So, I have been messing with my printer trying to install klipper and have run into a few issues. When I go into mainsail I encounter “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 am not sure if this is because the klipper firmware was not flashed correctly on to my printer or some other issue. I have tried the provided configuration for the SD card as well as many other combinations and the only thing that changed was the screen getting stuck at the creality logo and the cr touch turning red. I am not sure if this means the firmware was flashed or just an error.
Just as another tidbit of information, when I do the command “ls /dev/serial/by-id/” I am returned “usb-1a86_USB_Serial-if00-port0”. I am also doing this all on an orange pi 5 plus.
Hopefully someone has some new insight into this issue as I have searched every depth of the web looking for a solution. Thanks!

I had it like that before and was still getting the error. I assume klipper is not flashed properly on the printer. I am able to easily flash to marlin but when I attempt to flash to klipper it either doesn’t work or I just get a blank creality screen as if it is frozen.

You had not and you still have not. Look at your log and if you ask yourself which file you have been editing, I do not know but the file you should be editing is:
No I did not do that but I just tried it and it doesn’t seem like it changed anything within the klippy.log file. I should be typing this under console right? klippy (14).log (435.1 KB)
I’ll attempt to flash it again, but I have tried those instructions, and it doesn’t seem to be flashing on to the printer. Do you happen to know what the screen should look like if the flash was successful? Should I flash marlin back on it before attempting the flash because right now it seems to be stuck on the creality logo.
Did you happen to succeed flashing your printer? I’ve run into the same issue, it seems: LCD screen gets stuck on the Creality logo (not blank screen, as expected) and the only way to get it back is to re-flash Marlin.
Looks like at least a few other threads with the same issue, one as recently as yesterday, so I’m finding it hard to believe it’s a problem where all of us aren’t following the (very simple) instructions in the repo.
