The firmware installation of the CR6SE printer has been failing. I have tried many methods, including using an SD card to copy the firmware and burning the firmware with a USB cable. The display is “[src/stm32/Makefile: 111: flash] Error 255”
From the log it seems that the first issue is that your user is lacking the required permissions.
Login as your Klipper username and call:
sudo usermod -a -G dialout $USER
sudo usermod -a -G tty $USER
Log out and back in, then try again.
Hello and thanks for the help. I’ve tried the command you sent and it still doesn’t solve the problem
I looked at the permissions, and below is the system information
lrwxrwxrwx 1 root root 13 Nov 2 02:13 /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 -> ../../ttyUSB0
crw-rw---- 1 root dialout 188, 0 Nov 2 02:13 /dev/ttyUSB0
Is there any other solution, please
Log in and show the results of the command:
groups lee
root@orangepi4-lts:~# groups lee
lee : root tty dialout video
Did you reboot after modifying the groups? If not then try it.
What OS are you using? The groups of your user seem quite strange for a regularly established user.
Also follow How-To Trouble-Shoot and post the dmesg.txt

The hardware I’m using is an orange pi
the OS is Ubuntu 22.04.3 LTS
Orange Pi 3.0.6 Jammy with Linux 5.18.5-rk3399
I have no idea what’s wrong. I would guess that something is messed up on the Linux side. The Orange Pi Linux distributions are terrible.
I’d recommend to start over and use Armbian as basis: Orange Pi 4 and LTS – Armbian
