Hi!
Can you post a dump of the dfu-programmer commands and their output, if any?

Thanks

Hi Gabriel,

Of the methods mentioned on the wiki I find the dfu-programmer software to be the simples.
Before even trying to run dfu-programmer. Make sure you reset the Mizar32 board correctly (press and hold SW2, then press and let go of SW1, then finally let go of SW2). Your system should now recognises the dfu-bootloader on the Mizar. Your computer should detect a new USB-device:
03eb:2ff8 Atmel Corp.

Now you can try to talk to the dfu-bootloader, as per the wiki.
If you do not see the 03eb:2ff8 Atmel Corp. USB device, you can not use dfu-programmer to flash your Mizar32.

Regards,
Marcus

Hi Gabriel,

No you dont have to press SW2 while running dfu-programmer. As soon as
you release SW1 you can release SW2.
