failed to init Unable to read tmc uart
Hi all... i'm sure there is a simple solution that is staring me in the face, but i'm blind right now. My original board was Octopus 446, because of an issue, i ordered and got an Octopus V1.1 board to put in it's place. I'm past my original issue that I had on my 446 board, but now it's having trouble with the motors. I've followed this: https://v-core.ratrig.com/electronics/#bigtreetech-octopus-v11-wiring-diagram z probe and all end stops work just fine. I get the following error on all the stepper motors: stepper_x failed to init: Unable to read tmc uart 'stepper_x' register IFCNT
First off, yes, i removed all the jumpers except the 1 on all the drivers. That was the very first thing I did before I started hooking it up. Since it's with all of the drivers, there is something else i've missed and not sure what it is.

i guess if you changed the board you need to change it also in the printer.cfg board declaration type, as the pinout might be different
unless you've already done that
yea, already did that.
does the MOTOR side have power ? is a stepper not shorted ? the drivers are powered by the motor power connector
what is the best way to confirm that? I'm not an electrical expert by any means.
I just found a wiring difference between the Pro 446 and V1.1 going to shutdown and fix that
