Hello good evening, can someone help me? The sm32 on my gemini v3 has disappeared... I tried all day to flash the klipper to the mcu, now it's completely gone and doesn't recognize it anymore... I've already reinstalled the firmware on the sd but still nothing appears.

have you been setting the boot0 and boot1 jumpers as per https://mellow-3d.github.io/fly-gemini_v3_klipper_mcu_usb.html

it would be better to continue here
you will need to SSH into your gemini and see what lsusb is reporting
which operating system image did you flash to the SD card?
hollow tree
and have you managed to gain SSH access?
hollow tree
are you aware of this, regarding the USB ports, also?
hollow tree
i'm referring to the fact you cannot use the USB crossed out in red as that port is used internally to connect to the stm32
i can't tell if that's the case from your photos

It's a bit complicated to remove the cables but not the USB output marked in red, I left it unused
hollow tree
and what else is plugged in
compact delta
The hotend
hollow tree
what is plugged in to USB.

so if the jumpers are still placed as in your last photo of the board, what do you see in lsusb if you hit the reset1 button
compact delta
I did this now putty doesn't open even via usb
I think I'll have to reinstall the firmware on the SD, wouldn't that be better?

you need ssh access to be able to continue. it looked like it was booting successfully before.
