Im trying to flash the board to klipper. i have a st-link v2 and have made it as far as it showing the sv-link on the linux pc but doesn’t show its talking to the mcu yet. From what i can find it because im not connected to the correct spots on the board. Any photo’s of the correct spot would be helpful.
Where did this number come from? It may be a serial number. Is the origonal board for your ender? If so I’d expect to see a V2.4.S1.
Thats the model # off the board. Its a STM32F401 chipset. I did a chat with Creality and they verified that i have the correct pins for the st-link, but the linux pc is not detecting the chip. they said to use the RST and GRD pins to start with but couldnt tell me where the RST point on my board is at. they said that someone would reach out in an email but i haven’t heard anything yet.
Can you show how you’re wiring the ST Link to your board?
Also try unplugging/replugging the ST link into your PC. Some of the clones only initialize correctly half the time.
