any board , i mean any usb device for pc.

Should i buy board like stm32fdiscovery to test my codes ?

Well you need a debugger to program efficiently. Most ST boards have them built in. What board do you have? If none, then you need one.

Looks like your stlink driver or​ stlink gdb server are not working properly. Reinstall stlink drivers, update stlink firmware, restart your pc and try again
