Hey, just got my new 4.2.7 board for my Ender 3, finished installing klipper & mainsail on it, but it seems that klipper can't communicate with the mcu as the photo shows, in my printer.cfg, the serial path for the mcu is /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 as the example shows, and it does show on my raspberry pi when I list it
The mcu is also flashed
I'm not entirely sure is the mcu is flashed, but the printer motors are working, since I can't move any axis, and the screen does power on
lsusb also shows it
signal pebble
then its not flashed successfully
pls use the search. there was already some posts about flashing this board

cool thanks!

It seems that I don't have the same problem as others
My printer does appears in /dev/serial/by-id/...

This is normal with the ender boards, because they use a ch340 UBS to serial chip. If you don't see it, your creality board is dead

oh sorry, forgot to answer you..
actually, my micro-usb to micro-usb cable was half-dead, so it wasn't working when I was touching the cable a little bit
but now it works well :)
