            "content": "This manual page documents briefly the dfu-tool command.\n\ndfu-tool allows a user to write various kinds of firmware onto devices supporting the USB De‐\nvice Firmware Upgrade protocol.  This tool can be used to switch the device from  the  normal\nruntime  mode  to  `DFU  mode'  which allows the user to read and write firmware.  Either the\nwhole device can be written in one operation, or individual `targets' can be  specified  with\nthe alternative name or number.\n\nAll synchronous actions can be safely cancelled and on failure will return errors with both a\ntype and a full textual description.  libdfu supports DFU 1.0, DFU 1.1 and the ST DfuSe  ven‐\ndor  extension, and handles many device `quirks' necessary for the real-world implementations\nof DFU.\n",
