Describe your issue:

I’m sorry there was a lot going on in the klippy log. I was chasing down a BTT .cfg error and now I am chasing my tail. Not sure where to begin. Most recent entries into the log I believe are saying there is an MCU connection issue. I have done the ls /dev/serial/by-id/ and have gotten a reply with “usb-STMicroelectronics_MARLIN_STM32G0B1RE_CDC_in_FS_Mode_205132455942-if00”. This is what I entered into the printer.cfg under [mcu] with serial: prefacing it. No clue whats going on now.

SELF RESOLVED. Leaving answer here for others in case they have the same issues. Notice that my previous USB output included MARLIN in the name? I am converting from marlin to klipper, and my SD/TF card was NOT flashing. I switched to my 3rd card and the flash finally took, if all else fails… try a different TF card.
