Hi,
I wrote a code with stm32f407vg board on stm32cubeide.
There was no error in build, but when I run this program, there is error like title.
The full contents in error message is:
Error in final launch sequence:
Failed to start GDB server
Failed to start GDB server
Error in initializing ST-LINK device.
Reason: (255) Unknown. Please check power and cabling to target.
It's connecting on my computer properly, and when I run other program a few days ago, It was work well.
How can I solve this problem?
Thanks for any answer.

First check STLink with other sw utility or newer programmer. Use connect under reset.
