I am getting these error messages while I upload my code to the board. How to solve it? can anyone explain?

What board do you have and how is your programmer attached to the board? Show pictures.

What host and OS ?

If you use Linux, your user needs to be added to the appropriate groups to access USB devices.

I would suggest the following steps to help investigate and solve your issue:

1. Please verify the connection using STM32CubeProgrammer to ensure there are no issues with the board.
   • If you don't have STM32CubeProgrammer, you can check using the ST-Link GDB server in STM32CubeIDE to confirm whether the issue is related to OpenOCD.
2. If STM32CubeProgrammer is ok, then for sure we have an issue with OpenOCD. To help us investigate your issue, could you please share with us the OpenOCD log with higher verbosity (use -d3)?
