Update Klipper Kingroon KLP1 230

Good morning

I tried to update Klipper on my Kingroon kLP1 230 printer and I now get this error:

`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: v0.12.0-286-g81de9a86
MCU(s) which should be updated:
mcu: Current version v0.11.0-122-ge6ef48cd-dirty-20230817_150801-mkspi
MKS_THR: Current version v0.11.0-122-ge6ef48cd-dirty-20231010_174111-mkspi
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 ‘MKS_THR’: Command format mismatch: query_adxl345 oid=%c rest_ticks=%u vs query_adxl345 oid=%c clock=%u rest_ticks=%u
`
I tried the following method by ssh accessing the printer:

sudo service klipper stop cd ~/klipper git pull make clean make menuconfig make ./scripts/flash-sdcard.sh /dev/ttyACM0 btt-octopus-f446-v1 [[[manually power-cycle the printer board here when instructed]]] ./scripts/flash-sdcard.sh -c /dev/ttyACM0 btt-octopus-f446-v1 sudo service klipper start

but here is the feedback I got:
root@mkspi:~# cd ~/klipper -bash: cd: /root/klipper: No such file or directory

Have you seen a solution to offer me?

THANKS

Yeah man same issue here, I tried installing the latest armbian software for the mkspi part of the board and reflashing the mcu from sd as well

I don’t have an actual RPI and in the past I think I have encountered something similar with compiling and flashing from something other than actual RPI like a BTT Pi and I bought an actual pi just to compile my kipper.bin file and it ended up working, I might buy another pi to see if this would work
