Failed to start GDB server Error in initializing ST-LINK device. Reason: (4) No device found on target.

[User1654289054429807592]

Hello,

I am using an STM32G031 Nucleo 32 board. Everything worked well. Following break point I lost the gdb server connection. Unable to reconnect, I made an update of the driver st link. 

I started under reset, reinstalled an old st link driver... 

I have a second board, everything worked well for several days and impossible to connect to the server GDB. I don't know what to do anymore 

I read a lot of post on this forum and test diffrents possibilities. I need some helps.

 

Thanks in advance

Try Connect Under Reset options

Try with BOOT0 pin pulled HIGH

Use STM32 Cube Programmer, get part erased

Use connections speeds between 1-4 MHz
