Describe your issue:

Hello,

I’m trying to update Klipper on my printer, but I’m currently stuck. I managed to update the firmware on the mcu, bit I can’t get the host to update. I followed the guides below and I’m out of ideas.

If somebody has an idea, I would be grateful.

cd ~/klipper
git pull
~/klipper/scripts/install-octopi.sh

https://www.klipper3d.org/SDCard_Updates.html

sudo service klipper stop
cd ~/klipper
git pull
make clean
make menuconfig
make
./scripts/flash-sdcard.sh /dev/ttyACM0 btt-skr-v1.3
sudo service klipper start

Here is the error message that I’m getting.

Recv: // mcu 'mcu': Command format mismatch: config is_config=%c crc=%u move_count=%hu is_shutdown=%c vs config is_config=%c crc=%u is_shutdown=%c move_count=%hu

See MCU Protocol error caused by running an older version of the firmware

You probably did not update your MCUs correctly. If in doubt, use the same approach as for the initial flashing.

Thx for the help, but I didn’t manage to get it to work. I reinstalled everything and it works now.
