I’ve been trying to solve this issue I’m having with flashing my STM32 nucleo F303re dev board. I was able to flash the board just fine. A day later I started getting the below error. I’ve tried a different USB cable, Ive made sure that it’s using st link v2.1. I’m pretty new to MCU. Here is the error:

Here is what what running dmesg (I’m using a linux OS) gives after disconnection the USB and reconnection the USB to the dev board:

I’m new to openOCD and ST link so any guidance on what is going on there would be much appreciated!
