MCU 'mcu' configured for 64Mhz but running at 63Mhz!

So let’s work through the errors one by one and start with this one. Could you explain the steps you went through exactly, not “I followed the instruction to flash the firmware.” The more complete information you provide, the faster things can get fixed and you can get back to printing.

Along with explaining the process you followed, could you post your new klippy.log and printer.cfg? Let’s see if I we can figure out why you can’t get a connection while we work on the makefile error.

ok, looks, like that i got it now.
The flash to klipper 12 worked, but killed the klipperscreen.
I reinstalled the provided image on the cb1 and was abled to make all the updates.
klippy (3).log (68.0 KB)

Not the way, it´s ment to install but seems to work now

Good stuff. The MCU config statement looks better (and more complete):

MCU 'mcu' config: ADC_MAX=4095 BUS_PINS_i2c1_PA9_PA10=PA9,PA10 BUS_PINS_i2c1_PB6_PB7=PB6,PB7 BUS_PINS_i2c1_PB8_PB9=PB8,PB9 BUS_PINS_i2c2_PB10_PB11=PB10,PB11 BUS_PINS_i2c2_PB13_PB14=PB13,PB14 BUS_PINS_i2c3_PB3_PB4=PB3,PB4 BUS_PINS_i2c3_PC0_PC1=PC0,PC1 BUS_PINS_spi1=PA6,PA7,PA5 BUS_PINS_spi1a=PB4,PB5,PB3 BUS_PINS_spi2=PB14,PB15,PB13 BUS_PINS_spi2_PB2_PB11_PB10=PB2,PB11,PB10 BUS_PINS_spi2a=PC2,PC3,PB10 BUS_PINS_spi3=PB4,PB5,PB3 CLOCK_FREQ=64000000 MCU=stm32g0b1xx PWM_MAX=255 RESERVE_PINS_USB=PA11,PA12 RESERVE_PINS_crystal=PF0,PF1 STATS_SUMSQ_BASE=256 STEPPER_BOTH_EDGE=1

Let’s see what happens when you try a print.

I just got this error, for the first time ever, after accidentally overloading my PSU ( set bed and nozzle temps at the same time), and upon reboot i hav the error.
Not concerned, it’s just odd that it appears now… after an inane reset that I have probably done half a dozen times by now.
