i’m trying to use Arduino nano + MPU 6050 to calibrate inpute shape, but i’m getting this error when i put the mpu6050 config below
[mcu nano]
serial: /dev/serial/by-path/pci-0000:00:1a.0-usb-0:1.5:1.0-port0
[mpu9250]
i2c_mcu: nano
i got this error then restat firmware
MCU Protocol error
This is frequently caused by running an older version of the
firmware on the MCU(s). Fix by recompiling and flashing the
firmware.
Your Klipper version is: v0.11.0-311-g9e765dae-dirty
MCU(s) which should be updated:
mcu: Current version v0.11.0-311-g9e765dae-dirty-20231106_172016-klipper-To-be-filled-by-O-E-M
nano: Current version v0.11.0-311-g9e765dae-dirty-20231107_004816-klipper-To-be-filled-by-O-E-M
Up-to-date MCU(s):
Once the underlying issue is corrected, use the “RESTART”
command to reload the config and restart the host software.
mcu ‘nano’: Unknown command: i2c_write
