Pi 4B with Cheetah 3.0 problem

[SzaryPB]

Boards are connected via dupont and USB-c - microUSB-C, after typing lsusb in MobaXterm where is no motherboard showing.
5V, 12V 24V leds are ok.
USB cable is OK, I wrote firmware again via STM32CubeProgrammer but it doesn't help.
What I'm doing wrong?

[SzaryPB]

Problem solved.
I've reinstall mainsailos, make new firmware and now I see motherboard

@SzaryPB having same issue. What option do tou set for USB and BOOTloader in menuconfig for Cheetah V3 ?

[SzaryPB]

@Minims Hi! I create firmware without Bootloader and use STMCubeProgrammer to insert firmware into motherboard.
the same settings as here: https://github.com/FYSETC/FYSETC-Voron-0.2-Pro/blob/main/Firmware&OS/makemenuconfig.jpg?raw=true

Oh thanks @SzaryPB, I miss this thing.
So now I can see my serial-id, I have updated in klipper config, but klipper still saying it can't connect to MCU, digging...

I have the same problem, I have the correct id in printer.cfg but klippy.log still tells me "mcu 'mcu': Unable to open serial port: [Errno 2] could not open port "[...]
Did you find any solution?

I finally make it work with
make flash FLASH_DEVICE=xxxx:xxxx
Which the lsusb device id ,
You may have it in the bash history.

on my side i will make a new sdcard with klipper once.i have finish my build

I made it work now by using ls /dev/serial/by-path/ instead of /by-id/ and using that in the printer.cfg which for some reason works but the other way does not. Then I forgot to flash the voron display and setting the path in the config as well, just for anyone else who may have the same problem. (Also mind the connection picture for the display, black to the 5v marking on the pcb and red to the gnd marking, weird but that was also an issue)

seems there is some issue with 64 bit os for pi. I can't see /dev/serial/by-id/ but there is a device inside /dev/serial/by-path/ after I reinstalled os to raspberry pi lite 32 bit I can see the board under /dev/serial/by-id
