I purchased this board as an upgrade for my Ender 3v2 in April 2023.
It ran well for a few years, but recently the board lost its bootloader.
Because the board refuses to read an sd card I need to flash the uC with a debug tool. (SWD?) I purchased a good knock off on Amazon.
The ST-Link Utility I downloaded from https://www.st.com/en/development-tools/stsw-link004.html#overview
I grabbed a random bin file from the internet... here
ST-Link didnt work. I needed ST32Cube instead...
