serialhdl.error: mcu ‘mcu’: Serial connection closed
Issue:
mcu ‘mcu’: Unable to connect in mainsail.local
I have tried to flash the mcu mutilbe times.
in make menuconfig:
[*] Enable Extra low-level configuration option

(115200) Baud rate for serial port
I have tried to flash via Serial and SD card.
the printer screen is blue. and I have no idea if the klipper firmware has been flashed successfully.
