DESCRIPTION

The program dfu−suffix can be used to add, check or remove a DFU firmware file suffix, recommended for safely matching a firmware file and device.

Note that a suffix is recommended by the DFU standard, but not required. A DFU host tool like dfu−util will recognize the suffix and use it to check that the device is matching, but not transfer the suffix to the device.

dfu−suffix −−check firmware.dfu

Checks the file firmware.dfu for a valid DFU suffix

dfu−suffix −−delete firmware.dfu

Removes a valid DFU suffix from the file firmware.dfu
