Describe your issue:

mcu ‘mcu’: Unable to connect

Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer

I’ve re-installed klipper quite a few times , and have also checked mcu serial , multiple times , and for info
klipper is active
”mcu is not connected “ this is the only issue that I’m having right now , also want to know does this board support klipper at first place , because i know these 2560 boards are supported , and their cfg files are available for reference

Since , I’m unable to find a proper solution for this issue , I’m trying to find an answer here , and I’m in a very urgent need to complete this klipper work and move ahead , so any response regarding the same is much appreciated

Hello @Sarvesh0205 !

How did you flash that board?

@Sarvesh0205

MKS GEN V1.4

[Sarvesh0205]

via make menuconfig

then

MCU Architecture: Atmega AVR

Processor Model: ATmega2560

Communication: UART 1
BAUD RATE : 250000

Flashed using this : make flash FLASH_DEVICE=/dev/serial/by-id/ usbFTDI_FT232R_USB_UART_AD0JMQNT-if00-port0

this is the serial aswell : /dev/serial/by-id/ usbFTDI_FT232R_USB_UART_AD0JMQNT-if00-port0

if you want I can drop in printer.cfg aswell ,
hopefully we can fix this issue

thanks for the quick reply mate
