Switching to DFU mode is no longer possible #16

For reasons unknown to me I can no longer switch to DFU mode. The Levithan is installed in a working printer and no other USB devices are connected

Here is the dmesg output after pressing the boot and reset buttons as described in the instructions:

Do you have an STLink V2? You could use this to check whether the MCU is still accessible via the SWD interface.

MarkusNiewoehner commented 5 months ago

Yes, but I've never used it before. I'll see if I can try that one day. I was now able to flash the Levi with the current klipper via catapult.

Does the 3.3V LED light up when the board is powered?

MarkusNiewoehner commented 5 months ago

In 24V operation or 5V USB? I can check tomorrow.

JNP-1 commented 5 months ago

In 24V operation.

MarkusNiewoehner commented 5 months ago

I'll report back tomorrow morning.
