Buddy Board not flashing on prusa mini...

Hi all, I had a mini on a shelve, so tried to flash it, but... I just can't get anywhere. I've broken the tab, shorted the pins, screen in flash mode.... 12 mhz.... I've got everything ready but still get this : dfu-util: Warning: Invalid DFU suffix signature Any hope would be apreciated 🙂 dfu-util: A valid DFU suffix will be required in a future dfu-util release Opening DFU capable USB device... Device ID 0483:df11 Device DFU version 011a Claiming USB DFU Interface... Setting Alternate Interface #0 ... Determining device status...

Hi, dis you left the 512kb for the prusa bootloader? Or by the other hand did you try to overwrite the bootloader? Anyway try with another usb cable, i had issues with some usb cables The “normal” behavior is that after the first flash you will see an error message, but this is because the board can’t be restarted automatically But the progressbar will show 100% and the message is clear

Hi, sorry for the delay, my wife made me promise not to work for 48h.... I've used this menuconfig setup, with 12mhz. I believe I've not touched the bootloader by saving an offset ? But I'm just a printer 😉

I've tried 3 USB cables (I've had that pain before as well 😉 Even tried 3 USB sticks and SD that have successfully flashed other boards before. whilst you here.... I've been trying to install RatOS 2 this am on 2 Bear Einsy clones, that were previously on Mainsail. I couldn't get the install macro to work. I copied/pasted a (supposed) valid printer.cfg content, but then the console said It couldn't read Gcode ?!? I took both printers back home to put some time on them. I could do with some help, I'll then upgrade my own bears 🙂 (Even though you shouldn't fix something that is not broken....)

that's a known issue, update RatOS first (before installing the template). Will be fixed in next release.

Ohhh... thanks ! I'll check that Sorry, just to be clear: ratos.local/configure, select Buddy, generate firmware, then ? Jumper on pins ? USB stick ? Flash vi SuperSlicer ? Is the old way (Putty...) necessary? the 100% is shown on the mini screen or in SS / Flashing menu ?

then jumper on the pins and restart the board (switch off and switch on) sorry for the delay, but I had a baby and also moved to a new home, and I have many things to take care now

Thanks for the follow up. No worries, I have enough printers to play with 😉 Back on it... with some rage to get it running. Flashing keeps failing. Flashing firmware.bin on usb stick doesn't work, via ssh I get : Failed to flash to 0483:df11: Error running dfu-util If the device is already in bootloader mode it can be flashed with the following command: make flash FLASH_DEVICE=0483:df11 OR make flash FLASH_DEVICE=1209:beba If attempting to flash via 3.3V serial, then use: make serialflash FLASH_DEVICE=0483:df11 make: *** [src/stm32/Makefile:111: flash] Error 255 USB drive flash fails : when booting in DFU mode, the usb drive's led doesn't turn on. When booting the mini on normal mode, the led turns on.

I was at the same stage, but despite the error it worked and I could proceed in the wizard

Humm.... weird. After failed flashing, the Mini reboots with original prusa firmware
