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 🙂

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

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:

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
