STM32 Nucleo H755ZIQ - Error in initializing ST-LINK device. Reason: No device found on target.
I am part of a small team trying to build a small robot as our Hobby. Most of us are without a lot of knowledge on Electronics, so we turn to ChatGPT for most of our development.
We started our work on this particular Evolution board. We have used it to test our sensor integration, UART communication, and it has worked fine so far.
Yesterday, we tried running our BLDC motor using a motor driver. I am not sure if the connections and code were accurate since we followed ChatGPT's instructions. But after our first test, we haven't been able to flash the board again and keep getting this error.
I followed the solution pasted here earlier, but even after connecting BT0 to 3.3v, it doesn't connect in the STM32Programmer, and we are unable to erase the chip.
Also, whenever it's connected, the ST Link section and the CN7 part of the board heat up pretty quickly.
Any guidance on how we can proceed forward will be much appreciated. We are a group of recent graduates, and we can't
afford to keep busting boards like this.
