skr v1.4 turbo unable to connect raspberry pi 4b with serial connection gpio


Recommended Posts

Hello

I am new to BigTreeTech. I just bought a SKR v1.4 turbo to use on my Ender 3 Pro. I am trying to connect to my raspberry pie using the GPIO pins. I have it setup correctly. Everytime i try to connect it tells me it is unable to establish a connection with the SKR v1.4 turbo. Please help

 

Steps for connection:

dtoverlay=pi3-disable-bt
enable_uart=1

deleted the following from /boot/cmdline.txt:

console=serial0,115200

diabled getty:

sudo systemctl stop serial-getty@ttyS0.service sudo systemctl disable serial-getty@ttyS0.service

set firmware serial ports to (and have tried the inverse of the below:

#define SERIAL_PORT 0 #define SERIAL_PORT_2 -1

I've also tried several other ports /ttyAMA, etc. and none work. very lost here.
