Hi @HangZhang
The board is powered by debug port and tried to debug, still i am getting the same error same as earlier.
Hi @Prudhvi_Raj
On another board, i reproduced this issue.
When i changed to jlink.
It can work.
Hope this will help you.

Hi @Prudhvi_Raj
I tested my board,
It can work.
I watched your error message,
It reported that the wire not connected,
So can you change another wire?

Hi @Prudhvi_Raj
According to the picture, this error is due to not connecting to the core.
So please check if this board is powered on and if it is connected to the debug port.
Hope this will help you.
